2 ways this can be done 1 lift the bed of the truck offso you can get to the top of the tank where the sender is located ( 8 bolts 4 on each side, three 9/32 screw aound filler neck and 1 or 2 plugs for tail lamps. Th other option is to drop the tank down by removing filler neck hose from tank and 2 straps held in with 15 mm bolts , It would also be helpful if the tank is as empty as possible...good luck

2005 Duramax stopped running.replaced fuel filter and sensor,no luck cam you help.


After replacing the fuel filter did you prime the system? There should be a small circular pump on top of the filter assembly to prime it. I own a 2003 Duramax and it usually takes about 5 pumps / turn over / 5 more pumps / turn over / and 5 more and you should get it started. It will take longer if you didn't fill the fuel filter with diesel before installing it as well. Let me know. Thanks.

The fuel gauge doesn't read at all, continually reads below empty and the low fuel light is always on. Duramax diesel runs perfect all the time


BAD INSTRUMENT CLUSTER ,GM HAS A PROBLEM WITH THIS. YOU CAN SEND IT OUT FOR REPAIR, THEIR ARE PLACES ON EBAY THAT WILL DO IT FOR YOU .OR THE FUEL SENDING UNIT IN THE TANK IS BAD ,IN WHICH CASE THE TANK WILL HAVE TO BE DROPPED.

2003 Duramax Diesel loosing prime and will not start until I lift the hood and pump the prime plunger on the fuel filter housing.


duramax diesel trucks do not have a lift pump. start with the simple things make sure your fuel filter is tight and check the shreader vlave on the fuel rail if that don't help check the filter housing for a leaks arround the heater element or a crack in the housing itself

We have a 2003 GMC Sierra duramax diesel truck We took it into the shop last week because it would not start. They told us that the fuel filter was sucking air and changed it. The truck then ran fine for...


i have a 2003 , 2500HD Duramax with 223000km . I was way up in the north country when this started to happen to my truck. I found an old mech. who had to come back into the bush to give a boost because i couldn't start my truck as well. He told me he has seen this before on the 03's. Long story short it was the injectors the dealer replaced all 8 under warrenty. GM sent me a letter later saying they will cover all diesel parts under warrenty for 320,000km and another 6yrs. its your injectors change your oil more often until you get it fixed. To check this park your truck for the day and try starting it if it will not start. Go under the hood and prime the fuel filter (pump until it gets hard) then turn the truck over a little and prime the filter again until hard then start the truck. if this works then get the injectors replaced by GM. This worked for my truck hope it helps. Rick

Priming fuel system on a 8.1L diesel engine 2001chev 1 ton dual


Well, one problem is, if its an 8.1, its not a diesel. The 8.1, or Vortec 8100, is a gas engine. The DuraMax is a 6.6 engine. There is usually not a priming system on a gas engine, because the fuel pumps will usually get it through the smaller filters used quick enough you dont need them. However, if it is a DuraMax engine, then right on top of the fitting where you mount your diesel filter, there is a primer pump and an air bleed valve. What you do is, open up that air bleed valve ( its a little black plastic octagon shaped thing on the top of the filter mount) then you pump the primer (the silver button looking thing) until you get diesel squiting out the air vent without too many air bubbles or gurgles.
