I have an AC single action fuel pump with glass bowl and primer lever. I purchased a rebuild kit (A9293). Is there a video or technical sheet showing how to remove the old diaphram and replace it with the new one? Thank you.

Willys Jeep Parts Tech:
There isnt, but give us a call and we can try to help you.

Are the in and out valves common or specific to in and out? Thank you.

Willys Jeep Parts Tech:
I do believe they interchange but will need to double check.

Is there a way to tell the difference between the single and dual action pumps without taking it apart?

Willys Jeep Parts Tech:
2 ports v. 4 ports

Does this include the gasket or the spacer to the engine? It is hard to see from the picture

Willys Jeep Parts Tech:

I have a 1956 CJ5 with a dual action pump but I have electric wipers so I don't need the vacuum part of the pump. Will one of the single action kits work for just the fuel pump section of this dual action pumps?

Willys Jeep Parts Tech:
This is for the original single action pumps only.

Is there an instruction sheet or diagram that I can use to understand how the large spring retainer cap (rubber) and washer is secured to the shaft of the pump diaphragm. The black rubber cup slips over the end of the shaft but has no way to keep it from slipping back off.

Willys Jeep Parts Tech:
We should be able to scan in a breakout and email it to you. Please email

Do you sell the rubber gasket that has the holes in it and goes between the bottom and top of the pump by itself?

Willys Jeep Parts Tech:
Sorry, it is part of the kit only.

I have a 1953 m38a1 with a Carter MO 732 fuel pump. Will this kit work?

Willys Jeep Parts Tech:
If you can please email an image of your pump and we can help.

I have a 1952 Willys Jeep Pickup with the F-134 Engine. Ii recently bought this kit not realizing mine is a dual action fuel pump. Is there a way I can return this and get the kit needed for my Dual Fuel Pump? Or am I going to have to buy the whole Fuel Pump assembly? The only thing that went bad is the Diaphragm.

Willys Jeep Parts Tech:
Yes, never a problem to return. Please call us toll free. Happy to help out. Thanks!

Will this kit work with the original fuel pump on my ‘53 M38a1?

Willys Jeep Parts Tech:
No, the orignal M38A1 was a dual action pump. See part number: MFUELPUMP

Do I have the correct fuel pump? On the underside, it appears to have raised letters AC and the numbers 1523039. Numbers are worn, blurry, and hard to read.

Willys Jeep Parts Tech:
As long as you have a 4 cylinder engine and the fuel pump is a single action pump, this will be the correct one for you.

I have a Canox welder with a Kaiser engine serial number R4J-445827 I would prefer to put a complete gas pump the models that look like the original on the welder no.119239,119238 or the kit a-9293 .The number on the original pump MO-732. What years is that motor and what pump should I put to replace the other one? Thhank you for the information,and I would sure appreciate the info. so you could send me the pump.

Willys Jeep Parts Tech:
If you have the 4-134 engine these pumps would work for you. They are fuel only. If you need a vacuum you would run it off the base of the carb.

Is the pump Diaphragm as thick as the original? The original was heavy as a inner tube. Just trying to decide to rebuild or replace. Thanks for the info

Willys Jeep Parts Tech:
Yes, this kit includes parts that match to the original parts. Thanks

Will the diaphragm in this kit withstand gasoline that has ethanol in it?

Willys Jeep Parts Tech:
Yes, this would be ok for modern fuel.

Is there a rebuild kit for dual action fuel pumps? 1951 3A

Willys Tech:
Sorry, these are only available complete.
