803A Hard to start

[jamawieb]

So out of curiosity, was the hard line plugged near the Banjo fitting and no fuel is passing to the metering pumps? Or are you saying the tube is clogged near the far end and the fuel can not reach the bypass that goes up to the injector returns? If you are only talking about the bypass to the injectors, I've seen several that were blocked off, but not with junk, they appeared to be blocked from the manufacturing process, possibly with brazing or something as I had to drill a tiny hole through the end. Not sure if it is supposed to be sealed off by design or not.

It was blocked somewhere in the middle of the tube. I could not blow air through the end starting at the return line and could not blow air through the 1st 2 rubber lines closest to the return line.

Well thanks to Rich and Jimmy I got my 803 Generator back home and working. I picked it up last Sunday. They are both really good people. Thanks again. Jim

Got around to cutting it open. Looks like it was mainly blocked to manufacture process and then rust closed it the rest of the way. It was between the 2nd and 3rd line.

It would never have rusted if it had not set so long correct?

Hard to say. If some fuel had a lot of water in it, it would cause rust quickly. Mainly clogged due to the manufacture process.

A properly maintained gen set will never have water that far into the fuel system.

Were those joints welded or silver soldered?
There shouldn’t have been any accumulation between the two joints. If it was welded it should’ve been right at the joint.

I've never studied this hard line that closely, but its possible that its a brazed assembly (which could cause for minute amounts of material to flow through the joint and down into the tube.

I could be wrong. But I thought Brazed.

You guys are correct, they are brazed, or at least all the ones I've looked at that closely were brazed....

Yeah they would have to be tigged or braised
