Which fuel pump is the best?

[TOT97]

I'm looking for a fuel pump.
Which brand/part # would be the best for my vehicle?

97 4.0L SOHC (K&N COLD AIR INTAKE, Torqe Master Spark Plugs, Jacobs Spark Plug Wires, Jacobs DIS, SCT Flash)

 

[James909]

Any brand fuel pump would work. I would just stick with name brands for reliability reasons. When I changed my fuel pump I put in a Bosch, it was a little more expensive but came with a lifetime warranty. I recommend spending the extra $10 (I think) to get one with a lifetime warranty.

 

[TOT97]

Thanks James909, where did you buy the pump?
I'm not in the U.S, so I will have to use web.
Do you know which web site has good price?

Is anybody installed high flow pump for less supercharger or turbo?

You could use a walbro GSS342 pump. This is a 255LPH pump so if you decide to go force feed, you'll be ready.

Jakee, I don't need to think about a/f ratio even if I change to 255LPH right?
Does O2 sensor fix a/f ratio?
How does it effect to mileage?
Gas is extremely expensive in Japan right now. ($2/qt)

But I still love to get more power!

No, it shouldn't because you have a regulator in the tank (I believe, please research your year model)

Yes, the o2 sensors correct the a/f but only when in closed loop. When you press the gas pedal about half way, and your truck is warmed up, (running temp) you'll be in open loop and no adjustments are made. Even so, I don't think this is going to change the a/f.

Shouldnt do anything to milleage because of the regulator. In other words, even though it's a higher flowing pump, it's still regulated. If you ever force feed the truck is when it helps. This is just an option I thought I'd throw out there for you. I believe the pump will cost you around 80 bucks.

This pump will not give you more power; it'll only support more power.

 

[James909]

Just an FYI, I think that the regulator for his truck is located at the fuel rail. I believe that Ford moved to the returnless system in '99. Either way that shouldn't effect anything.

$2 a quart for gas!? I'm going to stop complaining now when I have to pay $4.30 a gallon.

 

[TOT97]

Thanks guys!
So, Where can I buy this Walbro GSS342?
Do I need to buy any kit for this?

$4.30/gal would be nice! I wish to be there!

 

[Jakee]

Hold up. So the 97 has a return style system?

 

[James909]

According to this post, yes: http://www.explorerforum.com/forums/showpost.php?p=1372549&postcount=7

 

[TOT97]

I'm sure my "97 has return system.
My explorer is export model, but still it has same system as US model.
Steering wheel is opposite, similar to AU model.

 

[Jakee]

Okay - I don't think the pump I told you will be good; Scratch that one for now.

 

[TOT97]

Well... I found this > http://www.fuel-pumps.net/ford-explorer-1997.html
They have 255 LPH kit for 97 model.

Here is the another web site which they have OE style.
http://www.fuelpumps.com/19972002-f...57z9h307d-f77z9h307ba-f7pz9h307ba-p-1494.html

I think both of them have same OEM part #.
So, might be able to work for my 97??

 

[Jakee]

yes, if you can cross reference both pumps to your OE part number, you should be fine.

Furthermore, walbro is a good pump.

 

[TOT97]

Thanks Jakee, my fuel pump's Ford part # is "F7PZ-9H307-BA".
So, I believe it should be fine. I can't wait to see the new pump!

The GSS342 is made to go into return fuel system vehicles as it is not meant for PWM or variable voltage systems like seen in the electronic returnless systems found in the newer cars these days. This pump will be fine for your 97 if it does indeed have a return fuel system. I know the 98 V8 I worked on a while back had the regular return fuel system on it.

also, the 99(?)-2001 returnless still use a return style pump; I am rocking a GSS342...

Exactly, because they are mechanical returnless versus true electronic returnless. Way back when I had my 2000 5.0 V8 I had to figure that whole fiasco out when I did the blower install on that ol pig.
