    Has anyone ever tried maxing out cetane boost in synthetic WMO to avoid friggin' around with the timing?

    Im not an expert either, lol. But from what I've read by raising the temperature of the fuel prior to injection its makes for better atomization and thus better/easier combustion. If you use a heat exchanger that uses engine Coolant you could raise the temperature of your fuel by over a 100f...

    Bought a new truck, cant get it started. No fuel coming out of the injection pump.

    Thank you for the suggestion, I tried it. However it did not work. Previous owner claimed it was running good until he had a shop put a new transmission in it. It doesnt crank with the key, only from the fender solenoid. So I figured the shop messed up something somewhere in the starting...

    Would preheating the wmo accomplish the same thing as raising the cetane value?

    Bought a new truck, cant get it started. No fuel coming out of the injection pump.

    That's what I thought but wasn't certain. No, I am not getting fuel out of the IP. I did verify it that way. The metering valve rod/bar moves freely. Im soaking the IP bowl with some power service diesel kleene. Maybe that might free something up? If no luck with that I think ill either try...

    I get fuel into the IP. Cracked the feed line at the IP and fuel comes out when the lift pump is on.

    Bought a new truck, cant get it started. No fuel coming out of the injection pump.

    Just picked up a 1994 f350 with 7.3 idi turbo. I bought it knowing it didnt run. Its a crank no start. I am not getting fuel out coming out of the injection pump to the lines. I verified that fuel is going into the pump by removing the feedline. The FSS solenoid does work, I removed the IP top...

    Engine making a "knocking" sound and whistling from the exhaust. What things should i check?

    Forgot to add that. Yes I did that prior to pulling the injectors and cleaning them. The sound didnt change when doing that. Can air intrusion cause this kind of sounds?

    Engine making a "knocking" sound and whistling from the exhaust. What things should i check?

    As the title says, my truck has started making some noises. Its a 1991 f250 7.3 na. Here's a video put i together with what it sounds like I popped tested the injectors and they all tested at ~1600psi and had good spray patterns. I know that is really low but its not quite "bad" either. One of...

    Heres how I added an additional fuel filter that reuses the engine oil filter.

    I had considered that filter, primarily for the heating aspect, but then I saw the price tag and said "ouch". If i find cheap used one I might try it out also. BTW im running 85-90% wmo though

    Heres how I added an additional fuel filter that reuses the engine oil filter.

    I know its not free for everyone, but it essentially is for me. People are willing to pay for pickup of large quantities of used oils around where I live. That money I use to buy RUG for the dilution. As well as there are also people selling super cheap and giving away free "contaminated"...

    I dont know. That's why im adding this extra filter in front of the stock filter. I've been using the motorcraft fd3375 which is 10 micron. I ordered some wix equivalent filters to try those out, 2 for the price of one motorcraft. Its part of the experimentation

    Heres how I added an additional fuel filter that reuses the engine oil filter.

    Who said anything about raw fuel? Its being filtered multiple times. Obviously its not cleaning as well as a centrifuge would, as evidenced by the stock filter clogging so easily, but i dont have the space to set up a centrifuge. So I have to use other methods for now. Do you not understand that...

    Dude what are you on about? Who said anything about raw wmo ? Maybe if you would do some reading you would understand what is being talked about.

    Yes the stock filter is rated for 10 micron and its still there.

    Heres how I added an additional fuel filter that reuses the engine oil filter.

    Even if it were the burn up the pump and injectors every 50k miles it would still be worth it for me where I live right now. 50000mi÷~15mpg=3333.33gals of diesel × average of 4.5$ gallon= 15000$ to drive that 50k miles. Im pretty certain I can get an entire fuel system for this truck for less...

    Heres how I added an additional fuel filter that reuses the engine oil filter.

    The repurposed oil filter is in front of the lift pump. I did think about the possibility of extra stress but I decided to try out anyways. I dont really care if it burns up the lift pump as I dont like it that much and would like to upgrade to the holley red lift pump that I have read about.

    Heres how I added an additional fuel filter that reuses the engine oil filter.

    No. I first filter through 3 polyester paint filter bags in a 5gal bucket directly into a 55gal barrel, 10->1->.5 micron. That barrel has a pump with a 10 micron filter on it which i then pump into the auxiliary tank in my truck bed. The auxiliary tank pump also has a 10 micron filter on it...

    You cant ask why after saying TLDR. If you would read it I explain why and my thought process.

    Heres how I added an additional fuel filter that reuses the engine oil filter.

    I added an additional fuel filter that allows me to reuse the engine oil filter after an oil change. After clogging a handful of the stock fuel filters on my truck I decided to add an additional filter that uses a cheaper filter do to the majority of the filtering. I cant afford an oil...

    Zf5 inspection without fully tearing down?

    The fluid was only a few thousand miles old, but it was extremely clean without any trace of metal in it. Even the fluid i drained from it when I first bought truck a few thousand ago wasn't very dirty and didn't have metal in it either

    Zf5 inspection without fully tearing down?

    That's what I thought it would be and what I experienced with the previous transmission i worked on. However that previous transmission the input shaft would move axially, this transmission the shaft does not move at all.

    Zf5 inspection without fully tearing down?

    Is there a way to inspect a zf5 without disassembling it? I dropped it since it was making lots of noise. It would whine and growl at idle with the clutch pedal released. Sound would go away when clutch pressed in. Now that its out it clearly has a bad clutch release bearing. What's not clear...

    Disappointed in the Facet Duralift electric lift pump for running wmo

    Ive got clear vinyl tubing between the facet and filter and on the supply line to the facet. I dont see any bubbles. Only after the truck has sat for little while but once its running they are gone. I am running a higher percentage of wmo than you are. I probably will have to go a higher...

    Disappointed in the Facet Duralift electric lift pump for running wmo

    Installed the facet 40223 9-11 psi pump on my truck. I have to say I'm disappointed with its performance. I find that it cannot pump enough when running on wmo. Im running a blend of about 85% wmo and the rest diesel. Under moderate to heavy acceleration the fuel filter light comes on. Even on...
