What's missing on the fuel vent hose?

[1998rollover]

Found something else the idiot who did my 2002 Sport Trac V8 swap screwed up. Take a look at this photo under the left bed side. A hose to nowhere. Both it and the small pipe that goes into the fill neck lead back to the fuel vapor stuff above the spare tire.

It had become difficult to get gas into the truck, then the other day when it warmed up, I was putting gas in and liquid was spurting out onto the tire. I looked up in there and saw this. Apparently water and slush had been splashed into the hose and froze, plugging it.

I don't know if this fill neck is off the 1998 Mountaineer or the 2002 Explorer, but I suspect that hose is supposed to connect to something.

There are two hoses that lead to the gas filler door. Those go straight to the tank.

There are a couple of different overflow hose sizes. I wonder if your truck has a non matching tank hose size, and they didn't connect the two. Check where the small overflow hose is going from the filler door area.

Above the gas tank is one other small hose, for venting and leads to the charcoal canisters. I'd bet the Sport Trac tank has the same connections at the tank as a 1999-01 Explorer.

That third hose you have there looks out of place. Make sure the other main two are going to the tank itself, right at the back of it. In the picture below is a 99 4dr tank. You can barely see the small hose which comes out the top, and that leads to an aluminum line that goes back above and behind the spare to the charcoal canisters, and that vents above the cross member above my tank.

Is that a pic of a Sport Track or Explorer/Mountaineer frame?

I dropped the spare but couldn't see anything on top of the tank except where the filler hose connects to the down angled part at the back. Going to have to drive it until it's nearly empty so I can drop the tank.

The large hose goes back to the boxes above the tire. Looks like the small hose may too, but it should go to the tank for venting while filling.

If only someone had informed me the idiot was an idiot, and had been in jail for using drugs, and had been fired from every car dealer in the county for being an incompetent mechanic. Some people I mentioned him to while he was doing the swap *knew* stuff about the guy yet didn't bother to tell me until after I got the truck back. Real nice when you ask about a person and nobody tells you anything that would make you go "Oh heck no! I don't want this guy doing the job!". A relative of the guy stood right by and vouched for him, then after he'd screwed all this stuff up had nothing good to say about him. Gee thanks, why didn't you tell me I really didn't want him touching my truck?

Should have done it myself but dad was recovering from a bad case of bacterial pneumonia. The transmission had failed and we were going to swap in a good one (the only one of that type any yard in the western States had at the time) then we got the fool idea of doing the swap from the 98 Mountaineer that we'd rebuilt from it being "lightly rolled". Should have just put the transmission in and sold both trucks.

My plan was to swap all the dash, engine and transmission wiring, the BCM etc from the Mountaineer to the Sport Trac. Then there would have been no problems trying to mix the two together. Still has a problem with an erroneous speed sensor 'malfunction' error that keeps the ABS from working. Both vehicles only use the one speed sensor, on the rear axle, none on the transmission. The speedometer works so the sensor works. What most often happens with the brakes is each time it's started, the ABS light is out and the first or second time the brake pedal is pushed, the ABS pump runs, then the ABS light comes on. The entire ABS unit is new, the one specified for a 1998 AWD Explorer/Mountaineer. The one on the donor was bad, had been for a while. Also have been chasing a problem of it running too rich. Have tracked down and replaced various things, some of which The Idiot broke. What made the most improvement was replacing the EGR valve and pipe. The pipe had a crack in the corrugated section.

Apparently there's nobody else on this forum anywhere near Weiser, Idaho who has done a V8 swap into a 1st gen Sport Trac. If I could come up with a decently priced 2nd Gen V8 Sport Trac with AWD (IIRC the Adrenalin package has AWD) I'd sell this one to a person who likes debugging vehicles and wants a 1st gen with AWD, 302 and four wheel disc brakes.

Look at your truck again, up from behind the rear tire. Find the two hoses at the back of the gas tank. Make sure they are connected firmly there, there should be a worm clamp on each with about an 8mm socket head bolt to tighten with. Those two hoses should be the same two that come out at the filler door.

My truck picture above is my 99 Explorer Limited with the body lifted off.

This thread looks useful http://www.explorerforum.com/forums/index.php?threads/slow-fuel-fill-problem.230950/

There has to be a check valve in there somewhere, and I need to find one of those elbow/pipe parts to poke through the hole in the fender liner. There is a hole to the rear, right by the end of that hose.
