Need a small part

[jakenoklahoma]

Cleaning up and getting my fuel pump ready to put back on my 51. I need the round cork gasket that the glass fuel bowl sits on.

They are shown on the NAPA Online web site so you can probably get them from your local NAPA store. However there appears to be three different gaskets depending on your fuel pump. So you might want to take in the pump and/or the bowl or old gasket to match up. See: http://www.ply33.com/Parts/group14#14-80-05

go look in the tractor parts section at your local farm and fleet. there are usually sediment bowl rebuild kits with these cork gaskets and everything.

hijacking this thread. Is there supposed to be a filter in the bowl? If so, does anyone have a part number for it? They did not have one at the local auto parts store we got the pump from, so I put a filter in the line.

no filter in the bowl, but there is supposed to be a brass screen at the top, in the pump.

There is a screen at the top of the bowl. The bowl and screen are the filter. I think the idea is that dirt will settle out. That is all that my car has ever had on it and it seems to be sufficient. I guess if your tank was full of gunk you might need more but I haven't had a problem.

[BulldogTom]

OK. I think I will run a couple of tanks of gas with the inline filter I put on it. We drained the gas tank but did not clean it out, so just to be careful I will leave the filter on for a while, then remove it later.

Thanks for letting me in on this thread.

I never understood why there was a need for a glass bowl on the fuel pump and a separate glass bowl in front of the carb. Why not put the filter in the fuel pump glass, run a line straight to the carb, and be done with it? Not to mention the jostling the carb filter bowl took on rough roads, makes me wonder how many of those brass fittings from the filter head to the carb split in two from the vibration. Evidently, fuel storage & transfer was not a clean process back in the day because of this redundant filtration setup. However, I've seen many an old Farmall that had a sediment bowl below the gas tank that fed the carb with no fuel filter in sight.

I've been tempted to eliminate the carb filter housing and put a filter in the fuel pump, but I don't have enough smarts to know how this will affect the carburetor. During engine idle operation, I've seen bubbles percolate in intervals inside the carb filter bowl, as the carb float chamber empties and the fuel pump shifts from bypass to pumping more fuel into the filter bowl. I'm a-thinkin' the carb filter housing is doubling as a reservoir for the carb float chamber, so that during an instantaneous wide open throttle operation, ample fuel can dump into the carb float chamber with minimal lag time in re-filling, kinda like having the reservoir on a residential water heater. If I install an electric fuel pump, I wonder if this carb filter bowl will be obsolete. I recall later Chrysler carb setups that had engine mounted mechanical or electric fuel pumps with no sediment bowl and an in-line fuel filter before the carb, with a return line back to the fuel tank. So I reckon it depends on how much the individual wants to modernize their fuel system to wring out as much performance as that flathead can muster.

The glass bowls served as a water trap also. There were fine screen filters in the bowls between the gasket and the glass bowl and both can be found at farm equipment dealerships and possibly at power equipment dealrships. The old Farmalls often had a really fine filter on the brass fitting that went into the carb. It was often neglected, often not cleaned, often not even known about and often destroyed when removed.

I was at Tractor Supply today buying feed and looked around teh tractor parts section. Sure enough, I found a screen & gasket set for an Allis Chalmers tractor that fit. The screen needed center hole made a bit bigger, but it's all done now. Tractor Supply Co Part Number 0237055
