Re: fuel filter??
After. Just dont run a glass one. In the engine compartment is easier to work on also.

Re: fuel filter??
There seem to be differing opinions on this from time to time, some say before and some say after.
I run mine after the fuel pump because I have heard running it before the fuel pump can cause vapor lock. No matter what a metal fuel filter is the best, they tend to hold up better and don't break or melt. Danny |

Re: fuel filter??
Both. I like to run an inline filter between the tank & pump. Then have a filter in the carb inlet. If you have a brand new tank it's not necessary for one from the tank to the pump.

Re: fuel filter??
you can pump sand through a mechanical pump and it won't phase it

Re: fuel filter??
Whats the reasoning behind putting a filter before a electric pump? If you are driving a chevy newer model which has a in tank unit fuel pump it's filter is after the pump.

http://static.summitracing.com/globa...199r7914-2.pdf scroll down to page 2. They actually recommend you run a T fitting with TWO filters before the pump - that just seems like plain overkill. But, a 5 dollar pepboy steel filter is some cheap insurance and keeps its unsightly arse out of my engine bay.

Re: fuel filter??
I wonder if thats just a way to say warranty void in case their pump fails? Extra insurance sorta deal. I read that Thanks. I wouldn't put a dual filter setup unless I was running a drag car or the indy 500 or an airplane. One filter should be plenty on most applications.

Re: fuel filter??
Edelbrock also says my warranty is voided if I don't have a filter before the pump on my TBI system

Re: fuel filter??
Don't most EFI systems still use a "sock" or strainer of some type before the pump? I think as long as the pre-pump filter has little to no restriction, it won't tend to cause vapor-locking or cavitation.
