Does this have a fuel filter in the pump
Willys Jeep Parts Tech.:
I believe there is simple strainer internal but if your worried about bad fuel from your tank i would always run an external filter. You dont want it going into your pump.

Does this model require a spacer? I rebuilt an AC unit with premium kit, has a sliding "foot" that came off first run, was told that's common. I see this unit does not have such. I'd like to be able to run my NOS vacuum wipers. But apprehensive about any further failures.

Jeep cranks and turns over, but after use for 10+ minutes and shutting her down, the Jeep will not turn over. Mechanic thinks the carburetor is so hot the file is vaporizing. Also said the Jeep stared once he opened the carburetor, releasing an air lock. Do you have a picture of this pump installed?

Will this pump work on a 1953 M38A1 F134?
Willys Jeep Parts Tech:
Yes, but you would have to re-run your lines and fitting since your vehicle used a different military pump. But the pump functions the same on the 4-134 F engine.

This fuel pump looks like it has 2 tubes coming out of the bottom. Are these both vacuum lines? If so, I'm guessing that one of them is for the vacuum wipers and the other might be for vacuum assist to the PVC valve piping. Is that correct?
Willys Jeep Parts Tech:
Yes, that is for your vacuum ports typically thru pcv or even a wiper motor.

My engine starts fine, but dies after a second, or two. In trying to isolate the problem, I noticed through the glass bowl that air bubbles are coming into the fuel pump, through the inlet, as it's pumping. Is this normal, or possibly part of the problem?
Willys Jeep Parts Tech:
Sounds like you may have a torn diaphram.

I am replacing a duel action fuel pump and I am hooking it up the same way it was put on. I know this isn’t the best method, but I’m military and it’s how I’m wired to do things, lol. Well, upon reconnecting the lines I noticed “in” on the pump and that’s where the previous owner had a line going towards the carburetor. Isn’t the “in” indicator where you should install the line from the gas tank? Also, what if I did switch the lines and there is no suction? Thank you, Geoie

Should the lever on a new fuel pump move freely, the one I purchased does not move up and down at all
Willys Jeep Parts Tech:
No, they are very hard to actuate by hand. We have to put them in a vise and use a dowel stick to get leverage.

If I have a dual action fuel pump for my 63, CJ5, but am nit currently using the vacuum wipers, can I cap the outlets somehow? Also, is the spacer required?

Dont cap but you would want to port them together. Use a spacer if you have high fuel pressure.
