    Hi, my 1994 P-pumped 12 valve has a bad fuel leak. Whenever I shut it off I lose fuel prime. When I pop the hood I see diesel all around my p-pump. I saw fuel all around by my AFC housing.

    So yesterday I was diagnosing a random oil leak I found near the front of the truck, now it makes sense where it was coming from...I started her up and she was idling a little wonky but nothing crazy. I had to run in the house to grab a part and I heard her start to run away. I ran out and it by...

    Hey guys, so I bought the truck with no AC and I have had for about a year and decided I need to dive into it. For starters I do not believe it’s been converted to r134 as I don’t see new fittings. The AC doesn’t blow at all through any speed so I assumed I should get it to blow first then worry...

    I recently bought a 1990 d250 12v with a 5speed. I bought it drove it back 5hr home with no problems. I got it home and drove it to work for a week while I waited for some parts to come in. The week the parts came in I didn’t drive it for that whole week or start it. But prior to that start up...

    I've searched the internet deep and wide and can't find anyone else with a similar situation. Maybe someone here can help. So I thought the KDP got my ass, but come to find out, it was the bold next to it?? KDP is still where she belongs. I'm confused on how this could've happened.
  10. 89-93 Non-Powertrain
    So I bought my truck a few days ago and the heater wasn't working. Before buying parts I looked at the fuseable links and right at the start of the duckfoot the wire for the ac, heat and ignition switch is broke and corroded. I am just wondering what the easiest repair would be without removing...

    Hey y'all, I haven't posted in an aeon, all stuff I could figure out. Here's a good one tho. Piles of white smoke (unburnt fuel) out the exhaust, dead number 1 cylinder on a 95 dodge ram, CTD,12v p-pump manual that fires up instantly and runs great. On 5 cylinders. Cranking sound is even on...

    Hi I’m wondering if I can get 500-600hp from a stock 12v Cummins, this will be a daily driver so I wanna also get good gas mileage out of it too, and I would like to only spend about $2,000-$3,000 if possible on the engine build, and I’m wondering what parts I would need to achieve this? Thanks
