After changing the two filters I used the hand pump with both filters connected but the secondary not tightened so I could see the fuel leaking when the secondary filled. No sign of fuel at the secondary connection after about 5 mins so I removed the secondary filter to see if I managed to hand pump some fuel in it. None. So now I hand pumped for another 5 mins with the secondary off to see if any fuel was being pumped. Nothing. No drips from the secondary filter housing. I have the new black hand pump that I put on a couple years ago. Somehow the see-thru primary filter got filled but I'm not sure if it just filled from the fuel line by gravity or by my pumping.

I'm wondering if I need to pump longer to get the fuel moving? Should I be able to see fuel dripping from the secondary filter housing without the filter connected or does it have to be sealed with the filter? The fuel does not seem to be moving in the see-thru primary

Yes, you should have Fuel gushing out after 5 minutes of pumping.
Was the a routine Filter change or were you changing the Filters because there was a Problem.

However, the above assumes there is Fuel in the Tank, the Tank Screen is not plug and there is no Air leaks in your Fuel Lines.

You could get a longer Fuel Inlet Hose and run it to a seperate containter with Diesel Fuel and see if it will pump that with the Hand Primer and also try Cranking the Engine. If cranking the Engine does not work I would suspect there is a problem in the Fuel Supply/Lift Pump.

(All of the above assumes you are using Diesel Fuel and not a thick alternate Fuel.)

If it will pump Fuel from the separate container and you have about 3/4 Tank of Fuel try swapping the Fuel Return Hose with the Fuel Inlet hose. This will bypass the Fuel Tank Strainer. But, you will be drawin Fuel from a higher position in the Fuel Tank and that means if you continue to drive like that you will run out of fuel before your Fuel Gauge Shows empty.

I would think so too, but take the spin on filter off again, fill it up with fuel of some sort and try again.

If you have done any cranking of the Engine without Fuel in the Filter you most likely have Air in the Fuel Injection Steel Hard Lines. Loosen the Hard Line Nuts up at the Injectors to let the Air out and tighten them when Fuel come out of them.

toomany MBZ, Diesel911 Thanks.

I did what both you suggested and ended up replacing a 3 inch piece of fuel hose from the see-thru primary filter to the lift pump and now diesel is flowing.
I was replacing the fuel filters because the original problem is a loss of hill climbing power. I posted the thread link below and was following the suggestions (1. Checking banjo connection to intake manifold and associated line and 2. Fuel filters). I just took the car around the block and it ran ok but tomorrow I'll try a steep hill to see if fuel filters or the hose corrected that problem.

How does this idle sound?

Cool.

Glad it might be an easy fix.
I had a hard Fuel Inlet hose that appeared to be clamped tight. But, when the Engine compartment was hot it would cause a small Air leak at idle.

I found you could actually twist the hose around the Plastic Filter Nipple.

I replaced both of the Fuel Inlet Hoses and that cured the problem.
