i replaced mine with a walbro intank. i am running a custom turbo kit. i notice that after 6psi car would run lean. after replacing pump i have not had any problems.

 

[changedman]

is it LOUD ?

 

[MP3skaterNC]

mines alittle louder than stock, but road noise and the radio drown it out.

 

[dominoy2k1]

ehh yeah, you can hear it humming away.

Added an inline (Pierburg). Stock pump couldn't support 5 psi or so. . .started to whine after hard driving.

Pierburg is great, makes a little humm, but nothing major. Allowed me to support 100 psi under boost without fade. Was able to peak about 120 to 130 psi, but couldn't hold it. . .so out went the FMU. . .but the inline fuel pump remains!

i couldnt hear a dump truck driving through a nitro glycerin plant with this open dump tube that every exhaust shop in town refuses to weld into my exhaust...damn podunk, usa.

I'm sorry man, I feel your pain. . .I can't get s*** done in this town either, so I always end up doing it myself. . .learn a lot, but it ain't always pretty.

Guess this means you won't be bothered by the new fuel pump. (One less thing to worry about.) Honestly, it isn't that bad. . .

you think thats bad you shoudl have heard me trying to drive, boost, and listen for the click of the clamp today...it was like 90 degrees i had the windows up, the carpet pulled back, the ecu unhooked and my ear down by the cupholders trying to drive on a deserted road.

???'s tp those with inline or new pumps. Especially if you have a wideband!

How does your car idle and run in normal driving? will the car still maintain a 14.7 AFR while in closed loop?

Which one is better inline or intank??

Also links and prices!

 

[Matthew]

walbro im prolly gonna buy unless ken can get me a price close enough:

I know a shop here locally that can hook you up. Next time you are in town, we can get this done. They have helped me out without question.
