The valve you see is to seperate or combine the two tanks as needed.

I’m not at my coach right now, but I don’t think I have two separate tanks and I only have two fill ports one on each side

[Richard]

when I opened the banjo style bolt and hit the little lever I get fuel coming out of the lines. It’s only when I try to open the hard lines that I don’t get fuel at the fuel rail

I realize how hot it is in San Angelo. I lived there.

Your statement above may be crystal clear to you, but not to me. When getting internet help from the gurus, the more specificity you can post the better the response will be.

Answers to the following questions may help us help you.
How much fuel is in the coach? If the gauge is inoperative use a stick.
Can you be specific about which banjo bolt?
What is the little lever you describe, is that the fuel cutoff solenoid? If you do not hold the fuel solenoid OPEN you will never get fuel to the injectors.
Were you cranking the engine when you cracked the nut at the injector? Were you holding the fuel solenoid open?

If you look at the top of the fuel filter, the white star shaped knob is a priming knob. Unscrew it and pump like mad.

If none of that works. Let’s go to basics. Diesels are simple. If it doesn’t run at all it is lack of fuel or lack of air.

Let’s trace the fuel. Start at the fuel pump and remove the discharge line. Does it pump fuel when cranking the engine? If so…..
Replace the line and keep going at each filter and junction till you get to the injectors.

It’s not flowing for a reason, and

Not currently at coach but first two pictures are of the little pump with the lever. third photo is the banjo style boat on the return line I believe. It’s the line closer to the front of the gen. when I loosen that I hit the lever until only fuel is coming out. at first there was tons of bubbles and fuel mixed. then I tightened it back up and un loosen the fuel rails. To see if fuel will come up there when I hit the starter. I have tried holding the solenoid in as well. I have not confirmed if it’s getting power.

I have NO idea what the lever on the fuel pump does. But I am sure it is NOT the fuel shutoff solenoid. Hold that solenoid open by hand while cranking the engine.

The lever on the side of the round shaped pump is the prime lever. Pumping that will help purge air . You were correct to do that.

Richard,  she has a mechanical lift pump running off of the injection pump cam.. She also has fuel although I can’t verify if there are two separate tanks like on the pre 90’s coaches. The banjo referred to is the “out” of the injection pump so if the fuel is coming out at that point , then she has fuel enough in the injection pump that there should be fuel at the injector hard line outlet which there is none reported.  This thing has been sitting for a very long time, maybe years, so it is reasonable the delivery valves may be stuck.  

We talked this out over the phone and used FaceTime to verify locations and procedures.  What I don’t know is if the fuel quantities “coming out of the banjo” are consistent with what I determine to be adequate flows.  Drea is a trooper and is not afraid to try anything, asking good questions is one of her attributes.

The local Yanmar knowledgeable equipment dealers should have a technician that could resolve the non starting condition.  I would try that avenue first.  Dean posted a couple of dealers close by.

You are an absolute saint Gordon I appreciate you time and expertise!!!! Thank you so much ? when I get back to the coach I will try some more options. I’m trying to avoid the heat and find a place in Texas where I can move the coach indoors so I can actually do things. That 100 degree heat is no joke hahah. Hope you’re doing well over there chat soon

[Richard]

Thanks Gordon!!!!

Hang in there Drea!
