    Help narrowing down cause of the tapping noise..

    Yeah it would make more sense that way. But, is the knocking worse when the cold advance is on or no ? Jumper 12V to the cold advance terminal on the IP and if it doesn’t make a difference I wouldn’t expect it timing related. My truck recently started tapping/knocking a little when the cold...

    Help narrowing down cause of the tapping noise..

    Timing might be too advanced, I would check that first. Every time I had fuel knock symptoms they would also happen in park and I could just rev the engine and loosen injectors until it went away. One time I thought I had a fuel knock and was chasing it forever. It would only happen under load...

    2025 i.p. builder discussion

    I guess I had one of those too LOL. I did have CDD rebuild my pump with the 110 specs. No issues with them. But it does seem like they re-sell a lot of stuff at a higher price as their own. But it’s not bad if you don’t mind paying extra and just want a one stop shop for good IDI parts if you...

    Electrical issue

    I believe that’s the power for your glow plugs. Check that you don’t have any shorts on your glow plug relay.

    THSIM9’s 1991 F250 Project

    I just simply removed the waste gate and capped the 1/8” npt port. I got a piece of all thread from McMaster carr to connect to the existing piece that connected to the waste gate and tightened it down on the gate bracket. Grade B7 Medium-Strength Steel Threaded Rod, M6 x 1 mm Thread Size, 100...

    Blow by and Low Mileage Tare Down Questions

    Did you consider maybe it was fuel knock? I had a leaky injector and it was causing me to have a ton of blow by. Not as bad as you are describing though. Also I’ve heard that using PSD rings on these pistons can cause a ton of blow by. Hopefully you didn’t use those. Best of luck.

    Hydroboost Conversion

    So the tensioner took up the slack from deleting the vac pump?

    turbo replacement - clearance issues

    I had the same issue with that intake hat. I found that if you tighten the inside bolt on the y pipe to the passenger side exhaust manifold first, it swings the turbo out and away from the hat. If you tighten the outside bolt first it swings it in. I still needed clearance after that so I...

    Hydroboost Conversion

    Is that a serpentine belt that’s just a little shorter to bypass the vac pump? If so, where did you get it?

    Sounds like you got the legit stuff. I got mine off Amazon.

    Squealing Noise Until Operating Temp

    Sounds like a belt noise like you said. Why don’t you try taking the belt off completely and take it for a test drive and see if you still have the noise?

    Gunson 7708 Timing Adaptor

    Was your injector line stainless steel? My rpm readings would be all over the place once I got above 1200 rpm. Never could get a consistent read. I heard this from other people as well. I changed it back to the original line on #1 and didn’t have that issue.

    Gunson 7708 Timing Adaptor

    Just a fair warning, from my experience, the DTI unit does not work with the aftermarket stainless steel injector lines.

    Hydroboost Conversion

    71415 didn’t work for me, fittings weren’t right on either end. I used 71442

    Regulator Return Routing

    Do you still have a fuel tank selector valve? If you don’t, I think you might be able to tee into the return somewhere near the tank and it shouldn’t pressurize the return too much. I tried this out myself tee’ing into the return before the selector valve and it pressurized the return wayyy...

    Doomsday Dually Project

    Sure, I just welded a 12AN bung to the cover and used a low profile 90 degree 12AN fitting to clear the serpentine belt. Though a hose barb would work just as well and you could prob fit a bigger a hose on one. Routed the hose through a catch can and welded another 12 an bung onto my intake...

    Doomsday Dually Project

    After a nice break from working on this thing, I finally decided to convert to Hydroboost. Totally worth it if anyone’s on the fence about it. I know there’s about a million threads Hydroboost here, but I figured I’d share the parts I used here since that was a little tough for me to find on...

    Good replacement for Holley Black Pump?

    The wire connections were fine. Wiggling the wires going into the pump seemed to free the brushes up and start the pump. I’ll see if Holley can send me new brushes, these ones are toast. In the mean time I might buy a spare and set up a backup on a switch like @Kdo58. These pumps are too...

    Good replacement for Holley Black Pump?

    That’s actually a really good idea to have a backup. Maybe I’ll try to clean this one up and replace the brushes and use it as a backup.

    Good replacement for Holley Black Pump?

    Any ideas? Clean up the carbon and send it?

    Good replacement for Holley Black Pump?

    Yes I have a filter before and after the pump and I replaced the fuel tanks with plastic ones and all the fuel lines before I ran this pump. The problem seems to be electrical connections internally. May try and see if it’s covered under warranty. These things aren’t cheap, you’d expect them to...

    Good replacement for Holley Black Pump?

    What’s a good pump to replace a Holley Black lift pump? Mine just crapped out after only 1 year. If I wiggle the wires going into the pump I can get it to turn on a little. Not something I trust. I heard other places that Holley pumps are lacking quality. Anyone know of a quality pump that...

    Cold timing advance problem

    Besides injectors I wasn’t totally satisfied with the other products I purchased from him. I am pretty happy with the turbo I got from him but it didn’t come ceramic coated like advertised. Also, he seems to have a lot of attitude and talks a lot of trash on other vendors like CDD. I don’t get...

    Cold timing advance problem

    I tried to warn ya! I had the same exact thing happen. After I sent them back once and they still came back messed up, I was like that’s it I’m not wasting my time for a 3rd chance. Waste of $500
