I did sneak a look at my friends Ocean Alexander 43's fuel manifolds. He has a SS tube about 1.5" diameter by maybe 10" with 5 threaded fittings welded on to hold 5 1/4" ball valves labeled as follows:
port tank, stbd tank, port Lehman, stbd Lehman and generator.
there is also a similar manifold (5 outlets) which serves to route the fuel returns back to the tank.
If this is what you have, never mind the photo.
Bob Lowe mentioned the desirability of a reservoir but I'm not sure why. Does anyone know why boats seem to employ a tank rather than a series of plumbing tees?
