thanks for the info. Ill hafto make do with the truck for a week and half till next payday. i,am sure every one knows how that go:mad2: But i think iam goin with the walbro because ive had no luck with the ac/delco pump either.But iam preety sure its a lift pump problem.
I just put some of those 37 12.50 militarys on my dually. I had to search for months to find a set of 16.5 wheels for my truck. but man doese it look good. ill have to post new pics of my truck.
i replaced the ops a few months back. it is a factory replacement. so it still controlls the lift pump. il have to get a pressure gauge to check it.is there a thread for this lift pump relay mod?
I just put some 37 12.50s on the dually and now every once and a while ill get a miss around 2nd and 3rd. the truck starts to bogg down the it takes off like a bat outa hell! Any ideas, it doesnt do it all the time.
when i bought my truck of my boss two years ago he said it had a new fuel system. He had the dealer replace the ip. I think the dealer replaced the ip with a 6.2 mech pump. It has the letter J stamped on the tag.doese the 6.2 pump put out less fuel than the 6.5 td?
