Naw. Not a fuel issue. Have it set up to where it starts at 60 and raises to about 80 with higher rpm. I have a nice bottom sump with mazed in baffle setup. 1/2” lines. And i had 3/4 tank of fuel. Definitely not a fuel issue though. As i would climb the grade to test it, i was literally coming up to 60psi then slowly trying to roll past it when it would drop and surge.

Only things I’ve touched since it was fine on the way home: removed and reinstalled the intermediate pipe and v band clamps. Supplied air pressure from 0-90psi a couple times up and down to the afc to make sure there were no leaks. Then hooked that back up. And moved the anti surge ring out .125”. Everything else was left the same.
