Its been a few days since I've had a chance to work on this problem but I've run in to a road block with this pressure gauge test. I do NOT want to destroy a good hard line that runs from the filter to the IP unless I know I can get another. I've searched everywhere on the web and can not find any one who sells the bolt and fitting.

Is there anyone who knows where I can find one?

I've got the gauge and rubber fuel line but can't connect it to the filter output without a banjo bolt and fitting. That is unless I cut the line that was on there.

I'm gonna try to replace the fuel pump and try another test that way I'll at least know if its the pump.
