Have a 2006 Duramax 6.6 pushing a 32' Gulfstream Endura RV with less then 20,000mi. I changed the Fuel Filter and did not prime it. I started the engine and it ran nicely for about 10 seconds, then quit. I then read the owners manual and learned the correct way to prime the filter. My problem is that now, it will not take a prime. I've depressed the 'plunger'' located ontop of the filter housing several hundred times with no fuel ever reaching the, now removed bleeder valve. There is a "half tank" of fuel. Any help would be Greatly appreciated!!!
Optional Information: Year: 2006 Make : Chevrolet Model: Gulfstream Engine: Duramax Already Tried: checked all o-rings for correct placement,manually filled filter, and tried a "prime" as per the owners manual.
Hello, I'm Cam. Please include all the details about your issue so I can accurately advise you. I cannot see your vehicle so please be detailed.
Did you open the bleeder on the top of the fuel filter then pump

yes i did
I suspect then there is a leak on the filter. Can you remove it and check?See if a seal has come off or something. Other than hat you will need to keep pumping.
I've done that!! Both O-rings are tight and have a good seal. Is there a possibility that the line has SO much air in it that it it won't allow a "draw" start?
Yes, that is exactly what I am thinking. So John, can you open the bleeder and pump till solid fuel comes out then close it and pump about 50 times, then has someone crank the engine while you keep pumping?
Cam, I thank you for hanging in there w/me!!! Thus far, I have removed the new filter & reinstalled the old one (It's in good shape & flows well) I have a good seal, both where the top o-ring meets the housing & the bottom o-ring attaches to the water seperator (all in good shape - clean/no cracks/etc.) I have completely removed the ''bleeder valve" and pumped at least a thousand times (no exaggeration) NOTHING!!! I've checked the fuse, relay switch and, when I turn the key on, can hear the fuel pump engage!! While i'm "up on it", pumping away like crazy, I figure that I should eventually feel some sort of resistance, some pressure starting to build....something!!! But........NOTHING!! HELP!!!
So the filter primer feels extremely loose? If so, then I suspect your filter head has failed. There is a workaround if you have an air compressor. Put approximately 5 psi air pressure into the fuel tank and bleed the system that way.
Yea? Was wonderin about that! Should I have the bleeder valve open during this process and, should I get someone to depress the "plunger' while I shoot the air to it?
When I removed the fuel cap, I was amazed at how much pressure it was under!! I pushed air thru, as per your suggestion, and still nothing!! Any more suggestions?
That is strange. Does this have a lift pump on the frame rail?
I don't know what a "lift rail" is, but i'll check w/a friend of mine and let you know?
I meant "lift pump", on the rail.
Sure, let me know .
No lift pump on the rail, that we can see. Today I added 12 gallons of fuel. Manually filled filter and then topped it off by placing a small hose into the bleeder valve and sending small amounts of fuel thru, until filled, then pumped hundreds of times!!! Still, not even the slightest resistance on the "primer pump"!!! WTH???? AAAAARRRGGGHHHH!!!!
Take the filter off and fill it. Try after that.
