Thanks Mr. Firefly. There is nothing in front of the pump keeping it from sliding out. There was the oil filter but I removed that. It looks and feels as the internal lever is keeping the pump from coming out. Hence my question about the studs. I have the feeling that it needs to come out at an angle to allow for the internal lever to go through the hole. But the studs prevent that. I am a bit puzzled to read that you took yours out without removing the studs.

Greetings,
Mr. F. I wish I could be more explicit but I DID remove and replace a fuel pump without taking out studs....Oh, dear, to the best of my memory. Somebody help Mr. F out here. I'm not sure what day of the week it is...

Apologies but could you be a little more explicit? Should I push the start button? If that's the case, should I screw back the nuts while I do this? Thanks.

Can you apply pressure on the pump (pull it away from the engine) while someone else bumps the engine starter a few times? It seems the cam is catching the lever just so and the studs wont let you angle it off the cam.

If nobody around then just a quick bump then check if the cam has moved enough to let the pump go.

If the diaphragm inside the pump is torn from old age it can cause fuel to leak into the crankcase so check the oil level for diesel fuel in the oil, no biggie just change the oil when the new fuel pump is on.

This should not be a difficult job. You will get it, no worries.

I would either roll it over manually or put the nuts back on if you are going to bump the starter.
I would not bump the starter with the pump hanging loosely on the studs. If it kicks the lever the wrong way it may bend the studs.

True and good point, Murphy is always around and it could even damage the cam.

So yes, remount the pump and be safe no need to jurry-rig it and get it all cobbled up.

Good idea! The manual control is important.

Ok, I will try that. I had the feeling that it wouldn't be a good idea to crank the engine with the pump being loose. That confirms my suspicion! I'd rather be extra safe than risk creating some internal dammges that would be hard to fix.

Just bump the engine over a bit and that should push the pump out. Leave the nuts off. Don't let the engine start. :-)

How could it "kick" the lever the wrong way? its either pushing on it or it's not.

I've done this a few times with no ill effects. And you don't crank the engine over, you bump it over just a bit.

But do it however makes you feel comfortable.

I can't see in there so I don't know if it's possible for the lever to get in the wrong place somehow. After all it was jiggled and moved around a lot in an attempt to remove it. Murphy may have visited.

Success! I was able to get it out and install the new one in 15 minutes. Turns out the small lever was indeed stuck inside and all that was needed was to turn the engine a bit like some of you mentionned. I simply hooked a pipe wrench on the flywheel nut and slowly turned the engine until the pump was free (about half a rotation). As simple as that. Thanks a lot for the all the advice. Now I know how to change a fuel pump!
