Parts are very expensive, head and gasket almost $2600 at Freighliner dealer of course the pump is more expensive, my first time trying to fix one of this pump, I appreciate this excellent video 😊 fingers crossed and hope it works Thank
Just for any viewers cummins is all metric spanners btw on all of there bolts internal and external The imperial stuff will get you out of trouble though just in case anyone only has metric spanners and sockets
Good morning On the first high pressure line that you remove, on mine it's leaking,there's a gasket or o ring I need to replaced or do I need to replace the whole line??. Thank you
So you mean to tell me that you / I don’t have to remove the whole assembly? In other words your saying that when the fuel pump goes out all you would replace is the head unit? And leave the rest of the assembly on? Only asking because I have one of my vehicles with a ISL 9 2350 CUM and I have no fuel pressure..
Great video sir.! I have Cummins isx 400st my truck is loosing power at about 1600-1700 rpms going down the road no trailer. Do u think it might be caused by fuel pump failure.? Do u know how I can troubleshoot this issue? Thank you 🙏🏽
First thing I'd do is put new fuel filters on if you haven't yet, next would be check air filters. After that it would be good to get it it scanned and see if any codes come up.
@@zedperformance yes sir. I’ve done all those things already. It just left the shop yesterday and the Mechanic deleted all codes except the amber check engine light but he told me it will not go out do to egr being deleted.? Also code j1939 datalink is on my dash idk if that would be the issue.? Thank u
@@Jreddygo Have you had the ecm tuned for the egr delete? For low on power I'd wanna scan the engine and make sure rail pressure is where it should be. Also you'll wanna check boost and make sure it's where it should be also. I don't know the specs off hand, but you can log onto cummins quick serve and create an account. That will give you access to every spec/procedure for your engine.
@@zedperformance yes sir. That is what he was doing because I replaced my ecm with another reman one because originally it was giving me more issues. But now pretty much that’s my only issue is it’s loosing power. Once he connects the software can he check if I’m getting proper fuel pressures.?
Could you. Hook me up with some advice i got 870cummins. 14.9liter. 08volvo. Ive lost my jake cruise control and fuel response im get a1939code. Love your videos.
