I do see one of the Mallory cartrige type fuel fitlers says it's for use between the fuel tank and electric pump and it is 40 microns. Ron

I was told years ago a Micron was one millionth of a inch, not sure if the was a sqaue inch, cubic inch or linear inch Way smaller than the average eyes can see I ended up using a #10 combination fuel shut off and in line fuel fiter that was rated at 80 micron on my Duster between the pump and the gas tank sump, I should have bought the 100 micron size according to Mganafuel My new car will have that size filter rating in a 12 AN in line fuel filter with as much surface area and as long as I can get it I put the Duster together with a BG 500 in line fuel filter, it had a 10 micron fuel filter in it and it did starve the Magnafuuel 275 pump I bought new for that car Live and learn

Cant remember who I called to ask about that filter, but I was told it couldn't handle the output of that black pump. Get a different filter type. Mine is noisy as well, but I got a good deal on it, so for the time being, its on the car.




That's BS. That fram filter is made to go after the pump and can easily handle a black pump discharge volume. All filters are made to go after the pump.
Please don't be one of those geeks who have the pump and filter hanging out the back of your car for everyone to see with the filter between the tank and pump showing everyone you don't know how to plumb a fuel system.
Like Cab said...and you know now.

Use a AN fitting in the tank with a cone shaped stainless strainer built in and no other restrictions before the pump.
Only a strainer with 100 micron screen or courser should be in front of the pump. Even a strainer housing creates turbulence in the fuel flow. And the inlet plumbing to the pump should be larger than the discharge plumbing with very little restrictions(like least amount of 90, 45s and no filters)

The reason pumps are noisy is because they are screaming for help, cavatating there brains out and dieing a slow death. Warmer the weather get's, the more important that the fuel inlet plumbing is right.




Next time I have a question, I wont call anyone but you, because you seem to be a know it all. This kind of an answer is exactly why people don't say anything anymore or offer advice. You have no idea what fuel system is on my car.




Well I seem to be the fastest and quickest guy on this board and have built 6 real fast cars including the fuel systems. How fast have you gone with your fuel system?

I know my way around fuel since I have been in the fuel business for over 30 years now.


And I didn't post anything backwards or wrong above.

It don't matter what kind of car you have, fuel basics apply to every car.

Lastly I don't consider a strainer to be a filter, it's a strainer to protect the pump. The filter which is finer goes after the pump to protect everything after the pump.

OK...you asked. Not going to debate this one either .....but.....micron rating has absolutely nothing to due with flow capabilities when discussing fluids with the viscosity levels of fuel.

Micron rating with filters is referring to particulate size its capable of trapping.....and with fuel the smaller the number the better......and before the pump....no true racing quality level of electric fuel pump will make debris.

Not looking for a rumble....only trying to help. If I wasn't kicked back on vacation right now....I would probably not have bothered as I know this will stir the key board warriors






This post really tells me you do not know fuel pump plumbing. Ever heard of cavitation?

Can you show us where any fuel pump manufacturer says to use a filter with "the smaller the number the better......and before the pump" filter?

They all say strainer or screen element.

I have no interest in persuading anyone of anything. I attempt to clairify my statements are that of my opinion.
My opinion is based on my experience.

I havent spent money on HP in quite some time....largely because I dont care about being the fastest or quickest at the track or on some technical forums. But might I suggest not undermining someone's/anyone's knowledge by how much money they spend.

I will throw this out there....go visit the pro stockers camps and tell anyone of them they are doing it all wrong with their fuel system configurations.

I don't have to visit pro stocks, because all 6 of my cars are were faster than pro stocks. I move more fuel than they do. And I still have 2 cars and 2 BAE hemis 6' behind me right now.

I have the quickest and fastest car on my street.............PERIOD.........AND I plumb my own fuel system all by myself and even read the directions which said; Quote........." Run a filter before the pump no smaller that 100 microns and a 10-40 after" No flat screen filters but a cannister w/more surface area. Oh, and I do drum solos at the request of the ladies when drinkin..........

Hey, same here, but play the bagpipes instead of drums.

I used RobbMc 40's before and after the pump based on his directions.

"40 Micron Filters -
Designed for use as prefilters for gerotor style electric fuel pumps. Also used to filter fuel before it enters the carb."

This thread reminds me of one of my favorite statements over the years........."common sense just ain't all that common"...........LOL!!!

And here is a thought for some........how about check with the company that YOU bought YOUR fuel pump from and see what THEY say............and then refer to first paragraph........LOL!

Have you tried to close a butterfly valve with a centrifugal pump on the suction side when the pump is running?
Cavitation makes both bad sounds and vibrations.
To many bends and other typer of restrictions are bad for most types of pumps. There are som pumps that work, membran, lobe rotor and excenter screw pumps.

my pro stock coffee maker pumps .7 gpm.now if i put the filter before the pump,i will have to invest in toothpics to retrieve the coffee grounds from my teeth.so ill just keep the filter after the pump.and may even send it over to monte to have it plumbed for nitrous to make my mornings even brighter....

Boy do I feel like a geek I think I might just switch the positions and clip my ET from 10.91 to maybe 10.50 I thought I was doing pretty good with a 3600# car and 3.54 gears I'll change it tomorrow and wait unti spring and try it out.
Thanks

Gus, I will betcha you have all the ET and MPH your going to get out of the Carter pump and filter, no matter where you mount that filter All kidding aside those 90 GPH Fram filters do have two ninety degree turns inside of them Changing the location from the inlet to the outlet side of the pump may or any not make any difference to that pump I think those small Carter electric pumps, race or street version, are not rated above 6 lbs of pressure so the suction side is probally not straining real hard to keep the pump in fuel Maybe it is time for a better pump and filter combination
