Need help with a Deutz diesel

[acesneights1]

Does anyone have any experience with deutz diesels ? I have a 3 cyl air cooler one in my New Holland and it's losing power under load. I found the fuel supply line leaking at the LiftPump but that did not solve the problem so I would like to test the output pressure on the LP (it is mech) but I don't know the spec. It looks to be a Bosch 3 cyl IDI injection pump so I would think somewhere around 4-8 psi ?? Also if the Lift Pump is bad any reason I couldn't use an electric one ? I can only imagine what the mech one from Deutz costs.
I gotta get this thing fixed asap.

You changed the fuel filter right?

Not yet, I had to order it. It will be in tomorrow but i see wetness around the lift pump so I suspect failure.

If the lift pump has a round stamped steel cover held down with a 1/4 inch screw, remove it. Some have a flat brass screen underneath which are usually neglected. Just a thought.

I shot an email to Long Island Deutz. They are the closest dealer. I will check for the screen as well. I may need to get a metric adapter for my hand priming pump as the fuel filter for whatever dumb reason is mounted upside down so there is no way to pre fill it.

It would not surprise me if the factory LP was 500$. Anything for this engine is insane. One cyl head was 1200$. Good strong engine but when it breaks, it breaks expensive.

Auto machine in Orlando has and can get parts for Duetz A lot cheeper than anywhere I have found. Is it possable your pump is leaking because the filter is plugged?

It does have that cover. I am going to remove it as well as the spin on. Long Island Deutz said 10 psi but I think that is excessive. He sounded unsure. He said the Lift pump should have a primer handle but I could not find one.

YOU ARE THE MAN !!!
It was actually plastic but probably a replacement from original but it was clogged solid. BTW for informational purposes the Lift Pump puts out up to 30 psi and from what I was told the Bosch inline IP used on this motor has no internal transfer pump so it relies solely on the fuel pressure from the external one.

The reason manufactures mount filters upside down is so people dont pre-fill and contaminate the system. Install dry and pump it full, I will agree sometimes it sucks. But your fuel system will live longer.


That little screen has caused a fair amount of grief for a number of people. Glad you found it.

Since the tank is higher than the ff I put a small amount of air Pressure in the tank and loosened the banjo nut on the ip and forced the fuel into the filter. It worked perfectly.

That works too. So, does it run now?

Garp is the man!!! I now know why the fuel filter on my A3 is upside down.
From German motors to Cat's Garp knows it. !!!

So far so good.
