car is all stoc kas far as fuel. I notice at sharp turns car dies for split second so I figure I need to replace fuel pump. I am sure it is the original pump.

what pump do I need? i dont want to overdue it. I figured the Walbro was the way to go. I bought a pump local for my last car and it was more than the Walbro but I needed it right then

I can afford to waite for it this time so I will buy it online.

if its an NA you dotn need a pump, if its a turbo get the 255 lph.

also on left turns thats not your pump its the sock, the filter directly connected to pump in the tank.

gentlejax2

what do I do about the sock? why not replace the pump anyway before it dies.

I knew it wasnt the pump directly but if I got do go into the tank might as well update the pump.

so what do I need to do about the sock?

gentlejax2

my wifes Focus had the same problem and had to get fixed 2 times. luckily it was under waranty

gentlejax2

now that I read your whole post again.... I didnt think I could just buy the filter but If I got to do that Iwant to replace the pump too...

so what pump? yes it is a NA. I just dont want to get too much of a pump and cause other problems. I know there are a 190 & 255

gentlejax2

also, where is the cheapest place to get one?

gergrx7

you DONT NEED A WALBRO its WAY to much for an NA. call up mazda adn tell them you need a fuel filter thats in the tank. if you want you can get a new pump also. but i doubt you need one.

You can take out the fuel pump and clean the filter yourself...

What... heh.. thats like saying since the lightbulb is out, the power to the whole city must have gone out. Don't jump to conclusions...

Replace your fuel filter before replacing your pump.

If your car is an n/a, the walboro 255 is going to run your n/a so rich you'll lose alot of power. Bottom line is with a walboro 255, you'll need aftermarket-fuel management to shorten the injector widths to cope with the raised fuel flow.

Hell, it could even by a short in the harness somewhere that when you go around a sharp corner, the pump cuts out.


Oh, one more thing. If the tank has never been cleaned, you should remove the fuel pump and de-gunkify the intank fuel filter sock. It can get gunked and deprive the pump of fuel on turns.

can i get some help on what pump i will need i might buy a s5 t2 and it has fcon with the fcd intake exhaust greddy bov and a couple other things but its on stock fuel system my goal is 400-450 hp what fuel pump should i get i was thinkin the walbro 255 would be good would this be good to be used with the mods it got donme to it now and would that pump handle 450 hp

Kenteth

i think it handles to about 400, but i can't remember speficialy...

thanks kenteth do you think that would be the pump i should get with these mods that are already done to the car and also upgrade all 4 injectors with 720's then i could run 12 psi right on the turbo

Kenteth

to be honest that ones over my head--- I'm an n/a guy I'm not familiar enough with fuel consumption over 250hp to be making advice on it.

alwayssideways

im not sure but i think alot of guys stay with their 550 leads and swap out the secondaries to 720. .

to reiterate .. DO NOT PUT A WALPRO ON A NA. Especially if its stock or damn near stock. You will burn and waste more gas then you want to. clean your filter. if that doesnt solve the problem . maybe do the fuel pump rewire or something. just dont do the walpro on a na. trust me

sudseh

walbro does have a nice 190lph(not sure on units) pump that looks decent for solid fuel delivery... fwiw

Kenteth

probably a quarter the price of a dealer/distro oem stocker too... good info. Anyone know of an online walboro distro that might have them?

gentlejax2

RX7Store.net has the 190 Walbro. that is one of the options.

I will clean and drain the tank and clean the filter
