First- my heartfelt thanks for all the postings on duece operation and maintenance. Because of those postings I was able to troubleshoot my problem today. I took my M35A2C out for the first time this spring. It started up on the first crank and I let it warm up for 20 minutes before my trek. I did the pre-check walk around for leaks and everything looked good. I drove about 5 miles and it died. Doing some G2- I noticed that I had a significant amount of fuel on the driver side undercarriage. It was coming from the fuel supply pump attached below the IP. Taking a closer look, you could see the cracks around the fuel inlet fitting on the casting. Normally this would not be a problem- just messy- but it now looks like my in-tank fuel pump either is or was not functional. My gut feel is that crack just happened and the fuel tank pump was probably never working since I purchased the Deuce 18 months ago. No, it was not the fuse because where the fuse should have been was a metal rod acting as a conductor- so much for the need for a fuse.
I had over a dozen folks stop and ask if I needed assistance. One young gentleman even towed me 100 feet to get out of the intersection were it died. He was on R&R from the Desert and said that he could not wait until he got back to his buddies and told them that he had towed a Deuce with his new Chevy pickup. His next question was-- you're not a Ford guy are you??? . I lied and told him no.
Bottom line- some neighbors came to my rescue with a spare 12 volt fuel pump that we plumbed into the line and a spare 12V jump/charger rig -we got it going and home. Bubble gum rig but it worked for the 5 miles that I needed.
Whew- now my questions- looking at TM 9-2910-226-34 for the IP -and the location of the fuel supply pump assembly- can this be removed/replaced as is or does one have to raise the motor off the mounts to get at it? I'm thinking that it is going to be a major effort to replace whereas the in tank fuel pump will be easy. I might just want to try some of the epoxy sealing kits on the exterior of the pump casting to see if I can get it to stop dripping. With a working in-tank pump- I should not have to worry about the fuel supply pump sucking air- my quess as to why it died today - Any experience or success with a particular brand of epoxy?
Thanks in advance----> Les

. Just kidding! I don't think epoxy will work for you. Diesel has a bad habbit of getting through everything, so the bottom of the pump will most likely need to be removed. Don't how to do it, I have never had a pump off or apart. Maybe cranetruck, rdixiemiler or Recovery4x4 will know that. As for the sucking air, if the bottom of the pump is cracked, yes, it will pull air into the system. If the in tank pump were working, you'd most likely have a drip/stream of fuel on the ground with the engine off and when the engine was running it would suck the air from the cracks. That part of the pump builds the in tank 10 PSI or so into 65-70 PSI. Take pictures. Sometimes it's easier to give advice if a person can see the issue.
you must read the pubs before revoving. It is easy just follow the steps.
