|
|
Why is there a Tee in the fuel line on the A1's at the regulator bracket? Was it simply a coupling or was there some secondary purpose?
Also, I have a ell bracket with a 1/4" hole welded to the top of the frame about 12" behind the regulator bracket, is this for a brake line clip?
Thanks,

Hi Mike,
the TEE (128275) is the "fuel supply junction" for the cold weather priming kit, or a gasoline operated heater kit without a extra tank, like the power plant heater kit.
Normaly plugged with plug 143932, no kit is installed.
The other reason is, the longer the fuel line is, so unwieldy it is to install.
So it makes sence to install a TEE to connect two shorter fuel lines, instead of one longer, and it is the easiest/ best place to have a fuel supply branching.
That bracket is to attach the fuel line with a clip.
Take a closer look to the TM's.

That Tee is for a heater kit, but not custom. It is a standard item on the M38A1. This is where they tapped into to get fuel for the gas fired arctic heater kit.

Thanks for the responses!
The gas heater makes perfect sense now and it is easier to deal with the shorter lines...
That's the ell bracket I was asking about...seems like there should have been another one further back on the frame as well, just before the line turns towards the middle of the jeep at the floor riser.

The manual shown is the early version that did not require it because it had its own stand alone fuel tank. I will look for the other.

Sorry Wes,
My fault
I have not had that PM 1571 before.
So I don't know the exact line routing of the primer pump lining.
Now I'm a little bit smarter again.

No worries Frank. That's what books are for. I really have never been able to figure out why the M38 has a service document dedicated entirely to the dash primer and the M38A1 does not. I know that Willys dropped it's attachment early on at the Army's request to reduce procurement costs but apparently they left the provisions for it to be installed in the field.
