Fuel pressure woes
I am currently running a TO4E setup on a half bridge.
My fuel system consists of
550pri
1600sec
Rising rate FPR
Tsunami fuel pump
I did have an old Walbaro setup in tank and I am currently just using a piece of hose to act as a siphon in tank where the Walbaro use to be. My Tsunami is mounted forward with the fuel filter. I am using the same stock feed line and return line.
The problem arises when under boost the fuel pressure rises from 43 to 50 psi where it starts to bounce slightly around the 51 area. Eventually it drops down to 43 psi when still under boost approx 1 bar. I check the wideband and I do not lean out.
Would anyone be able to offer suggestions?
