......Priming a Bus is an artform, I have learned!!!!!!!.........Finally....... I think I got it.
So to figure out whether it was my pick up tube in the tank or the fuel line, i disconnected the fuel lines on both ends and blew air through it to make sure I had the right one. Then I put the line going to the #1 fuel filter in an empty bucket and hooked up a 12V fuel pump on the other end. It took several minutes for the fuel to make the journey. Once I had fuel coming out I hooked it up to the fuel filter and unhooked my pump and put my line in a bucket. And wouldn't you know it, the bus ran like a champ sucking the fuel from the bucket. I shut the bus of and carefully hooked the line back up to the tank thinking I had just eliminated the fuel line being my problem. I figured it had to be in the pick up in the tank. But guess what? I hooked it all back together and wouldn't you know it. PROBLEM SOLVED. It needed to be primed but I guess priming it in the back as I had been doing just didn't cut it. I had to prime it from the front at the tank.
SO what was my problem, was it the fuel pump? I replaced it. Or was it pilot error. I had forgotten that I took fuel out of my tank to put in my tractor (about 5 gallons) the old fashion way, hose in tank and suck and let gravity flow due the rest. Now I wonder if maybe that was my problem. All along I was doing all this trouble shooting when actually I may have created the problem myself.
. I will never know I guess, but just in case I don't think I will be siphoning any more diesel out of the bus for the tractor......
I am one happy bus Nut. At least until the next problem comes along.
