Thread: Ugh! Think my Walbro bit the dust, Under 5k miles.

Check in the engine bay...I don't remember as it has been awhile.

the fuel pump relay is in the main fuel box under the dash. I would check the voltage at the pump. you will want to check the prime voltage and the running voltage.

Walbro pumps might be the worst purchase for your car. Reasons why:

A) you may have a good one that lasts forever and performs just fine, or you may have one that's a pile of crap straight out of the brand new box you bought it in.. It's a 50/50 shot
B) they are inconsistent sometimes across the board
C) just buy an aeromotive 340 stealth and have no worries

but mark. ive heard horrid reliability reports with the 340's too... i have one and im friggin worried!

Yeah im reading that now, Is there an easy way to check voltage at the pump without opening the gas tank? My car smelled for weeks If I dont have to open the tank id rather not.

( again I havent had much time to look yet, been so busy so I maybe asking question on stuff thats common sense. )

You do not have to open the tank, pull the access cover under the rear seat and measure the voltage at the plug.

Please lmk where u heard that from, I swear by these pumps because the failure rate is extremely minimum (as to the fact that I never heard of one failing)

I enjoy hearing other people's feedback on products so we as a community can learn more info on them and get this information back to the manufacturers: this will help with future products etc

I just googled it after seeing some post on some forum... some post even bashed their quality control standards...

Aeromotive 340L's keeps dying on me - evolutionm.net

first link when I googled "aeromotive died pump 340"

I had so many problems with Walbro in numerous cars, i will not buy another.

My old Turbo P10 I ran a GTiR fuel pump. That thing held up to 555cc injectors @3.5bar with 18PSI of boost. If i were to go aftermarket i would pick a bosch unit.
