    Scored a Zf5!!

    Scored a zf5 and a spare transfer case but sadly it came connected to a zf5 that I have to some how sell but that's a problem for future me. The e40d I believe is dying as I just couldn't get it to shift right with even a new TPS sensor so I let it sit for few weeks and when I went to get the...

    Glug glug after new IP, what's causing it?

    Motor hesitates after letting off throttle after installing a new IP pump and I can't figure out why. Also how does the timing sound? Glug glug - https://vm.tiktok.com/ZTdDwPJKk/ Sound after installing new IP - https://vm.tiktok.com/ZTdDwR3aG/

    Really wishing I had a zf5...TPS sensor.

    So I finally got to driving the truck (91 f250HD 4x4 e40d) with the new injector pump and the transmission shifted hard. I tried setting the TPS sensor and I just can't get it to shift like it did when I parked it...which was great! My voltage at full throttle with a warm engine was 1.2 volts...

    New IP installed, TPS question.

    Ok so I just installed my IP pump this week, and I haven't installed the TPS sensor yet but was wondering if I could install it without checking the voltage meter and drive it around or should it not be driven at all untill a voltage meter tests it's voltage?

    7.3 idi turned up?

    So I'm pretty sure my old pump was turned up but I just want to confirm....she rolls coal when floored (parked, not always when driving) and when accelerating up a steep hill empty going 70mph (gets to 70mph in a good time too) she lays down a trail of black smoke. She's also pretty peppy for...

    70cc R&D ip or stock CDD ip

    Looking at the two pumps the R&D idi is much cheaper but gives 70cc's and 400 extra rpms....my truck is completely stock outside of a duralift 40222 so I'm a bit concerned about the extra power and rpms on this one... however the price is more in my budget. The classic diesel design pump looks...

    600rpm runaway diesel

    So my truck wouldn't shut off after coming home from work. It's a 1991 f250 7.3 idi N/A with nearly no blow by. I deleted the mechanical lift that died with a duralift 40222 and installed a new cdr valve from eBay 6 months ago. First thing I did when this happened was turn duralift 40222 off...

    New pump, timing advanced?

    Installed a duralift 40222 after my old mechinical one died, truck seems to run better with it but she's less clattery and some have said she might be a little advanced? If so will that hurt anything? She idles smoothly, no smoke unless giving it a lot of throttle and then it's black which is...

    Fuel pump circuit breaker

    I know there are many posts about the duralift 40222 but looking at this relay kit, it says I could run the red wire directly from the battery to the circuit breaker, then run red wire to the relay and have the activation be from starter solenoid on the fender from fuel pump relay. I have looked...
