1948 CJ-2 F-134 Fuel pump

Post by FWNeitzsche » Fri Jun 07, 2024 6:34 pm

Hello all. I have a fuel pump with the following information on it along with some pictures. I'm trying to get some information on this item. Some of the numbers that are on it is 5592295 and 1538354. Is there a parts breakdown and part numbers anywhere? Does anybody know anything about this. I've found many, many fuel pumps but am unable to find this one. Also, I think I'm missing a piece that goes in the second pictures small orifice. Any information would be greatly appreciated. Thanks

The number for 2a fuel pump is AC manufacturer 153886. It also had a glass bowl with a thumb knob and a bail over the pump body. Old thread but it looks like it is for an M37

The missing piece is the spring that keeps pressure on the diaphragm.

I'm actually looking for the orifice. It disappeared. Anybody have one, or knows where I can get one, or a part number? Thanks.

I'm actually looking for the valve(?) that goes into the empty hole.

I could be wrong. Take the bracket out and see what's under it.

It looks like a filter? One going one way the the other is reversed. I was kinda hoping to get a picture of it.

Two different valve designs. Flip the left one and let's see the other side.

You should have a pencil in a box on the top right of your message to let you edit.

I'm guessing the first picture is the way it is supposed to go. I'll give it a shot. Thanks.

You are correct. Clean the valve seat and place the gaskets.

That is a M38/M38A1 fuel pump. A word of caution is that you need to use a spacer with that arm; or bad thing may happen. I don't know what ad things are but it could range from wrong fuel pressure, damaged fuel pump or damaged cam.

Please refer to this link for a image ( from the ORD-9 manual) with breakdown....it appears that there may only be one value in that location.
