Need help with case 1594

Riversedgefarms · Feb 15, 2025

Good morning i really need some help diagnosing a intermittent problem with my case 1594
When under load there are times it will drastically loose power and sound as if it's running out of fuel. But if you idle down and stop the machine it will regain rpm and idle fine. Sometimes after one of these episodes if you rev the engine to anything over 1300 rpm it will do the same thing. I'm really hoping I'm only dealing with a bad lift pump and not a failing injector pump. If anyone has experienced this any insight would be much appreciated.

Does this have a fuel filter pre lift pump? Fought similar problem on a Maxxum there was a tiny filter in pump inlet "plugged" it was about the size of the end of my little finger, had to cut band off pump to find it. thought I had some pictures must be in an old post. HTH Tom

Did you try changing the fuel filters? We only know what you tell us, we can’t assume to know what steps you have already taken.

I have had the line from the saddle tank get filled up with congealed fuel deposits. Start at the tank or lift pump and work your way towards the problem to were you don't have fuel.
