Well, guess I missed/forgot about that one [thumbzup] All the hoses are fairly new. But maybe it got kinked somehow or something, i don't know. The hose on the IP looks fine, I may replace all of them though. I've never had a fuel return line have a blockage, even more so when it is mostly all...

Ok, after a lot of headaches and further... "diagnoses"... I have come to the conclusion that I must be a dumb🫏 anyway, I have went through 3 new lift pumps 1st: installed the new Delphi... didn't work, figured pump was bad out of box. 😠 2nd: Installed, worked, truck ran, but a 90 degree...

The old one and the Delphi both have straight arms, as shown in pics. The Carter has a "indented" or bent arm

Can you tell me which arm is right WWRD99 ? * I'm attaching the pump thats been on the truck since 2017 ** Then the one I installed on the truck in recent weeks that didn't work. ***Then the Carter one that I ordered from the link you dropped - it has the indented arm.

well, i got the part # earlier in this post somewhere I think, because I knew there was 2 that were similar. And the pump I installed looked just like the pump I took out of the truck.

Ordered 3 of them just to keep a couple on hand, and because the shipping was the same for 1 or multiple.

Is Carter a good brand? You think the diaphragm and such are still good on NOS? I bought a NOS fuel return hose kit, and they didn't last a year. Had to replace with new Viton hose. The previous pump that was on the truck, which I installed around 2010, was a AC Delco. This one that was bad out...

Well, apparently this lift pump is bad. Before I began digging further into the fuel system, I thought I would connect a hose to the hard line going to the lift pump, and drop the other end in a diesel can. Cranked truck with pink wire off fuel injection pump, fuel only lifted a couple feet from...

I pulled from the top right line on the fuel filter, which is the line that goes to the lift pump. Is that what you're talking about? I also tried to pull from the vent port i guess you'd call it, where normally you can open to release air until fuel begins flowing. Which that port is on the...

I forgot to say that I did try to pull a vacuum off the drain hose, with the drain/vent cap open of course. Didn't get anything there either. Tomorrow I'll unscrew the plug on top and try to pull from there. And yeah, I know it takes some cranking, I've done it a number of times before through...

Hey all, been a few months. been dealing with health issues and etc. anyway, worked on this fuel system again today. I got the pump on last week after 3 previous days wasted on it. But screwed up the first new hardline I bought. So bought another piece of 3/8" brake line and tried again. Had...

Thanks so much for the tips, now that you brought that up I think that I may have done that originally with the line. Also the rod didn't fall out this time, I even felt in there a bit and didn't feel anything. But I thought it was just my memory crossing over to something else I had worked on...

Thanks for the tips and for the nut size. I should have known it would have been in there too. I think I'm going to have to replace the steel line, I may have damaged/cracked it the other day. Just going to go ahead and replace it now, as I don't want to have to do this again.

Hi TechnoWeenie, appreciate the post. I just recently realized that my batteries could be a bit weak. I do have an "emergency" button override already installed in my GP system, but I only intended to use it if the card failed or etc. I also installed a new GP card in the year or so after I...

I had read something about two pump numbers, but didn't know the difference in the pump. I just ordered the Delphi from Amazon. As to rock auto... I had ordered from them for I don't know how many years. But back several months ago, I ordered a full set of rotors, calibers, pads, etc for my...

you don't happen to still know the part number to that new pump do you? I believe my pump may be quitting on me after 13 years or so. I have considered an electric pump. But a mechanical pump will work without electricity if the alternator or something goes bad, so there are pros/cons... but I...

When it warms up, I'll use a clear hose on the IP like you said. And I may order a lift pump too, can always keep it on hand if not needed now. I last replaced it around 13 or 14 years ago. Its a pickle to get the bolts started when reinstalling if i remember right. It was an ACDelco 43254 from...

Well, i had used some nos. but some of it just didn't last, especially anything with rubber. I'll have to look some more, see if there is air getting in somewhere or if its something else. I just thought... if there is air there might also be a leak... i might try my black light tomorrow and...

I never had any issue before this, except last winter which was fixed when I replaced my Glow plugs at that time. Thats why I originally couldn't understand why they were bad already. But found out today that they weren't bad. So i'm not sure whats going on now. Unless I'm missing something, it...

Ok.... I'm even more perplexed now. I just tested all the old plugs, and ALL of them Lit up. I tested them like CucvRUS told me to back several years ago. Take plug, use jumper cables to a battery, place ground clamp around plug, dip tip of plug in oil, touch spade connector on plugs terminal to...
