I moved this from the multihull
section; maybe i'll get a response here.
I know there are many threads about fuel
polishing systems, but I haven't run across answers to the following questions.
Considering I have a 1984 35ft. Witness cat, with a 17ft. beam and I'm putting the polishing system in the port rear berth:
1. Will I have issues with the starboard engine
starving for fuel
? The engines are 13hp Nannie diesels. Would a typical fuel pump
be able to handle the extra distance, or would that be straining it?
2. Would I need check valves in the system?
3. Should I include an in-line fuel pump
to ensure the starboard engine
will get plenty of fuel, or would that cause problems?
The polishing system I built brings the two tanks
together to go through the polishing filter and pump, but each tank can be isolated in order to polish the fuel and return it to its proper tank; or I can move fuel from one tank to the other, or bypass the polishing system all together.
My concern is the extra distance I'm creating for the starboard engine. I'm also moving all filters to the polishing panel to ease maintenance
; except the filters on the engines, of course.
Would running the fuel through the polishing system while under way cause any issue? This would basically mix the fuel from both tanks
, and then split it out to both engines, but the polishing pump would certainly alleviate any issues about the whether or not the starboard engine fuel pump could handle the increased distance...
I'd appreciate any assistance in this matter.
