Hey all, I'm running EFI. What micron filter should I use AFTER the A1000 Aeromotive pump? Have a 100 micron before the pump that will flow 1000 hp. Have another 100 micron filter I was going to use after the pump, but I'm worried about plugging injectors up. I'm using -8 AN line.

550-600 hp 427 sb, may put a 150 nitrous shot on it next year too.

Also, any particular brands?

HUmm....intesting topic, all I use is a carb style filter in the suction side of the pump coming from the tank, been that way for years....some time ago I had all sorts of problems with local fuel supplies and water, but changed stations and no more problems....the two worst down here are BP and Shell, there is a local/regional chain called GATE, that is about the best and cheaper to boot...so I go there and stand fight for a slot in a station with over a dozen pumps...go figger...I have replaced the filter maybe 4x since being here in Florida ten years now....

OK thanks 84, I just ordered a Jegs 10 micron -8An fittings/filter. Unfortunately it was $80, last one I will ever buy though.

If you buy a stainless filter cartridge you can wash it out, then it'll really be the last one you ever buy.

I thought the stainless fillers only came in 100 micron? I have one of those before the pump and another one I won't be using it looks like.

You can get a 45 and 60 micron stainless screen and possible even a little finer from specialty sources like purolator/facet. For a diesel you should really use a 1-2 micron filter but for fuel you don't need that fine. Carbs do fine w/ 60-100, FI is recommended with 10 but the range is something like 10-40 if I'm not mistaken. If you are afraid you'll ruin/clog the injectors, use a 10 micron or finer. You probably won't be able to get a very fine steel filter.

Yep, I think I gave you the solid model for that after I added the crossdrilled hole pattern.

Edit: D'oh! I just looked at it again. Don't think it is the one I modeled. :cheers:

I think I have your model also but it's probably not the one behind the modular wheel in the intro animation. ..then again, could be the one behind the oem wheel model.

Golan makes a fi filter washable with 10 micron ss washable filter. It was marketed ny K&N and Holley at one time too.
I have also seen billet filters on Summit or jegs that have the 10 micron ss filter.

http://www.golanproducts.com/filter-exploded-view.html

I use the element in my edelbrock billet housing on a qjet.
I really dunno about filters and microns all that much, BUT, I have noticed paper filters in Qjet carbs, and others for carb uses, inline glass with replaceable elements....all sorts of stuff....

then I look at the screens in the fuel injectors....and am not all that impressed....

so I just put in that carb style 3/8 line ~2" diameter ~3" long filter in the suction side of my pump/fuel line....never had a problem associated with it....had a few clogged filters allright, due to crappy gas, but never any injector problems....they all been fine, throug the crappy gas and all, no traceable faults....ever...

beeleemee I have had it to over top with weird troubles, but fuel filters have done their job....and they just whatever is done for carbs...not injection...

OK thanks a lot guys. I did order the 10 micron/replaceable -8AN JEGs filter yesterday (paper replaceable element). I'm just worried about plugging an injector and leaning out a cylinder on my new motor, just trying to play it safe.

I was going to use a 100 micron filter before the injectors but then started getting worried. Thanks for the info, probably saved me a rather expensive motor.
