Have you verified the gauge is reading correctly?

Subject: [WanderlodgeForum] 8V92 Low Fuel Pressure


I changed seven fuel lines...4 at the heads, Racor to fuel pump, fuel
pump to filter inlet, return manifold to hard return line.

After priming/starting the 8V92...Fuel Pressure readings were 8 at idle,
45 at 2150 rpms. Ran the engine for a few minutes. Fuel pressure now 2
at idle, 30 at 2150 rpms. The manual says 20 to 30 at idle, 50 to 70 at
2150 rpms.

A new fuel pump was installed. Same low pressures as above.

Removed the pressure relief plug, gasket, pin, spring, relief valve,
from the *old* pump. All looks good, nothing stuck.

My error, I did not take fuel pressure readings before the hose change,
problem could have been there before.

Thoughts?
