Re: Engine stalls a few minutes after start up. Reply #26 – March 16, 2014, 04:51:04 pm Just a bump. I want to order the Racor filter just looking for a little input on my last post.Thanks, Phil Quote Selected

Seems like that's not what's happening here but thought id throw it out there..Yes, the DDEC will shut it down but you will also see a "shut down" light on the dash; with a fuel issue you won't.

Reply #31 – March 17, 2014, 10:23:32 am Peter, I Would steer clear of this after market supplier, they are not providing Cummins Fleetguard filters, without a clearly marked non fuzzy pix, I would rather go for the NAPA / Wix, at least they have a fairly good reputation. PREFER Fleetguard by far.Besides, their pricing is for folks who have no clue.FWIW or MODave M Quote Selected

Re: Engine stalls a few minutes after start up. Reply #34 – March 18, 2014, 01:13:28 pm Thanks for all the input. I have ordered the Racor 790R30 to replace the existing setup. I am hopeful this will get me through for a while till I can schedule fuel line replacement . Although I don't see any sign of deterioration on the lines at this time from the limited areas I can see. Quote Selected
Re: Engine stalls a few minutes after start up. Reply #35 – March 18, 2014, 02:34:49 pm Rather than scheduling a fuel line replacement that you may or may not need, try low AIR pressure on the fuel lines and then using a spray bottle with soap bubble solution, check for bubbles. Will be easy to see them. Most likely at the inlet/outlet at the fuel tank. It will only take a couple of PSI as very much could damage the tank. Fuel lines will need to be purged of fuel. This will also check on the lines to the generator.Pierce Quote Selected
Re: Engine stalls a few minutes after start up. Reply #36 – March 18, 2014, 05:11:46 pm Pierce,Great suggestion for troubleshooting air in the fuel lines. Where and how would you apply the air pressure?Thanks,Jerry aka Murph Quote Selected
Re: Engine stalls a few minutes after start up. Reply #37 – March 18, 2014, 08:04:31 pm Jerry,The hoses in our rigs are probably good for the duration but you never know who the supplier was as they are not all equal and a batch without the correct specs won't be as resistive to diesel and any additives. As a kid, I worked for a big car dealer with a lot of different car brands. American Motors had such bad rubber hoses that even the vacuum hoses were lucky to make it a year. That and cracked exhaust manifolds. No wonder they went out of business. So, you would need to disconnect the return line at the engine. With the tank cap off, you could take a air gun at low pressure and blow out the fuel in the line. The return line most likely terminates high in the tank. The feed line from the tank could be done the same way starting at the back and blowing the fuel back into the tank. A small air compressor with a Harbor Freight air regulator set to 2-4 psi would supply the air. With the filler cap back on the tank, air could be supplied to the feed line at the back and once the pressure was at the above psi, you could spray the bubble solution on the lines close to the fittings and do the feed and return lines at the same time. The generator could be done the same way. Just a little planning would be necessary with a couple of adapters to connect to the lines. Our fuel tanks will build pressure while driving so this would work well. Others may have a vent on the tank that would have to be covered or shut off. Could be hard to get to. Sort of like finding a leak in the HWH lines or air bags but with much less pressure. Bubble solution is great stuff and the bubbles last a long time so leaks are easy to spot.Plenty of other spots for air to find it's way into the system. Filter "O" rings are famous for introducing air on certain models/brands. Ford 6.9-7.3 diesels had a filter assembly mounted on the engine that caused a lot of trouble. Besides the filter, it had a fuel heater and a couple of sensors mounted as well as badly designed drain so lots of opportunities for air leaks and leak they did. When I installed a 7.3 in a Southwind, I round canned the whole assembly and just mounted a remote spin on filter up in the nose.Pierce Quote Selected
Re: Engine stalls a few minutes after start up. Reply #38 – March 20, 2014, 12:09:01 pm Pierce,Thanks for the procedure. Something to try that may show a leak at a connection before replacing the whole hose. I don't have any problems now, but I can file this in my memory bank for future reference. Will it be necessary to reverse the procedure before reconnecting the fuel lines to bleed the air out of the them? Jerry aka Murph Quote Selected

Will it be necessary to reverse the procedure before reconnecting the fuel lines to bleed the air out of the them? Jerry aka MurphJerry,Once the lines are connected again, you can loosen the big spin-on (mounted on the engine, driver's side) fuel filter a turn or so, put a gallon plastic bag around it to catch any spill and then use the frame mounted hand fuel pump to bring fuel from the tank to the filter. When bubbles stop coming out, tighten it, pump for another minute or so and then you are ready to start. I mounted a 0-15 psi gauge on top of the primary filter so I can tell the pressure is building when I pump. Easy installation with the gauge just replacing a threaded plug. I then mounted another higher pressure gauge on the outlet of the secondary filter mounted on the engine. It has to be for 60 psi or more as the Detroit fuel pump gives the system about 30 psi at idle and 55 psi at higher RPM. It is a little more work as an fitting has to be added. See attached photo with the Detroit idling. The gauge in the attached photo will tell if there is any restriction like clogged fuel filters.If the hand pump does not work, pull it off and replace the "O" rings. About $0.10 at NAPA. If O rings are broken and the nut not sealing the shaft, air can also get in the system so good to check. With the low pressure gauge, you can tell the condition immediately. Pumps easily at first, then a little harder and then quite a bit harder with the pressure about 9-12 psi.Pierce Quote Selected
