have you checked the fuel pressure ???

So hear is some more ignorance on my part I haven't found a port to check pressure so do I take the return check valve out and tap in there

There is a 1/4" pipe plug behind the overboard breather. You can tie in there, if the plug wants to come out, or you can 'T' into line going in to the block below the #4 cylinder...

Test for static pressure and under load. If you get hose long enough,you can zip tie it to the windshield wiper and drive it around the block.Dont remember the most minimum pressure requirements but someone here will chime in.

60-80 PSI. it used to be 100, but that pressure was blowing out the orings. That plug may fight you, but it is directly in to the fuel gallery.
