What fuel pump?

[Pman73]

What high performance fuel pump should i get for my 95 GT? Any help would be appreciated

 

[Black1987]

What mods are trying to support?

 

[Pman73]

I have headers, competition cam, 3" exhaust with X-pipe, GT 40 heads

 

[General karthief]

155lph or 190lph.

 

[Mustang5L5]

155lph or 190lph.

I second this

 

[Noobz347]

I will add that the "high pressure" variant of any Walbro pump should be used when dealing with Mustangs and potential upgrades.

190lph high pressure unless you got mods planned for the [very] near future that dictate more. Going too big is not an ideal situation either and the reasons are debatable.

Now is the time he tells us he has a compound boosted drag car he found in his dad's barn!
just pushing your leg!

That runs on E85

 

[Pman73]

Lol no just heads, cam and cai, x-pipe. Hoping to do more mods soon but nothing major, gears etc

I ran the car out of gas now it wont start, changed filter but still no gas, i can hear the pump run when i turn the key over but i know that doesn't mean its pumping, im assuming i burned up the pump when i ran it out of gas, its a bbk high pressure

 

[General karthief]

Have you checked fuel pressure?

 

[TOOLOW91]

Like mentioned . Check the fuel pressure .

3 inch exhaust all the way through ? Someone make the x pipe and stuff for you ? They don’t just sell 3 inch and that’s a lot of exhaust for a GT40 hci car .

I second the given recomendations but just that it must be a walboro .

 

[General karthief]

Yeah that 3" exhaust does not provide enough ' back pressure '.

Stop Saying Car Exhausts Need Back Pressure

His initial analogy where he's varying atmospheric pressure, doesn't include the effect on the inlet but the rest of this is very good. What he's describing is a "Tuned Exhaust". Something that a few of us have talked about at length but keeps still crops up a few times a year. View...

As for the pump, IMO only 2 make sense.
A 155lph for a NA build (it will go close to 500rwhp all motor)
Or a HP 255 for supercharged build.

Never mentioned it was just surpised he had 3 inch all the way through . It’s quite uncommon as I had searched around for a while which is why no one seems to really make much . We built my x and flow tubes to the mufflers and used the Flowmaster tails I had .

I would just go with a 190lph

I was joking about the back pressure thing.

 

[91GTstroked]

Hmm. My car has h/c/I 306. Previous owners say it has a 255lph fuel pump. I was going to replace it with the same pump.

In Theroy is it’s over kill . In real life I’d put same pump back in

All of the diesel Mustangs came with it from the factory.
