Have to start thinking about the routing of all the systems before the construction of the furniture starts.
The fuel tank
is to be mounted on center just in front of where the mast
would normally be, between the forward cabins. This is about 6 meters forward of the engine
compartments. The 20 hp motors are about 6 meters apart in each hull
I was thinking of a pair of Racor
500MA with a changeover valve mounted to one side in the seating across the aft main bulkhead. This would give a feed length of about 9 meters to the filters then about 7 meters to one engine
and 3 meters to the other, seems a bloody long way. The top of the filters would be about level with the top of the tank. I could install the filters in the aft head
which would shorten the runs by about 2 meters and they could then also be mounted just below the tank level.
There are many cats in the same situation with long runs so I may be fussing about nothing but
Should I run bigger lines
Maybe a pump to prime the long runs
I was thinking of running the fuel
return lines only back to the inlet of the filters
Access to the tanks
will be somewhat difficult so a shut off valve at the tank may be problematic
