Hand Pump problems??
So the other day I replaced my filters and went to pump the system...I noticed fuel coming out of the pump as I pumped...it appeared to be coming over the top?? It still did its job, but I am assuming this is an issue. I am in the first stages of trying to work out a fuel issue. The car is hard to start, and I must hold down the accelerator for a good while before the idle smooths out. While I am waiting for the idle to smooth out, I am seeing lots of diesel smoke, as if too much fuel is in the chambers. Once she is warn though, all is well, good idle, no smoke. I want to start with the simple things first...if there are such things.

The best way that I have found to remove the old one is with a plumbers "faucet wrench", gets right around it and you can get plenty of torque.

If the pump has a white handle, that's the old style and they are suppose to spill fuel as you pump. With the price of diesel, you are better off replacing it with the new style ($10 with a black handle) that won't leak. I used a short pipe wrench (about 6" long) to get the old one off. Worked well, chews it up but who cares?

Guess I need to hit the pluming supply store...mine is the older white colored hand pump. The car is an early 81 300TDT. I saw a newer version in a salvage yard, so this weekend I will go grab that, and a few other things. What would cause too much fuel to be in the system at startup??

i dont know about too much fuel, but a leaking primer pump could be the cause of too much AIR, and therefor causing starting issues.

What you do is to remove the threaded nipple to the immediate right (toward the rear of the vehicle) of the pump. Then, you've got access to the pump with standard open end wrenches.

I've replaced five primer pumps, all with vise grips, they are going to be replaced, so no need to worry about destroying the old one.
But you may be able to use a stubby 17mm, that's what I use to install the new one.
