What Fuel Pump?

[cynosurecivic]

ive been noticing latley that everyone is knocking the walbro fuel pumps. why is this? and whats an alternative to use?

[wootwoot]

a lot of people like walbro's because they are cheap and supposively good. alot of cheap asses buy them, and put them on the car. down the road the fuel pump basically fails and your car goes lean and your engine blows up(turbo applications). this little incident pisses a lot of people off. i recommend bosch and whatever size you need

Walbro's are great pumps, and i have never heard of one going bad for as long as I have been around supras. One of the first upgrades for MKIV and MKIII supras is a walbro fuel pump. Or if power requires it twin walbro fuel pumps to support 700-1000 hp.

I think your claim that people blowing motors attributed to the fuel pump going out is BS

[wootwoot]

should i give you some persons phone numbers?

People have blown motors because of the walbro intank pumps. Running the FMU setup on boost, the pump can't flow enough volume at that high of a fuel pressure...an inline pump would be a better setup. However, they are good pumps if you run an AFC hack or engine management with bigger injectors, and can keep the fuel pressure relatively low.

Well just guessing but i'm thinking that whoever has blown motors on these were cause they were trying to ful all this fuel through the stock line?? Am i correct? Instead of running a dedicated braided stainless like -6an like they should have.

Trying to push more fuel than the line will allow would cause the pump to possibly burn out.

or like dubcac explained.. It was thir own fault for not running a proper fuel system

i dont know the people very personally, just people i talk to. i do know they are ghetto so it is highly predictable they burned out the fuel pump in such a way. good call : )

dubcac is right....a proper fuel system requires all peramiters to be in proportion. Volume vs expediancy is also a very crucial factor. All I can say on the subject is this....personal experience speaks for itself....though some have had good experience with them, some have not, and a 50/50 rating of something so vital to your engine is not a gamble I'll take when thousands of your dollars are on the line. how do you solve the problem, go with another fuel pump...plain and simple. Nos fuel pumps are in my opinion very good. volumetric efficiency is rated at 2% failure in testing....check the nos webpage for more details. thats darn good in my book.

Just, dont think of fuel pumps as the little engine that could...you may not want something that "may" be able to handle your application, you want something that does. you want the that train made of titanium that plows the other off the tracks. no offense to train hobbiests.

I like the way this man thinks...NOS makes great inline fuel pumps.
