So I have 2 new pumps at $150 each---- before I throw another $200 or so I want to know it's the pump. Just went out and removed emergency pump and put lines back and it started right up with +4 pounds of pressure.
I think I am going to pretend it is vaporlock and isolate all the heat I can, remove antisiphon and retest.
Also before I do that I might put a piece of clear hose and see if I am sucking air even though it runs fine til it's hot.
Water Temps 160-180.
Real nice day to be out. Glass. But still "ground hog day". Still loosing fuel pressure. I have determined its not heat related. I have phenolic spacers on carb and fuel pump. Shielded fuel lines and filter. Engine barely got to 160. Mostly 145-150. Carb, pump and all other fuel related things were cool to the touch. Warmest was the pump... barely. So now I will try the suggested Carter pump.
IM A FORGETFUL DUFUS!
So this fueling issue has been buggin me. Behaves like pump is starved. So ..... I go thru everything again and I start thinking that maybe I got a small hole in the pickup tube and sucking air. It's the only thing a have not looked at because it looked good when I removed the screen from the pickup tube. So I goes to take a look see. I remove the 90 deg fitting and what do I see..... that dam pickup screen. I did remove it to inspect and remember thinking I would leave it out to avoid issues but I must have put it back in. And it was mostly plugged. Now it's GONE. Now to test again and hope this time it's good and I can finish the interior
