Question By: George Mirtsos on Jul 22 2016 6:50 PM
You can put the spacer back on there. You may have to rotate the diaphragm for clearance.

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: Is the fuel operated by a cam lobe or push rod?

The fuel pump arm rides on your lobe of your camshaft.

It will work but on the M38 you may have to rotate the diaphram for any clearance issues.

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.
Answer By: Willys Tech on May 19 2014 12:00 AM
Questions: I have a 63 willys here in my shop and was wondering if there is a replacement screen for the bowl style fuel pump
Question By: brandon on Apr 18 2014 12:00 AM
That would only be available used. Or this fuel pump above will have a new one in it.

Questions: I rebuilt my carb in 56 willys and now cannot get fuel to carb. Did I do something wrong in rebuild? Or does fuel pump need to be primed somehow?
Question By: Anonymous on Nov 2 2013 12:00 AM
You should be able to bench test it for suck and blow. You may want to check your tank for any blockages as well.

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.

Questions: Just purchased the #119238 fuel pump. My 1951 Cj3a has a pump on with a spacer between the block and pump. Old pump is not duel action and does not have a glass bowl. Do I need this spacer with this new pump? Reviewed an article stating the 3a original pump needed the spacer. If changed to a single action do not need spacer. Is this the original type for a 1951 3a? Thanks
Question By: kris kinsey on Mar 1 2013 12:00 AM
Yes I would put the spacer back on there. They are good to cut down on fuel pressure.

Questions: I just bought the new single action to replace the dual action on my 55 cj. I cant install the new pump because the front engine mount blocks the fuel line. I thought i would go with electric wipers and didnt need the dual.is the dual the only choice? Thanks.
Question By: chuck on Oct 19 2012 12:00 AM
You can rotate the diaphram on it and just use a 90 degree fitting on it. It should work fine for you.

Questions: Have 1948 cj2a, L134 engine, have mechanical fuel pump on with the metal bowl down, it should be up? I have in install incorrectly? Went to town and it died, would only start with choke all the way out. Has been running fine up till today for about a year. Was recommened that i put new fuel pump and a electric one as well. What is your recommendation? Thank you in advance.
Question By: Tom on Aug 25 2012 12:00 AM
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.
Answer By: Willys Tech on Aug 27 2012 12:00 AM
Questions: hi - bought a fuel pump from here about a year ago and it has the bowl on the top - do you have one that has the bowl on the bottom - that is what my 1953 cj3 originally had. Thanks, Kerry Wenzl.
Question By: Kerry on Aug 18 2012 12:00 AM
They were originally bowl on top. This is proper for your vehicle.

Questions: I have a 1961 willys cj3b. The fuel pump works but it is leaking fuel from a small hole in the center of the pump. it is a dual action pump. Is it something I can repair or does it need replacing. If needs replacing will the single action work? I have electric wiper motors now and don't need the vacuum
Question By: dan on Aug 10 2012 12:00 AM
Sounds like it could be a bad diaphram in your old pump. If you are running electric wipers then this one should work just fine.

Questions: 1950 Willys Jeepster 4-134 F Head, thought we just ran out of gas filled her up would not start, primed carb runs until prime is out. blew out all the fuel lines and cleaned the fuel pump screen. fuel pump is a single action with glass bowl seems to work because it fills up with gas but does bubble. cannot get fuel to carb. do I need a new fuel pump the one I have was new in 2009?
Question By: Jerry on Jun 30 2012 12:00 AM
Sounds like a stuck valve or bad diaphram but its hard to say. This fuel pump will solve your problem.

Question By: Anonymous on Apr 20 2012 12:00 AM
When you start make sure to pump the pedal a few times to get the fuel going. If you let the vehicle sit up it can be alittle hard to start.

Answer By: Willys Tech on Jan 10 2011 12:00 AM
Questions: I bought the fuel pump #119238 for my 1945 gpw. I installed it and the jeep started right up with a little primimg to the carb. 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.
Question By: Phil Galvano on Nov 4 2010 12:00 AM
It doesnt fill up all the way typically. The bowl will fill up alittle more or less depending on speed/pressure. Sounds like your good to go.
Answer By: Willys Tech on Nov 8 2010 12:00 AM
