    7.3 IDI Tachometer Woes

    I recently acquired a 1993 F250 4x4 with the 7.3 IDI for $2300. Came with a dash saying 150,000 miles, but who knows if that's accurate. It seems this truck started life off as a V8 gasser and one of the previous owners must've swapped in a 7.3 IDI and E40D auto. All things considered, this...

    6.9 idi tachometer reading 2x actual RPM

    I have a 1994 f350. It was originally a 7.3 powerstroke and a previous owner for some reason put in a 1983 6.9 idi. I installed a 1993 idi wiring harness, Ecm, and a newer injection pump drive gear housing with a tach sensor. When I fired the truck up it was reading 1500 at idle. The truck has...

    Hard start, when warm outside.

    I recently have finally gotten my truck registered, and have been driving it to school, and filled my front tank as it was getting low, because of this I switched to my rear diesel tank, and had a small amount of white smoke coming out of the tail pipe. I figured it might have been that I just...

    Sound levels

    Howdy, I'm new to the whole idi thing. But long story short I'm putting a 7.3 idi in a s10 with 4 inch pipe and glass pack style mufflers. But I am wondering how loud it is db wise or in comparison to something. It will have the zf5, 4.10 gears, and 35'-38' tires Thanks in advance❤

    Electrical/Battery Mystery???

    I am truly baffled at this point. I recently became a victim to bad batteries. Both batteries were within 3 years of age but my truck is not driven daily so I expected a little less than full life on the batteries even though a good battery should be okay with no use for months if stored...

    1993 F250 7.3 IDI fuel return line to tank

    Does anyone know where I can find a replacement for the return line that goes from fuel injectors to the tank? It runs along the frame. I have a hole and significant leak in mine right as the line meets the frame, further down from the 3/8 hose that is connected to housing on left side of engine...

    Have a 1993 7.3 idi (non turbo). I bought the pick up recently, ran pretty well when I first got it, started having some problems with it, some I have worked out but I think I’m still having a serious fuel delivery problem. These two forums pretty accurately describe what’s going on with it...

    Secondary oil circuit for turbos?

    I'm working on getting twin turbos on my 89 7.3 idi. And I'm thinking instead of using the engine oil, I could make a secondary oil system just for the turbos. For that I would just need a oil pump capable of constant pumping, a oil reservoir, some oil lines, and a switch. The advantage would be...

    93 7.3 idi locked up driving down the road

    Hello, I have a 1993 7.3 idi that locked up going down the road on my son and I. All was fine, then a metallic crunch and we coasted to the side of the road to wait on a wrecker for 4.5 hours. Anyone who hasn’t spent 4.5 hours on the side of the road with a 6 yo son just hasn’t truly lived. Any...

I’ll allow multiple choices if you want to put down historic engines you’ve had. Poll is: how many miles as your engine lasted before it either died and got scrapped...

    Air bubbles in clear fuel return line

    i have air bubbles in my fuel return line, the clear one that goes back into the IP. Usually you don’t see them until you tap the start of the line down near the injector at the front driver side. It has screw down clamps on the hose, tightened those to see if it would help and the bubbles...

    Engine acts like it hits boost, without a turbo

    I have a 89 F350 7.3 idi with an unknown amount of miles, my guess is it rolled over twice so 214k miles. IP is definitely a replacement because it's not painted. Previous owners were crackheads so no info from them. So I accelerate in third gear (ZF5), steady pressure on the pedal, and it...

    7.3 idi max rpm governor screw

    Because rpm in a Diesel is controlled by fuel wouldn't removing the throttle limiting screw make the pump put out more fuel or will totally removing the screw cause something in the pump to mess up.
