For those of you running a Holley or something like it, What are you using to pre filter the Pump? I'm running 1/2" lines and I'm using a Inline Fuel Filter. I might be getting a 1000miles out of it. They seem to clog up quick and at $9 a peice, its gettiing expensive for a truck I dont drive often.


What other options do I have?

Thanks

You need to be real careful running a fuel filter on a pump's inlet. Any restriction on the suction side causes cavitation, which is a pump killer. The best idea is to run a coarse, screen filter on the inlet (to trap large junk) and a fine micron filter on the pressure side. Or you could go and get an AD or FASS and just be done with it...

If your pluging the filter at around 1000 miles, I'd say you might need to drop your tank and clean it out. sounds like you have alot of dirt in your tank.

use the same suction filter that the fass pump only uses napa 3270. it is a screen instead of a paper filter element.

Fleetguart FF-5079 for about $7. Had the strainer on about 35,000 miles with no problems yet....

Thanks for the input guys. My inline filter looks the same. But I bet its different inside.

I'll give these a shot.

I cut open my "filter" tonight. It is in fact a strainer. I'll have to do some checking on my pump then.

Thanks guys

I just run the stock fuel filter on my truck, and my carter has a mesh screen in the inlet side of it from the factory. Works pretty well. I can usually tell my fuel filter is starting to get dirty after 5 thousand miles or so though.

I don't think you would need any kind of pre-filter as long as you are pulling fuel through the factory module. The pickup module has a fine enough membrane that anything that passes will not be large enough to harm the pump. If you use a draw straw setup, I'd use a 120 micron mesh screen water seperator.

I run a permacool (http://perma-cool.com/Catalog/Cat_page26.html) fuel filter water seperator right after the tank. Filters at 2 micron. I have a fuel pressure gauge at the vp44.
