So all of these vendors are selling the Walboro 255 lph fuel pump but no one can tell me how much the stock pump will flow??? I've searched the internet and found nothing. Anybody know how much flow or even the pump part number and manufacturer???

 

there was a htread on it a longtime ago the stock pump isent that bad it is supposed to be on the same playing field as a walbro 255 hows the car run with the zzp cams

 

i forget how you know i have zzp cams. i think i remember we might have talked about it. i love it. they kick on real nice around 4200rpm. im going turbo (Garrett GT3076) and they should complement the turbo nicely. just bought a LSD trans and looking to find wider wheel for wider tires...

 

u have the stage1 cams dont you u ever get it on the dyno and y go turbo push that tvs

 

Stock pump Outflows a walbro 255

 

Hey op if youre selling the tvs I'm interested in buying

 

i did push that TVS as far as 93 octane. i had a 2.7 on it and was hitting boost bypass due to heat. then i dropped the boost with a 2.8 and i was fine. and that was with a dual pass, front mount, and 70/30 meth

already sold

 

I am hear to revive for my own personal benefit... haha

I've used the search function and this is all I stumble upon...
so maybe someone can give the answer of the question above. "what is the stock fuel pump flow rate?"
or point me to the correct thread that I cannot seem to find.

I am having a fuel pump issue and therefore have decided to replace it.... now I need to figure out if i should upgrade to an AEM/walbro or stick with the stock fuel pump...

eventually I will be stage 3 2.8 pulley 60# injectors.... thats the future.

 

the stock pump will more then easily handle that even on e but you will need 80s

 

Thanks

I ended up finding it... I believe we have the Bosch 044 inline FP... Which is a 300lph flow... Took several hours but I found it.

 

No that is wrong. The stock fuel pump is not inline and is not the bosch 044. It flows about 225 lph and is an in tank model.

 

good to know. thanks Josh.
