    FS or parts, 7.3l idi

    I have the pump and bracket from the truck only. I left the Van one on as it was serpentine rather than vBelt.

    What's a 6.9 or 7.3 N.A. core worth?

    I have a 7.3 from my 90' truck with 190K on it on a shelf, ran fine but had a head gasket leak, oil into coolant. Just got a recent rebuilt from a yard and changed it out. Love to get rid of it, but not sure if I should keep the pump or heads or part it out or scrap it? Any feedback?

    New engine but low power. 7.3 IDI

    Put my new fuel filter on, on Sunday. Wow, even the pressure at idle went up from 4 to 5 PSI, Now the pressure stays above 4.5 PSI at all times. The old filter (that came with the engine) was packed with junk, It spilled out as soon as I took it off and filled half the cup I poured the oil into.

    Low fuel pressure, At the time I tested it, it was already pretty warm, I ASSUME that last week when it was 40 deg cooler, the pressure would have been much lower. As I drove it (and the fuel circulated and warmed) the pressure drop under load almost went away entirely. I also am assuming that...

    I took the truck out today with the fuel pressure gauge on it. At idle I have 4psi. The filter definitely needs to be changed. When I first when up a hill. The pressure dropped to 0.5 psi. But I didn't lose power. This was our first hot day here, 80 degrees. As the fuel in the tank warmed up...

    New engine but low power. 7.3 IDI

    If I can get the Kent Moore J33300 and the wires are long enough, I will try driving with it connected and check that my advance works. Is there anywhere I can find a graph of the advance curve it should have? Is there a difference between an automatic and manual transmission curve? There seems...

    It sounds like there is hope. I verified there is a pressure sending unit on the filter output and that the dash light works. It's a small light, It might have been on and I might not have seen it, The way it's wired it will only come on when you have low pressure/vacuum. I found a fram PS6554A...

    I have no idea, from a couple hours research, it seems like it will do what I need and I can use it on the CAT (TH63 telehandler) as well with a timing light and maybe a different pickup. icanfixall said that's what he rents out and no one has chimed in that it won't work. The J33300A seems to...

    That's just the prices I was seeing on Ebay for used Timing light adapters ($300) and used digital timing lights ($100) I am waiting to hear back from someone local on a J33300A for $90. If it works, I will snag it for that price.

    New engine but low power. 7.3 IDI

    I replaced the short hose to the frame with a loop, since I couldn't get it on without kinking. Could be the lift pump, it got a bit bent when the engine was pulled at the wrecking yard. I am already looking at the kent moore, I sent him a message to see if he has the 1/4" clamp, I can't see...

    The setup seems to be around $400 for the adapter and digital timing light.

    Yes I will definitely not get wild and crazy with the timing and return it to where it is currently if there is any degradation in performance or mileage. Since it starts and runs so well and idles so smoothly I am leaning towards thinking it's a lack of fuel at the moment. It's a very dramatic...

    New engine but low power. 7.3 IDI

    The engine came out of a E350 van 1994. Just went and checked the throttle, it moves all the way. When I give it more than half throttle, the exhaust takes on a funny tone, kind of a high pitched resonance. Next time I take it out I will hang a fuel pressure guage on it just after the filter I...

    New engine but low power. 7.3 IDI

    Just swapped out the engine in my 1990 SuperDuty for a rebuilt one from a 1994 van with about 20K on it. The old one had 190K miles and a head gasket leak but ran fine. The new one starts easily, idles smoothly, No smoke of any color, runs great but has about half the power of the old one. It...
