 |
|
After way too many years building, today we finally started the Lycoming 0360 in my RV8A
I have the standard Vans steam gages and the fuel pressure gage never made it into the green with engine running and boost pump on or off. (same for engine off and boost pump on) gage off the peg but not in the green.
Fuel delivery test shows good delivery flow - 26 ghp.
Could this be a bad trasnducer or what have others in the group found to resolve this?
I have checked the listings and not found a good answer.

Could you have the gauge intended for injected engines? Are there any
numeric values?
The correct gauge shows green from 0.5 to 8 psi and max value of 15
psi. With the flow you have, either you have the wrong transducer or
wrong guage or both.
Current catalog shows IE VFP 15 and IE 411AB transducer.

Yup, that the gage, will check transducer numbers Spoke to a friend in Florida, he cracked the line to the transduser and bled out the air.
