Is there any reason why this this cap (Part # 1507 0014) would not be suitable for a 2004 LB7 D/A? I don't know of any fuel system change between 2003 and 2004 that would necessitate a different type of cap?
Just to be sure I took a visit to the parts dept at the local dealership. They could not find a part # for the 2004 D/A and they even called GM to verify. They did verify the part number for 2003.
I was told by my dealer that a locking cap did not exist for my D-max. While loking through this forum I found the part number for the cap mentioned. It works perfectly with no venting issues so far. The only thing is it has no diesel warnings on it so don't give the key to anyone who doesn't know the difference between gas and diesel! By the way the Delco cap is way cheaper.Edited by: BERK
