90 7.3 fuel injection problems
I always test stuff. I have a bunch of videos on youtube under onecraftydude that is almost all building and testing different fuels. I am surprised I didn't find a piece of copper sticking out of a bucket of veggie with green crud on it. I know copper corrodes green so it is corrosion most...- robert bley

90 7.3 fuel injection problems
I put some bio con from NAPA in the tank and it is getting better. I wonder if the green you were seeing in the tank was not algae? This stuff is formulated for bio diesel and it fights algae so it would make sense to me. I will switch my plumbing out with stainless now that I know there might...- robert bley

90 7.3 fuel injection problems
I will keep that in mind and maybe switch to aluminum. I didn't think about the acids in the fat reacting with the copper. I need to pull the front tank and replace the guts so I will check the inside for crud and clean it before I replace the sensor and pickup. What do you think about coating...- robert bley

90 7.3 fuel injection problems
tank heater I use a fuel line heater. I just ran copper pipe from the pump located just in front of the front fuel tank on the frame rail. The copper pipe wraps around the exhaust pipe all the way up to the manifold and is wrapped with exhaust tape. The output temp of the fuel gets around 110...- robert bley

90 7.3 fuel injection problems
I use regular diesel every night since I switch tanks before I shut down, usually a few miles from home. When I start up it is always on diesel. If I have problems with it running I always run diesel in both tanks until the problem clears or I fix it. I only supplement with wvo for the longer...- robert bley

90 7.3 fuel injection problems
WMO vs WVO I just wanted to clear something up. I am using waste Veggie oil. I have noticed some crud around the filler neck and I figure that is what is in the injector pump too. I always use one tank for veggie and one for clean diesel. I start and stop the engine for a few miles on diesel...- robert bley

Thanks I apreciate the quick response. I have been reading all day and learned a lot. I have had this truck for 12 years and had the engine rebuilt when I bought it. The IP was new and I never messed with it until recently. I have had problems before with glow plugs going bad and had to...- robert bley

My 91 F350 dies when I down shift. I have been using vegetable oil as a fuel for a year or so. I have had some bad veggie in the tank and had problems with the engine starting. The last time this happened I replaced the fuel filter and had a heck of a time bleeding the air out of the lines...- robert bley
