I recently purchased an AC fuel filter with the glass bowl which gets installed at the carburetor, i have a 4GC carb, what kind of fitting is needed to get from the filter to the carburetor, the filter housing is 1/8" NPT on the inlet and outlet and i can't find a 5/16 inverted flare to 1/8"NPT anywhere, is it a Rochester/AC part?
I have the fitting for the inlet side of the filter, its filter to carburetor that i need to figure out, there is a version of it on ebay but it states it is for a Carter carburetor. Maybe i'll take a trip to NAPA after work and see if they have something that may work. I was able to tap 1/8NPT on the inside of a flare nut but it leaves it very thin, i wouldn't trust it for the long run. The circled portion on the photo is what im looking for.
No luck finding the fitting, I used the inlet fitting from a junk carb, drilled it out, tapped to 1/4NPT and put in a 1/4" NPT male bushing with 1/8" NPT female threads inside, should be good to go.
Hi Guys, I lately bought an AC reproduction glass bowl gas clear out from Ecklers. When I established it these days on my rebuilt WCFB carburetor and started the motor it leaks at the bowl to frame seal. I attempted numerous attemps to reposition the bowl and tighten up the stem but the issue nonetheless leaks. Has anyone had the same trouble with those replica gasoline filters? I suppose the trouble is the rubber gasket isn't thick sufficient.
Yes, I had to make a gasket our of thicker "make a gasket" material. My seals were like mush. The ethanol in gas just destroys them. I am thinking paper style not rubber is the key.
