      No, they are not 21 gallon tanks, no matter what any book says. They are 22 gallon tanks.

      FYI, When my message center says I've used 24.0+ Gallons since last refuel I am able to put it just about 25.5 gallons of gas into my 2000 Limited. This will bring the fuel right to the edge of the spout.

      I hope nobody is still using the message centers for fuel mileage results. Those are not accurate, every one I've seen or heard about over estimates mileage by about 10%. You have to check fuel mileage by actually writing down the amount of fuel pumped in, and doing the math, for multiple tanks of gas in a row. Checking one is also not accurate, due to obvious differences in conditions when filling, air conditions, parking being level etc. If you check it every time you fill up, then all variances balance out, and you can see accurate mileage figures.

      I have on rare occasions pumped more than 22 gallons into my vehicles, each time the gauge being right at empty, not on purpose of course. The most I've seen was 23.4 gallons, and I reported that gas station here, whether it helped to do it or not. I'd never been to that one before, it was near the interstate where I got off, seeing the gauge at empty.

      I pump in between 24 and 25 gallons at every filling when I am at just about absolute empty. This fills to the spout end.

      I would suspect that gas station if you ever do get over 22 gallons in, that should be very rare. I don't want to get the tank that empty, the pump is kept from over heating by the fuel.

      What is the minimum amount of fuel you think the pump requires for cooling? How much fuel do you think the filler tube holds?

      I think a few gallons left should be enough to keep the pump at the same temperature as the gas. I've been lucky too I think, to let the tank get too low sometimes. I'm going to be using higher flowing pumps very soon also. The stock 80 lt/hr level pumps don't have much stress really, but bigger pumps need extra consideration. I'm working on my 99 V6 truck now, and the tank has to be cleaned out from lack of use, so I'm going to put a new pump in it. Not to want to spend extra money I've bought the pump I plan to use for the 306 I'll swap into it later. It's a 255 lt/hr choice I want to use in two of my trucks, maybe three eventually.

      The filler neck won't account for much extra fuel, it's not easy to be able to fill the entire volume of the tank, so anything over 22 gallons points to an inaccurate pump at a gas station.

      I run my tank to where on the Message Center it says I have used between 23 and 25 gallons of gas. Every station that I fill up at (across the state and adjoining states) I put in between 24 and 25.5 gallons of gas (which fills to the top of the filler tube)

      I do "slow fill" after the pump clicks to top off.

      There could be a couple of gallons of air space left after normal filling, but the time to get more gas to fill that is more than most people will do. LOL, you are too patient Jim.

      The most I have pumped into my tank at one time with it filled to the very top of the spout is just a bit over 25 gallons.

      I had a close to empty experience two weeks ago. I drove to work and had no issues, but I knew I was close to empty as I got to work. I regularly buy gas leaving work, at the gas station next to my work.

      Unfortunately where I park at work is not a dead flat parking lot. The row along the fence where my designated spot is, slopes downward a very slight amount. That was just enough to uncover the pump inlet/sock. My engine started but only ran for a few seconds, I didn't think of the possible problem, until it sputtered, and quit.

      I borrowed the mower gas can and poured a couple of gallons in. I then drove easily to the gas station and filled up, with just over 20 gallons, maybe 20.3, I forgot the exact decimal amount. I'm sure I put in about 2 gallons to get it to start, I put three back in the mower gas can, for the maintenance guy who lent it to me. My tank functions as a 22 gallon tank, as all of my Fords have done.

      The tank in the 4dr is about four feet long, the pump sucks gas from about a foot from the back end. If the vehicle is parked downward(front down), it will run out of gas with plenty of gas left, say 1-4 gallons depending on angle.

      I can post an exact measurement if needed(I have my 93 spare tank outside). If you were to plug the end holes and fill it out of the vehicle, it's likely close to 25 gallons of volume. But I doubt you can force much over 22 gallons in one from empty, in the vehicle. Jim has some interesting experience with his one Explorer.

      I talk straight, that's just me, and yes it rubs some people the wrong way. I've never been politically correct or properly tactful, just honest to a fault.

      Here's an example; the 351's, all of them are actually 352's. The displacement is identical to a 352 FE big block, and Ford decided to misname all of the 351's because of the old 352's. Why in 1969 did anyone think an old defunct/rare big block name would ever confuse people. I call them 351's because I grew up with them, but I knew the actual displacement too.

      The stroker 302's with a 3.25" crank, those are all 332's, not 331's. I plan to build one soon, and I'll call it a 332. I plan a 351 for my Ranchero, but it'll be a 302 block with a 3.4" crank, and a .060" over bore, thus the same displacement as all 351's, but with 3V heads, so a 351-3V on the air cleaner decal.

      With the irregular shape of the tank I doubt you'd get a tight enough measurement to extrapolate to volume. There's also baffles, and the fact the truck would have to be sitting just right to be able to get it full without an air bubble.

      The thread isn't at all worthless. The tanks volume is entirely irrelevant. You would NEVER get any sort of accurate number using a tanks volume. The gas pumps readout would be at least 20 times more accurate than your guesstimate on what fractional value volume of your tank you've replaced.

      Did you run it flat empty? I'm Also sure the tanks vary more than the gas pumps do.

      I'll dig up my old pictures, one showing the 17 gallon 99 Sport tank, next to my 93 22 gallon tank.

      I don't recall the actual words I used to describe my many big Fords that I've driven. But I put a bunch of miles on almost all of them, and basically drive every vehicle to near empty. I try to avoid filling often, it saves a little time to not fill up twice at the half way mark, versus once when about empty. So maybe some people see a big gallon number rarely when they find they went too far by accident. I basically carefully gauge how far I can go on each tank of gas, for all cars I drive, and try to get near empty before hunting a gas station.

      So I'm sorry if the various manuals for each car I've owned don't all say they're 22 gallons. But they are all very very close to it. Here's my past cars list for reference;
      1972 Gran Torino, 2dr, 351C-2V, bucket seats, my first car, and my parent's only car bought new.
      1972 Ranchero
      1973 Ranchero
      1986 Crown Vic
      1985 Crown Vic
      1991 Lincoln Mark VII
      1985 Lincoln Mark VII
      1991 Explorer 4dr
      1990 Lincoln Mark VII
      1993 Explorer 4dr
      1991 Lincoln Mark VII
      1995 Crown Vic
      1995 Crown Vic
      1998 Mountaineer
      1999 Explorer 4dr
      1998 Explorer 4dr

      I used to keep a log of all gas fillups and all maintenance, a little book for each in the glove box. I didn't start one for my current 98 Limited, but I will soon. I still have some of those log books, and they show my countless gas amounts, most near 20 gallons, and near 22 in every vehicle. That's my unscientific conclusion that the gas tank is closer to 22 gallons than any manual, experience.

      I found two pictures of the old 93 4dr tank, and my 98 Mercury tank. The steel tank is way longer, but the plastic one has more width internally, and they both hold the same amount. I'll look some more for the 99 Sport tank I bought, I also got the skid plate from a Sport, and the 93 4dr tank is a perfect fit on that short skid plate.

      They do both hold the same amount. I know the picture doesn't make it appear that way, but they do.

      I got the 2003 Explorer Sport (shorty) 2dr 5 speed manual 4.0 v-6, sad thing is this motor gets just a smidge better than the 5.0 and 4.6 v-8s. Fortunatly it is a rwd not 4x4 and it is lighter than a bigger 4 door model. So I average using fingers and toes and a #2 led pencil abt 18-19 MPG Strictly freeway on LONG trips. Gas gauge is not real accurate and I usually do not fill it up, so in town I go for 15 mpg on 5 gallons of gas. I have never run out of gas running 75 miles. Till my sticky notes blew out the window with all my figures. 15 year old suv running on borrowed time for the timing chain. I feel pretty good for that MPG. Gov MPG site says 15 city 20 hwy. NO ONE on the government site ever posted over 19mpg

      I wonder if adding a modified skid plate under the vehicle to smooth out wind underneath would make a difference? I am going to remove the roof rack I never use it.

      ok I found my tips to improve MPG. Make sure brakes/ calipers are not dragging, make sure wheel bearings are lubed well, make sure U joints are lubed every oil change (unless you don't have fittings like mine) make sure rear end in filled properly (in case of 4x4 check transfer case and carrier bearings) change oil and filter often, air filter too. Use good gas, from a reputable dealer (don't we all?), make sure automatic tranny has good fluid properly filled, make sure coolant has proper mix and is filled to proper specs, check tires for proper tire pressure (check when cold and after driving), check alignments front and rear (older Explorers have a solid rear axle, I just found out newer models have the independent units which also need checked, remove excess/un-nessessary weight from vehicle (yes all your tools, jacks, golf clubs, beer coolers, lumber, wife & kids, the dog can stay) you could remove the spare tire too if like mine is dry rotted and flat, also if you don't use the extra seats take them out. Keep windows rolled up as the windows down creates drag. (Going extreme remove the ac and get a different serpentine belt to bypass that, you could try removing the power steering and going with a manual rack and pinion). Another thing when it gets really cold out put a cardboard air damn on the front and see if that improves MPG, but watch you don't overheat. If it is - freezing outside you should be ok, but if it gets above freezing be careful.
