Does anyone know where I can get a solenoid shut off mounting bracket or part number for my M939A2?

Thanks. Problem with that is the tank is full. Avery heavy job including opening fuel lines to accommodate that. Think much easier to use a hole saw above tube.

I modified a fuel cap

Thanks, I thought about the pick up tube. What a headache that would be on this truck.

FYI, I started out with 20 psi then 40 & 60 psi. I could not get flow out of the line I broke open under the loft pump. That is why I put 100 psi in. There maybe a problem with the line not sure. Thanks

Thanks for the info. A replacement pump is being sent. I'll take a look at the one I remove.

It was a small compressor and a full tank. 100 psi was momentary

With a full tank of fuel there is little space to apply pressure. What found is the new lift pump is defective.

Thanks for the reply. This may suprise you but I turned up compressor to 100 psi. That allowed fuel to flow through the line up to lift pump, but from that point on I was unable to get flow coming out of injector pump bleeder screw inspired many attempts with compressor. I have to figure out...

I have broke open fuel line below the lift pump and applied 40 psi to the tank which is full, yet i don't get fuel flowing from the open line. Any suggestions on what may be the cause? Thanks

Good job, I ordered the gauge. Thank you .

Thank you. Is there a good place to hook it up under the hood?

Thanks, that sounds like the problem. I just ordered a new lift pump. I do get alot of white smoke now.

I wonder if the lift pump could cause a no idle?

Thank you. I will try a pressure test.

Thanks, I have done that.

Thanks for your input. I replaced FSOV with a new one. I replaced fuel pressure valve as well. Engine issue has me stumped.

FSOV is what part please?

Thanks, I'll check it out.
