Fuel Pump for 1961 CJ5

I finaly took my CJ5 out on trails for the first time (well I attempted to ). Unfortunately it started acting up and I was never able to test it out. Anyways it looks like the fuel pump is the problem. It is not keeping the fuel filter full and I can see lots air bubbles but when it cools down it's ok no bubbles :?. My question is do you guys recommend going with an electric fuel pump or getting a replacement mechanical pump like the original?

Thanks,

 

I will take some pictures of the fuel line routing after work today and post them.

Edited:
Here is a picture of the engine compartment I just found in my imageshack library. I will take a better one later when I get home.

 

nothing more should be needed

 

My fuel filter is clear plastic so I can see the fuel as it passes and fill up the filter.
When the Jeep stalled I noticed the filter was completely emptly and every time I cranked it up I could see more bubbles than fuel. I would leave it to cool down and then it would fill up very rapidly. If I attempt to crank it without letting it cool down all the way I would see the bubbles and the filter would never fill up.

I noticed this by accident because when it stalled the first time and after many attempts to get it started I decided to ride back to the entrance to get my towvehicle. It took me about 20 min to get back. After pushing the Jeep and hooking it up to the towbar I decided to look one more time in the engine compartment. The filter was full of fuel by that time so I tried to crank it and wala it cranked. 20 to 30 min later same thing and I noticed the bubbles at that time.

 

here are additional pictures of my fuel delivery.

 

My filter is between the pump and the gastank, mounted over by the fenderwell below my horns. Clear see through. It's always empy looking while the '60 is running. Yours - however -
is between the pump and the carb, and should IHO be mostly full under running conditions.

You may have pick-up issues in the tank, where it is clogging up the line after 1/2 hour of running time. Some one put ping-pong balls in your gas tank?

 

I thought so too..
but now I don't think so looking at that outlet
maybe a pump output/pressure check is in order ?
along with Glenn's suggestion or others saying to check the fuel lines, etc.

 

Make sure you don't have a clogged vent at the fuel tank. That kept my A1 from running at all. I just happened to crack the cap while it was running and all of a sudden everything smoothed out. The vent was clogged causeing a vacuum in the tank the pump could not overcome.

 

Ok here is the history on it as far as I know it .
I bought it back in April this year. The JEEP according to the previous owner had not run since Hurricane Wilma hit South Florida back in Oct 2005 when he used it for the last time to help clear debree. Previously to that he used it to ride at Tellico, NC. When I bought it in April I noticed no fuel was getting up to the carb. I then found that it was the actual carb float valve that was stuck closed therefore not letting the pump push fuel up the line. I rebuilt the Carter YF myself and was able to start the engine. Ever since then I have been starting it and leaving idle on a weekly basis.
I changed the filter and got rid of the old fuel.
Yes this was my first time ever driving it even thought I have had it idle since I fixed the carb back in April /May. The fuel pump looks like it has been there since day one because it looks very old just like the Carb. Even thought this JEEP has electric wipers the fuel pump is a vacume pump also. This JEEP does not have the original under seat gas tank instead the previous owner had an aluminum tank custom made to fit up against the back inside tub. The fuel pickup on the tank is actually from the bottom of it so I would guess the weigh of the fuel may help the pump and I also verified the vent on the cap was not clogged. Not sure if the length of the fuel line has anything to do with it? Eventually I will get a new original style tank when I can afford one, but I also need to look at how the seats mount because what it currently has is not original, I will leave that for another topic.
I replaced all rubber fuel hoses but not the metal piping.
So far I have not seen any fuel leaking out of the pump.

 

Yeah the the filter is flowing the correct way.
This JEEP was posted on JeepTalk forum on Dec 2005 and no one replied until April 2007 which is when I noticed and jumped right on it :drool:

 

This is the only action the JEEP saw yesterday at JW Corbett before it stalled for the 4th time and I called it quits for the day.
