Fuel Filters

[ErikSOCAL]

Getting ready to order the rest of my stuff to complete my fuel system. Running a SBC with edelbrock pro flo, ricks tank with in tank walbro 255pump. I'm going to run teflon lines for the supply and have been looking at in line fuel filters between the tank and engine. So far all I've come across are whats in summit, a variety of russell or earls with 40 micron filters. Anyone have input if these are decent filters or recommendations for something better? I found one post on here that recommends to just use a stock style one but I'm not sure how many microns those filter down to.
Right now my system will see about 50-51 psi for fuel pressure and use 3/8 line.
Anyone have a recommendation as far as what materials to use for fuel lines? I'm planning to run all teflon lines. I figure the hardline I would've used would only be along the frame rails so if I just stuck to teflon the lines would follow the factory routing anyways and have at least 2 less interruptions than a hardline + teflon line set up.

Aeromotive makes some nice ones.. 10 micron and 100 micron. I was running a hundred micron pre-filter and a 10 micron after the pump.

Everything that I read suggested a setup like Steve's or a good intank pump sock and 10 micron filter. I'm running an Aeromotive 10 micron. I believe they are sold under other names too.

[ErikSOCAL]

thanks guys, I'll check aeromotive.
do either of you have any recommendations on what to do with the fuel lines. John, I've looked through your website and actually have it saved as a favorite - very cool. Were did you mount the filter? It looks like you have hardline connected right to the engine.

I'm interested in the answers as well. Though I may scavenge some OEM part numbers, just in case.

I have the same Aeromotive setup as Steve's, both -10. The idea is a screen filter before the pump for the big stuff (that could hurt the pump), and an accordian paper element after for the super-fine stuff that could clog the injectors. I've check the pre-filter a few times in 6K miles of operation, and found some debris. The post-filter element still looks new. Maybe I'll throw a new one in every couple years.

Erik,

Thanks for compliment on the website.

I mounted the filter to the mechanical fuel pump block off plate and ran stainless lines most everywhere. The SS lines were a big PITA because I went with 1/2" and 3/8" return. 3/8 supply and return would be much easier. I used braided SS hose at all the flex points.

[ErikSOCAL]

thanks guys, I'm going shopping then at summit! Decided on the teflon lines with an aeromotive in-line fuel filter (thats a pricey bugger but nice!). Its time for this car to leave the garage under its own power!!

[ErikSOCAL]

just a bit of info for anyone shopping around for a 10 micron filter. Discovered that jegs has their own brand for $70 while the aeromotive costs $82. The aeromotive, while in the pictures looked like it came with fittings in the end, doesn't come with them and the jegs has them built in in either -10an or -8an.
I need to return a few parts anyways so I'm going to order the jegs first and see how they look side-by-side.
The billet mount is also cheaper, $33 vs $77 although I may be able to use a large cushion clamp of some sort.
jegs pn 555-15000 for the -8an.
This is exactly why I like paper catalogs.

Have the same kind of setup - 100 micron and 10 mircon - think I like about my 100 micron is - that it has an internal shut off ball value - was about the same price as the Aeromotive piece - fittings were attached. Ball shut off was nice - to shut off the tank to do work - and can always be used as a quick shut so that the car can not run.

The more I know about aftermarket parts the more I like OEM stuff. Use a filter for a late 80s TPI Corvette. It is a 3/8 inlet and outlet. Earl's and other companies make adapters to go from the Saginaw o-ring fittings to -6 AN.

Here is a Wix for about 10 bucks:



It may not be all polished and sexy and all that, but I bet my life on the fact that your injectors will thank you.

I agree with Andrew. With a pair of AN adapters, this is the way I went in addition to a factory style filter sock mounted to the pump inlet in the tank. There are only a couple bazillion fuel injected GM vehicles running around just fine with this exact setup.

The filters are cheap and easily had at any parts outlet. The Wix number is 33481.

I to run the 100 and 10 micron setup. My problem is the 10 micron filter needs to be changed every 1000 to 1500 miles. I can tell when it need changing by the fuel presser and the sound of the pump. Is any one else having this problem?
I would also like to know how many microns a stock filter is.
Thanks Randy

[andrewb70]

I would rather have a clogged filter rather than clogged injectors.

As for the stock filter I have no clue what the rating is. However I suspect its the proper rating for GM vehicles using a high pressure fuel system and Delphi or Bosch injectors.

Dude, you stole my line! The next motor and support systems for the car, which is in the works, is getting a heavy dose of OE parts, and I'm kinda diggin' it.

I'm going to use the Corvette filter/regulator from a '99 car since I'm trying to keep a single line to the front. I'm keeping my fingers crossed but the company I'm dealing with is super comfortable with a 255lph, single 3/8" line, and supercharged 550RWHP.

I like the idea of an easily available, OEM type filter.
Does anyone know what would be the best choice? Are there many real differences, or do they all basically do the same thing?

I've got a 2001 Silverado, so maybe I'll get one for that. Then at least I won't have to worry about having two different filter numbers to think about.

IMO, It would be best to run two of these in parallel. They are somewhat restrictive.

I would like to see some data to back up this statement. This filter has been used, in conjunction with a Walbro 255L/hr pump, to feed a 600HP (flywheel) 496 big block chevy. I suppose if you had a 1000RWHP engine you would need something else, but for the 90% of builds out there, this filter will work just fine.

As for using the 2001 truck filter, I believe it will have the quick disconect style fittings on it. That will make it more difficullt to integrate into your fuel system.

That looks alot like my 97 GMC filter.

You might think that since I changed it over the winter that I'd remember, but I'm not sure. I don't think it used quick disconnects. I'll have to double check.
