Fuel filter

Since you are in Tempe,Lopers has the same filter available over the counter save on shipping! I am using a Carter electric P4070 pump and have the smaller version of this between the tank and pump and is working fine.However in the new Summit catalog they caution not to use a paper element filter ahead of an electric pump which these units have :confused: :confused: I had a POS Fram filter previously and the Holley pump sucked the paper into it and fried! which is why I changed filter and pump,so far so good. :) When you buy it get yourself some extra elements to have on hand.

That's the same filter as Fram, but it looks like Summit racing removed the label and is using theirs. I'd bet it's the same filter. Anyways, I'm running that filter and love it. I connected my under the drivers side frame rail on my 56 between the running boards and frame (not the engine/ tranny side where there is too much heat). I'm running a Holley DP but using a mechanical fuel pump and I haven't had any problems (yet!). I like the fact that you can unscrew the bowl, clean it and replace the filter element easily. I would take Double Vision up on his offer! :mwink:

I guess you could be correct to a point. When using one of the in line filters or cartridge type. That type usually goes in the line just before entering the carburator or from the fuel pump to the carb. With the fram, you don't need to do that because it acts similar to a reserve or bath for the gas. The gas flows through this filter and element and does not require any pressure in fuel. In fact, I've seen most application mounted at the rear of the vehicle on the frame near the gas tank. I've never had problems with suction leaks.

Inline Fuel filters

My rule of thumb is Tank then electric fuel pump and your inline fuel filter to carb or fuel injection . Why cause after being laughed at I was drag racing at the local track and yes I did it fuel tank then in line filter then carb sucked the paper into the pump stalled mid track and coasted across finish line.

Here is perhaps a dumb question. If the fuel pump can suck the paper from the filter in, is it possible that it could also push paper past into the carb if mounted after the pump?

I was thinking the same thing tinman. Actually, this is the first I heard of paper coming loose and clogging the fuel system? I guess it would depend on how well your pump "pushes" or "sucks". Boy that didn't sound right? :sweat:

Well Kleen56 I know that an elec pump is better at pushing then pulling fuel which is why you want it close to the tank as possible. So if pulling fuel thru causes paper to go with it I would think that the pushing fuel would be way worse. Maybe someone with first hand knowledge of this can chime in.

Another take on the issue

I would think that the quality of the fuel filter element itself would be the crucial part of the equation. If you try to exceed the flow capacity of the element then any resistance(reduction in flow or pluggage) will suck/push the filter to failure. Perhaps a good ol' North American produced filter cartridge may be the solution- not some pos offshore crap??? How does the flow rating of the pump compare to the flow of the filter? Maybe the capacity isn't compatible?? Also the compatibility of the filter with the fuel used-maybe the moonshine/fuel additives are dissolving the filter :D

Slightly off-topic, but has anyone had any experience with the stainless steel mesh inline filters? Those wouldn't have the same problems with getting pulled into the pump but they are pricey. Do they filter as well?
This is what Summit is recommending for use between the tank and an electric pump,Fram isn't known for quality in manufacturing these days :( there was a quanity of threads on here and many other sites dealing with filter failure issues,I know from personel experience I will NEVER purchase their products again!

I picked up one of these on Ebay for $30 new, has several size micron mesh screens available. Placed it between electric pump & tank, & a smaller micron filter at carb.
