Gentlemen, A little follow up so far. Several of my pressure tests have been misleading. Sometimes they appear to hold and other times not. I guess it depends on where the fluid is moving arounin the system. I have not been topping off the reservoir with boiler fluid because it is getting expensive.
Steve made the right call. It was not the line that was leaking, but a slow drip at the hose fittings at the heat exchanger. Found a couple loose hose clamps on the rubber right angle boots connecting the plastic hose to the exchanger. As a note, I did find a good selection of silicon hose 90's that could be trimmed to fit if required to replace the boots at our local industrial hose supplier. I did use coast guard approved marine hoses.
So I have tightened the offending clamps, no easy thing, and am now in the process of pressure testing to confirm pressure integrity.
I have replaced the Racor filter and replaced as many associated burner hoses as I can. Unfortunately, I can't get access to the top of the diesel tank to replace that hose to the Racor filter. So I have left it. It's rock hard. My problem now is that diesel is not gravity feeding into the Racor filter. I have purchased a primer bulb to give it a try. If that doesn't work, I will try to apply pressure to the diesel tank. Any and all ideas will be appreciated.
Respectfully,
Mike Sulley
