Hi.
We are having an issue with the fuel pressure in my rv7. The engine is an io360 with an fm150. During the climb the fuel pressure is steady but drops gradually and then when running lop the fuel pressure fluctuates between 22-24psi. After about an hour the fuel pressure takes a very sudden drop to under 15 psi. The electric pump increases the pressure to a stable 28, increasing in the descent. The fuel flow and egt also fluctuate so I’m assuming it’s not an indication. The vents seem to be clear, fuel lines are all firesleeved fwd of the firewall and there is a cooling shroud on the mechanical fuel pump.
Has anyone had these issues or know of any fixes?
Thanks
