    New here with a 6.9idi f250

    That's a straight Bullnose truck. Let us know if you decide to take the plunge and start running WMO. :Thumbs Up

    1987 6.9 IDI Losing Prime Overnight

    Make sure your mechanical fuel pump hasn't gone bad. I've had several go south on me and pump diesel into the crankcase. Just keep an eye on your oil level. :Thumbs Up I finally went to an electric fuel pump.

    6.9 IDI valve train questions + head gasket job

    Let us know what the measurements are once you get the heads clean.

    sticky equus gauge needle + gauge talk

    I don't think a digital gauge is any better than an analog gauge. It's just user preference. They both use a sender and the gauge responds to the signal from the sender. You can get a true mechanical gauge though. The vacuum gauge I have is a mechanical gauge with an analog display. It doesn't...

    sticky equus gauge needle + gauge talk

    I have an AutoMeter vacuum gauge, coolant temperature sensor and pyrometer in my truck. They work great. I recently bought a GlowShift fuel pressure gauge and just have it in the bag with my timing light and piezoelectric spark adapter. It works well too. I compared it to the older handheld...

    6.9 IDI valve train questions + head gasket job

    Did you measure the valve guide wear with a dial indicator and the valves in the head?

    Recycle oil

    Yeah, I might try to brew some BD. I think you can cut WVO with diesel too so it's less viscous.

    Recycle oil

    Good point. We'll see if I ever try to run WVO or brew some BD. I live in the suburbs of OKC so getting the WVO wouldn't be a problem for me if the restaurants I visit are willing to part with it.

    Recycle oil

    You can use Kolor Kut water finding paste when you get WMO or veggie oil used from an oil change business or restaurant. https://www.ebay.com/itm/178106256275

    Recycle oil

    If you have a friend that works at a quick lube that would be the easiest way to get WMO.

    So what did you do with your truck today?

    Fuel tank work on these trucks is a PITFA! I've never removed the bed, I can only imagine it might make the work easier. :dunno Definitely give it a day if it's fighting you.

    Fuel tank showerheads

    OHHH YEAHHH! That's an excellent idea. :cool:

    Fuel tank showerheads

    Sorry I gave you the wrong part numbers. :Q I don't know if it will help for your truck but I had originally ordered the following sending unit for my truck: FG114A I think I got it on RockAuto. It has a 4 prong plug (signal, ground, + and - for the pump). It's for the gas trucks with a fuel...

    Fuel tank showerheads

    That's crazy the connectors are wrong. Both of the FSUs I got from Amazon had the dual prong connector. I actually had to buy the wire end of the connector from LMC Truck for my side tank because I had tried to modify the circuit to a 4 prong connector on the FSU. That didn't work well. :idiot:

    Which replacement injection pump?

    I've read the same thing about Pensacola Diesel.

    Maxtow gauges

    Aren't there oil plugs on the back header of the oil cooler? I guess that one might be in use for the turbo. :Q

    Fuel tank showerheads

    I ordered both of the sending units from Amazon. Here are the part numbers to use (for the old dual prong FSUs). Front: FMSU-6DE Rear: E5TFDB The FSU above is for the side tank. Here's the rear tank FSU. Note, I've been doing this project since 1/26. Removing the tanks to service these FSUs...

    Explain Biodiesel for me?

    I've run B20 from the pump before in my Bullnose truck. It runs fine. Here in OK you can get B20 at Love's on the interstate.

    Which replacement injection pump?

    If you already have an intercooled turbo on your 6.9l chances are you won't be able to do many more power improvements without head studs. Check here for rebuilt IPs and IDI parts: https://classicdieseldesigns.com/ https://moosediesel.com/ https://idiperformance.com/ I've ordered from CDD...

    Fuel tank showerheads

    You might consider lengthening the fuel sending unit pickup by a few inches with 3/8" fuel line and a compression fitting. You can use a 3/8" fuel line strainer available at Summit, Jegs or Amazon. I replaced the shower head in my side tank with one I got from Amazon that had the later PSD...

    New 6.9 IDI - Deciding if worth resurrecting or not

    Also, you could check that wire and trace it. Does it go to the glow plug controller on the back of the driver's head, or does it go to the glow plug relay behind the passenger's side battery? Sorry, didn't think to just "Edit" the post first. :frustrate

    New 6.9 IDI - Deciding if worth resurrecting or not

    The Horrible Freight compression gauge works fine. It has a fitting that goes in place of the glow plug.

    CDD injection line issues

    Did you time your IP with a luminosity probe or piezoelectric spark adapter after installing the China injection lines?

    New 6.9 IDI - Deciding if worth resurrecting or not

    I've read that folks use ether to start these IDIs regularly. Just make sure you don't use ether AND glow plugs. One or the other, not together. It should just take a snort of ether if you're using it, no need to dousch it heavily. I have the Horrible Freight compression tester. It works well...

    Explain Biodiesel for me?

    Thanks for the link. I've considered getting into using WVO and brewing some BD, or at least cutting filtered WVO with diesel. I've heard the stories about excessive wear on injectors and IP. Now would be the time for me to do it since I just rebuilt my injectors and have the OE IP (or at least...
