I'm thinking of rebuilding the mechanical fuel pump on my Franklin. Does anyone know if there is a NAPA kit for it (or some other inexpensive part number cross)?
 
What got we wondering is that at full power with the electric pump off, I show basically no fuel pressure.
The engine still ran fine. I'm not sure if this is considered normal or that it points to a weak mechanical pump.
 
you must have some pressure if the engine is running.. how about during climb? engine still running good with no pressure showing?

might just be the gauge.
 
the AC pump was used on Studebaker's

check in Hemmings

2.5 psi is the minimum for the mechanical pump.

use a known good guage to check pressure vs your 3 in 1 instrument
put in a Tee fitting, and use the wobble pump to check the gauge.

I would not fly the plane until this has been done.
