Fuel Line Removal.

I've got a 92' w250 with bad fuel lines. Is there anything I should know before I start pulling things out? Imagine you're explaining this to a three year old. Are there and big dos or don'ts i should know, I.E. how do I keep from dumping diesel all over my lawn?

Just loosen the gas (fuel) cap and be sure engine is higher than fuel tank. Have a container like a yoghurt cup to catch the fuel in the lines.

Be sure what you're using as a replacement is diesel rated and don't even think about using 15 feet of rubber line- stick with the nylon stuff/fittings or well secured metal

If you have help and a good sized cherry picker it might be easier to remove the bed than to drop the tank. When I had my bed off for paint I replaced all of the lines to the tank including the filler tube rubber which is pricey. Worth the cost though because now I don't have to worry about those lines. There is a return line at the back of the engine as well as the line leading to the lift pump. the other lines from the lift pump are steel and the line from the filter to the injection pump is 2 piece with a rubber gasket at the joint.

If you're considering a piston lift pump conversion get one from Nascar Mark at DieselTuff.com. He has tested his and set them for 14 psi to keep from blowing the seal out of the front of your VE injection pump and filling your crankcase with diesel fuel. That's what happened to me with a cheapo pump I got off Amazon. The cheapo pump put out more than 35 pounds and blew the seal.
