Hi Mike. Keep rebuilding my M38 A1 and it's time for the gasoline pump and the vacuum system for the windshield wipers. I need the military fuel pump (I don't have the core), can you sell me one, with the correct spacer and gasket? Also I need all the lines and parts of the vacuum connection. You have the lines, tees, elbows, etc. to complete the system? Thanks for your attention

Willys Jeep Parts Tech:
We should be able to help with all. Email mike@kaiserwillys.com

I bought you the M38 fuel pump, I have a 4-134 F engine with rear facing front engine plate, and the pump does not fit in the car. Should I install a front facing front engine plate? Or what should I do to fit the pump in the car? Many thanks, Pedro from Spain.

Willys Jeep Parts Tech:
Send mike@kaiserwillys.com some photos of what all you have going on given the unoriginal engine in there.

I have one used, but the black part on the top doesn´t exist. The pump is identical, only with a black part on the top. What is the black piece?

Willys Jeep Parts Tech:
Give us a call and ask for Mike M

I would like a original one! I don´t have core. I Would pay a complete one, but I need original. Do you have a rebuilding kit too?

I dont have the original military pump. how much is the pump if you have to outsource it ?

Is this the only pump that will work with 53 M38A1?

Willys Jeep Parts Tech:
You can use civilian pumps becuase the 4-134 block is same but you would have to re-run your lines to it.

how is the process to send you the pomp and what is the delay to receive it after ? when do you want that i pay ? ragards

Willys Jeep Parts Tech:
Please ship into us. Put CORE on the outside of the box. Put your name and a good phone number inside the box. I'll call you when we get it in. They turn around in approx 3-4 weeks factory rebuilt.

Does the unit have all of the necessary ports for the fording lines?

Willys Jeep Parts Tech:
Yes, that is correct. We need yours in and we can rebuild it. Or if you dont have a core we can source for you.

What fitting will I need to plumb for this pump? Kit available? I have a core to send you for rebuild but does not have any fittings on it. The pump currently installed is an aftermarket but thinking the vacuum lines will be the issue. Might need new vacuum lines as well???

Willys Jeep Parts Tech:
We can add the fittings for you too if you like. They take about 4 weeks to rebuild. Please email mike@kaiserwillys.com or call me toll free. Happy to help out.

What is the correct size spacer to use with this pump?

Willys Jeep Parts Tech:
8329807

Can the fuel pressure be adjusted om these pumps and what is the fuel pressure on them

Willys Jeep Parts Tech:
8329708 is what they originally used. It should be under 4.5 pounds of pressure.

Is the price listed ($149.99) for you to rebuild mine or to buy a rebuilt one?

Willys Jeep Parts Tech:
The price listed is for the rebuild. You send us your old pump and we rebuild the one you send us. Thanks

What is the turn around time on the rebuild?

Willys Jeep Parts Tech:
They typically take 3-4 weeks to rebuild. Thanks

Do I need to buy any gaskets if replacing the fuel pump and fuel pressure regulator?

Willys Jeep Parts Tech:
I would just make sure you put a new gasket from the fuel pump to the block.

I have been ordering parts for the last few years for my rebuild of my m38A1, I'm ready for the fuel lines, new carb and pump, I will reinstall the vac wipers... so my question is, can you put a package together with a volume discount? Last, I do not have cores for the carb and pump, I will need the spacers and long bolts for the fuel/vac pump along with the hoses for the vac wipers.

Are your rebuilt pump parts compatable with todays ethanol fuels

Yes these will be ok for todays fuel and additives. However if ever possible use non-ethanol fuel. It wont gel or collect water like standard pump fuel will.

Willys Tech:
We need your core in for rebuild.
