Questions: I have a 1952 Willys Jeep Truck. I recently converted to 12 Volt. I was wondering about the fuel pump. The current one i have was vacuum to run the wipers. Do you have one that doesn't have the Vacuum? Please let me know.
Question By: Michael on Dec 23 2020 9:36 PM
Yes, this pump will work for just fuel on your 4-134 engine. You may just have to rotate the top a bit for clearance for your inlet fitting.

Questions: I purchased a glass topped fuel pump for my 51 M38 a couple months ago. I can’t seem to get it to work consistently, It will bubble and fill sometimes, other times it won’t fill at all? Then it will work perfectly for about a day and then out out nowhere just quit pumping altogether? The M38 floods all the time and is difficult to start. It has a brand new fuel tank, pick up, fuel lines and the Carter YS has been rebuilt, I believe the inconsistent running problem has to do with that fuel pump. The original was a two stage. I want to replace the glass top with the very best fuel pump for the M38. Which one would you recommend as the best and most dependable? Thanks! –Larry Johannes
Question By: Larry on Jun 21 2020 4:33 PM
If it sits up for a long time fuel tends to drain out of the carb. They never will fill up all the way. I would also take the diaphram off and check for any tears and debris that may have gotten into fuel pump from tank as well. Also make sure your fuel lines are away from a heat source.

Questions: I have a 52 CJ3A with an 134L motor. I replaced the leaking fuel pump with a 119238 single action replacement. When we put it in my buddies thought it was wrong that the glass bowl was up instead of down. That, however is the only way it would go in. Since that time a few months ago the jeep has been starting very hard and running terrible uphill or with any load. A local mechanic said "I guarantee that it is upside down and that is the reason it is running badly". How should it be installed? Do I have the wrong fuel pump? Also, I did not use a spacer. Should I get one and add it? Thanks! Ray
Question By: Ray Beisel on Mar 25 2020 2:35 PM
It cannot be installed with glass down. The camshaft lobe pushes the arm up. Give me a call toll free. Happy to try to help you trouble shoot what all is going on with your Willys.

Questions: My Willy's 1947 CJ2A will turn over real well but it does not want to start up. I replaced the spark plugs this summer. The fuel pump looks to be leaking. Think the problem could be the fuel pump? Also, I have a primer handle on the dash board. Do I need to purchase the fuel pump with the primer handle or can I just make do with the fuel pump model without one? Thanks for your help.

Questions: I bought this fuel pump two years ago. Today when starting it for the first time in a few months the fuel pump began leaking around the bowl gasket. I took the bowl off and examined the gasket. No apparent decay. It was off tight from the box when purchased. Why is it leaking? Can the pressure build up between the pump and the carb?

Questions: I have a 1953 M38A1. Will the M38A1 start and run off a electric fuel pump only? A fellow collector told me that it will not start because it needs vacuum from the pump to start. I am an aircraft mechanic and have never heard of such a thing. I had a Dodge M37 that ran just great off a electric pump. Thanks
Question By: Larry Joy on May 27 2017 2:06 PM
An electric doesn't require vacuum. Just make sure you are not putting out more than 4.5 pounds.

Questions: I have a 1965 cj5 Jeep 4cyl with the Hurricane original engine. About 20 years ago I replaced the fuel pump with an aftermarket unit that does not have the glass bowl, unfortunately I discarded the old pump (yes, that was dumb.) It's now time to replace the fuel pump again. The original fuel pump had vacuum wiper ports a glass bowl with a mesh filter built in (very easy to clean and diagnose fuel related problems.) So I'm looking to purchase a new fuel pump w/glass bowl which also has ports for the vacuum wipers. I don't see one on your site. Do you have one? If not, is there a way to add the vacuum wiper parts to the glass bowl style pump that does not have the vacuum wiper ports. I want the vehicle to be as close to original as possible.
Question By: Fred on Apr 18 2017 11:38 PM

Questions: I could not start my GPW (later Willys L134 engine) so I installed the replacement fuel pump. Got it to run for a while (after priming the new Solex carb) off a small auxiliary fuel tank. However, when I connected the fuel line from the gas tank, would run for a few seconds from the priming, but then dies. I rodded out the fuel line (a while ago), fuel is fresh. What else needs to be done? I can't see any fuel in the glass bowl.
Question By: Harry Hoffman on Jun 11 2016 1:45 PM
When you are cold starting you need to pump the pedal just a bit when starting - not enough to flood - and choke it. It should give you the prime you need.

Questions: I replaced my old dual action fuel pump with the glass bowl single action. I have fuel from the tank, through the filter and up to the pump. The pump arm is on top of the cam and I used a spacer. Fuel from the tank is attached on the left with the arrow pointing toward the pump. Line to carb is attached to the right side of the pump with the arrow pointing away. I have pumped the pedal to try and prime and yet I get no fuel through the pump. No gas in the bowl. Nothing! Do you have any thoughts?
Question By: kevin gray on May 17 2014 12:00 AM
I would check the pump for suck/blow on the inlet and outlets by hand in a vice. I would also check to make sure there are no blockages in the tank and plenty of fuel.

Questions: 17701.02 carb calls for 2 psi or less my 62 cj5 dual pump puts out a steady 4.5 psi at idle do i put in an inline regulator ? or do get this spacer that you refer to and if so where do i get one? thanks.
Question By: jim on Jul 20 2013 12:00 AM
You should put out no more than 2.5 pressure. Yes I would get an inline regulator or you can get a good used spacer to cut the pressure down.
Answer By: Willys Tech on Jul 22 2013 12:00 AM
Questions: 1) What is the pressure delivered by this pump? 2) I have a Solex on a 3A. It seems to run well without a pressure regulator. What would be the symptoms of the pressure being too high? 3) I have a lean main jet in my Solex (112), because I live at 6,000ft. If I find that the pump delivers too high of a pressure, is a leaner jet going to have the same effect essentially as a pressure regulator? I find that these inexpensive dial style pressure regulators do not work well consistently."
Question By: Tom on Jun 6 2013 12:00 AM
These pumps will put out appox 2 pounds of pressure. It is recommended that you use the original spacer place between the pump and the block as well. They function just like original. If you are stalling out or leaking or even fouling out plugs you are running with too much pressure or are too rich in the carb.

Your pump you have on there now is unoriginal. The way the bowl is oriented depends on the way the arm is make on the pump where it hits the camshaft. The bowl on this pump goes up like original.

The question I have is as the vehicle runs the gas in the bowl doesn't get much more then just off the bottom of the bowl and over the screen. How high is the gas suppose to get in this bowl? It seems to be running right at a stand still in the garage but before I take it out I just wanted to be sure it's correct and I won't break down.
