The Stovebolt Site Forums The Shop Area Engine Shop fuel filter placement

Hello folks, I've got a glass bowl in-line fuel filter I'd like to put on my '46, 216, Carter w-1 carburetor. I've seen people put these next to the carburetor, but shouldn't it be down below connected to the fuel pump? I'd like to put it up on top next to the carb where I can see it, but when I'd change the filter, gas would drip on the manifold. Anybody know where it was originally?

Swampcat,

Don't know about where it was mounted on Art Deco trucks but on Advance Design trucks (47nd-55st) it was mounted into the carburetor inlet. This was not a stock item but was a Chevrolet accessory (AC brand). The mounting location is shown in Advance Design Accessory Installation Manuals.

You are right: some people installed them on the fuel pump outlet in order to keep gas drips off the manifolds.

Mine was on the fuel pump inlet, I assume to keep gunk out of the fuel pump.

Mine had a glass bowl filter built in on the top of the fuel pump, which kept the gunk out of the pump. If you read the fine print on the fuel pump waranty, you will find that the waranty is no good unless there is a filter in line before the pump.

Thanks for the info, guys! Jacques

If the filter is supposed to be before the pump how come all those GM cars and trucks from the 50-70's had the little bronze filter in the carb inlet?Was there another filter in those cars and trucks before the pump?

NOPE. Which is why I was surprised to find one built into the fuel pump. As near as I could tell, it came with the truck. I don't have a parts catalog to see what was offered.

Speaking of fuel filters. Where could I find (or make if I have to) a GASKET for the glass bowl type fuel filter that is mounted on the inlet side of the fuelpump? Thanks

I have filters on both sides of my fuel pump, but not the old glass bowl style.

Terry, I went to my local auto parts store yesterday to find a replacement filter element for the AC glass bowl filter, the gasket (rubber-like seal at the top of the bowl) is still good. When I told Harry Potter's twin sister behind the counter what I was looking for, she immediately led me to "Old man Cliff" sitting behind a desk in a cubicle raised a couple of feet off the floor, where he looked like he was master of all he could see. I thought, "Ah-haa, Old man Cliff probably has one of those rare gems in his desk drawer". Cliff led me to a shelf and picked up something plastic and held it in front of my face and asked, "do ya think this'll fit on your air compressor"? I told him it looked a little big and thanked him for his help and as I turned to leave he said, "I can't find a thing around here since Harry Potter's twin sister started working here". At the door, another patron provided me with the information that he saw a new one, element and all at the IH dealership in town. I'll try that one tomorrow. Best regards, Jacques

I think the NAPA part number for the fuel filter for the AC glass bowl filter is 3034 (NAPA Gold Fuel Filter).

The box contains a cylindrical, paper filter element and the rubber seal for between the bowl and housing.

Go back in time(before our throw-away society) a few years and you will find that those glass bowls you speak of had "pumice" filters in them and they were mounted just in front of the carb. Didn't need to throw away a filter, just empty the water and gunk out of the bowl and clean and spray out the pumice filter and you were good to go again. That bowl lets water and rust and dirt settle in it and you can see when it needs cleaned out. Find one with the pumice stone and you don't have to keep buying filters. I know, You just can't stand the thought of not having something to throw away.-LOL OH!! And those bowls were called "Settling bowls" because they let the water and junk settle out of the gas.

Oly,

Thanks for the info on the pumice filters. I have one that I did not throw away because it looked too nice (and interesting). I will now use it.

Do you know a technique for cleaning one? Or, since it is a settling bowl, it is just a matter of cleaning the sediment/water from the bowl?

Thanks,
Tim

Thanks for the info one and all. My filter has what looks like a cylinder formed of loose brass granules that have been heated and stuck together. There is a coil spring that holds it up against the top. I clean the filter and the settlin bowl in (solvent)and reinstall it.
Cheers

Tim, how'd you get that part number? I went to the store this morning with the number and got the filter element I needed. Thanks for the help, Jacques
