I just returned from a cross country from Dallas to my home field in Florida in my RV6A with a 320. Crusing at 9,000' ; 2400 RPM from time to time the fuel pressure would dip to 1 psi, I tried to trouble shoot and could get the pressure back up by either turning the elect fuel pump on or richen the mixture. Oddly enough, and it may be my imagination but an hr our so later when the tanks were about 1/2 full the presure was about 5psi and leaned. I've spoken to others that have seen the same issue; unfortunatley no one knows why. I've checked the vents and found no obstruction. All suggestions are appreciated.
