Gas filter

I am running a Mallory Comp Pump series 140 electric fuel pump. I am using a Fram HPG-1 fuel filter with a 10 micron paper element. I took out the filter element and found globs of something that looks like caramel color spray foam. The globs are piled up along the inside bottom edge of the filter. When I rub the stuff between my fingers it turns a powder. Has anyone experience this? Can anyone recommed a filter with a stainless steel element 40 microns or lower? I am not seeing anything in the tank (as best I can see in the tank) that looks like this stuff. I think I read somewhere that a steel element is better since the paper element sometimes come apart. Thank you.

Russell Performance has a billet filter that will stand up to the pressures of modern fuel pumps for fuel injection.

I'm using this 6" filter with stainless element from Speedway. They also have a 12" long version.



.....and installed on the back of the engine, using some 2" rings and with -6 line and fittings



With the "new" ethanol gas - who knows what else has been added

Speaking of ethanol, here's a marine carb that's been running ethanol 'enriched' gas.

Gas filter

I should have mention that my filter is between the gas tank and the electric fuel pump. It is a canister type and is 2 3/4" diameter and 2 1/2" tall. What's the deal with the ethanol. Does it contain water? I have a 750 Holley carb, not fuel injection.

I had the same problem with a Fram filter their quality is garbage,the paper element fried a new Red pump in less than 2 hours run time,Summit now has a warning in the catalogs about paper filters and electric pumps,seek out a stainless element filter and you should be OK.

I don't generally use any Fram filters any longer based on Bob is the Oil Guy website reviews of oil filters. I just "carry over" his reviews to whatever filters I need, air, oil or fuel. Fram, in this case for oil has poor build quality, tho I do occasionally use an air filter.

Just for the heluvit, I did a look at fuel filter reviews and a couple sites, guys were complaining about restricted gas flow causing starvation and performance problems.

Too bad, Fram products used to be the filters of choice for me and many others, now, I believe many are made in China with poor quality manufacturing. For me and my Fords, I'm using all Motorcrafts where possible, Purolators if not and the Speedway SS for my '31's gas.

They say if you have a filter ahead of the electric fuel pump (between tank and pump) use a steel filter -- if after the pump a paper filter is OK.
The rule is: suck steel, push paper.

That's odd. There is no pressure between the tank and the pump.

Having said that, I pillaged the auto store to find two filters that would work for me. Between the pump and the tank I use a big filter for a carb with 3/8" barbs on it. After the pump I'm using a stock fox mustang filter.

If the big filter with barbs has a stainless steel or sintered bronze element inside (and not a paper element) you should be good to go.

Fuel filter

I think I am going to go with an Aeromotive 40 micron filter with a stainless steel element that is good for gas, alcohol, E85 and methanol. The instruction I got with my Mallory Comp. Series 140 electric pump calls for "mininum 40 micron filter between the gas tank and fuel pump. Does that mean I could go up to say 100 microns or does it mean I can go down to say 10 microns? I am thinking that if you get much below 40 microns on the sucking side you may be starving the pump. Thanks.

I'm sure it means the number should not be less than 40. Aeromotive in fact recommends 100 (minimum number) ahead of its fuel pumps to avoid fuel starvation but the Mallory sounds like 40 is OK.

Fuel filter

Has anyone tried a ROBBMc Performance 40 or 100 micron 5" long or 3 3/16" long fuel filter between fuel tank and electric pump? They use a Sintered metal element and are much cheaper than an Aeromotive filter. Thanks.

I have heard the Russell 40 micron filter which has a reusable (cleanable) sintered bronze element is OK also -- available from Summit for about $12.
