Lehman Injector Leak

Motor is a Ford Lehman, American Diesel Corporation variant model ADC 136N. Boat is a Marine Trader 35 Sundeck. Injector is Minimec.

OK, so tomorrow, I am calling Brian at American Diesel for this part. Any marine mechanic expert care to walk me step-wise through the exchange procedure?

I was told by Bob Smith that this is an easy change. But he did not yet say how. I will ask Brian tomorrow. Part is called a "pulsator diaphragm" I have looked it up but have not seen a clear schematic - of the specific part. Lots of the injector assembly, but not so much the part itself. Not sure why.

As I am a rookie at this, I will ask about eight times ("measure twice, cut once"?) until I feel confident to the molecular level. Thanks in advance!

Ben,
That's a knob on the side of the injector pump for bleeding air out of the supply lines when loosened (as I recall). Have you tried tightening it?

Sent same video to Bob Smith of American Diesel. Said I had a faulty pulsator diaphragm. Said it's not common, but can happen. But I will be on boat tomorrow and check it's fit. You do see the fuel spurting out of the center of the diaphragm and a small hole, right?

Ha ha. Yes, pretty dramatic, I know. Has me waiting in the slip on parts. Today was 74 in Carolina Beach, was VERY hard not to cover it with a rubber glove and cruise around. Ah, but oh well.

Greetings,
Mr. B. Just got a note from the all powerful Oz. Was told:

Tell him to take the correct size wrench and unscrew the diaphragm. Screw the new one in. Use fuel proof thread sealer but not teflon tape.
It is not much more involved than changing a light bulb.

I trust this man's knowledge. Go for it.
