My friend is having a problem trying to prime an 1850 Perkins diesel after a complete overhaul. He says he pumps it 8-9 times and it goes soft(whatever that means). He has bled the filters and I believe the pump properly, cracked open the injector nuts but only a slight dribble of fuel comes out and not a squirt. All ideas would be appreciated.

The tractor is up and running now. Thanks to all that replied. I passed every one of the replies on to my friend and he appreciated them all.
Thanks again.....

I have two perkins a 4 and a 6 and they both prime the same, you have to get all the air out of the pump then crack all the injectors until I have fuel at all of them. Then I close all but one, the motor will usually start and then close the last injector. I also set the throtle about half open. When they are dry it takes some pumping to fill the injector pump. Just remember to watch your cranking time and let the starter cool down.

That's about the easiest diesel to prime that I've ever seen. Just open the bleed screw at the top of the Injector pump,pump the hand pump until fuel flows without bubbles.That's it.

I had trouble with my 2050 after changing fuel filters. A guy I used to work with told me to pump the priming pump while turning the engine over. I thought "yeah right", but got her started that way . I know it's a completely different pump and set up than the CAV, but it might be worth a try.

Well, he is still having problems. He has primed the injector pump but can't get fuel any further. He had a hard time just getting fuel to there. I wonder if the injector pump could be dried out from sitting or full of residue. Any other ideas? Everyone has been helpful so far.

Had to blow air in the tank on my M5 Moline to get it started after running out of fuel. I put a squeeze ball like on a boat in the line befor the filter, no problem now. I think they use them on new Bobcat skidsteers now. Steve

Due to my fuel level sensor not working and my wife driving the tractor my 1850 runs out of fuel at least once a year (usually in the cold and in the field). I have found that the system can be hard to refill. I now start at the primary fuel filter and loosen it so it is hanging, wait until you have spilled a couple of pints of diesel and tighten it up as the fuel is pouring through. I then loosen the secondary filter before the CAV pump and now I start using the primer lever on the fuel pump. It could be as simple as replacing the fuel pump diaphram but assuming it is working pump the lever until you have no more bubbles coming. Tighten the secondary filter and then crack the lines on top of the fuel pump. Prime until there is no air bubbles. I then move to the top of each injector and prime again. This usually will have the tractor going again in about 15 minutes. If you can plug in the block heater to warm up the engine all the better.

I've primed mine a couple of times this spring as I worked on a fuel tank leak. Best way is to use the air compressor and pressurize the fuel tank, get the fuel filters full, then crack the lower bleed screw on the injection pump first, then the upper one last. I never worry about the injection lines as mine starts right up after spinning 3-4 times.

We used air on the fuel tank on some of our vehicles that had Cummins diesel engines. It worked every time to bleed the air. Here's a picture of one of the vehicles used for drawbar and cooling tests. It has the Ford 500 hp gas engines when this picture was taken and they were replaced with Cummins in 1965. Hal

There are 2 bl;eed screws on the injection pump. Fuel will not squirt out of the high pressure lines. How many high pressure lines did he loosen? Did he loosen them on the injector end?
