Aqua hot leaking diesel
If you are going to do much work on your AH putting those valves in the fuel
line are a good idea. I was worried about the internal integrity of the fuel
lines if I had to keep pinching them with Vice Grips to shut off the fuel. And,
since fuel leaking seems to be a systemic problem (I too have a leaking fuel
pump I am getting ready to replace), it really helps to be able to shut off the
fuel. For a year I have just been turning the fuel on when I wanted to run the
AH and then turning it off when I turned the AH off. I realize that's more
hassle than most people want but as a full timer, most of the time in warm
places, using my AH on diesel fuel is not a frequent occurrence. However, just
to have it right I am going to replace my pump. My fuel lines come down the
compartment wall toward the front of the coach so I mounted the valves there
before they go inside the AH.

If you put those valves in make sure to get high quality valves. The fuel
pressure is very high. The first time I got some at an auto supply store they
told me diesel fuel was no problem but when I turned on the AH it blew the
valves apart. (what a mess) I got the good ones at Grainger.

And also, as Rick mentioned,I put plug in connectors on the four wires under
the left cover (I have been thinking about replacing those four plug in
connectors with a 4 wire trailer connector to make it even easier), so I now can
take the whole unit in and out very easily. Sometimes these units are hard to
get to so it is better to be able to work on it on the bench (and easier on my
old back along with being easier to get tools on it)

By the way, I have great respect for Roger Berke, and he has helped me
immensely. He really knows what he is doing and when he is not close like he
will be at Quartzite, he is nice enough to offer suggestions if you want to
tackle it yourself. And he has or can get all the parts as I recall at a
discount. And when you are working with AH prices that helps.

Anyway, if you don't want to mess with it or if Roger's there, I'd get him to do
it in a heartbeat.

valve in the fuel line, I put the ball valve next to that. While your in there,
you might as well change the fuel line. I used 1/4inch fuel injector hose for
that, available at most auto supply stores.

quality bullet connectors to the wires which connect the burner to the main
unit. Lee Davis told me this trick. Now when I need service I turn off the fuel,
remove 2 nuts and unsnap the wires and I can take the burner out and work on it
on a bench, instead of working on it in the torture chamber!

rebuild on my unit. where did you install the 1/4 inch ball valve at in the
system? Thanks for the info.
