iirc he's reported averages of 80% to even 100% at times. and he doesn't have a secondary tank for startups/cooldowns.Mel, what percentage of WMO to diesel were you running?

I have a f350 91 7.3 n/a 4.10 5spd 7300lbs 3in exh, it has newish bb code injectors with 15,000 kms on them, and now a rebuilt 5070 turbo calibrated pump. The compression is good with the lowest 400 and the highest 450. The power with the new pump is quite a bit better off the line but it pulls hills the same as the old pump (85 kph 6% grade unloaded). When I put new injectors in and even the old ones it would pull the same hills easy. The new pump also smokes black at about 1/2 throttle, anything over that and it will cover a small car in smoke. It has been losing power since i started running wmo in it at about 50% diesel and 50% wmo with 75/25 diesel gas mix so not much gas. Ive probably ran about 400 litres of the mixed fuel through the engine since June. I work at a shop so when someone puts alot of diesel in there gas vehicle I just burn it in my truck. I thought my pump was shot so I put a rebuilt one on, and not much change in power. Could have the little bit of gas ruined my injectors or could my pre cups be coaked? Also the truck runs great with not much smoke when cold. I am also running pure diesel since I put the pump on.
I just pulled the injectors and the pre chambers were coaked up bad. I had to chip the carbon away from all 8 of the injector holes. When I pulled them it was the same as before, the injector holes were closed up by carbon, with only a tiny hole for the injector tip. After I had done that the engine sound changed dramatically, and the power has returned. The engine now has a deeper rattle, alot smoother idle, and is more responsive. Thanks for the help.
I'm expecting to find as I had once before, the same situation with the injectors as was reported a few post earlier. The pintle is about the only thing that may be protruding through the hole. Still looking for a calendar date to get to this.
