Re-doing Fuel Hose Rigging on Twin Engine Boat
Posted: Fri Dec 10, 2021 4:59 am
I recently acquired a 1987 Revenge [later disclosed to be a 22-foot hull] with twin Yamaha 70-HP Precision blend two-stroke-power-cycle engines. The fuel tank rigging originally was two hose barbs with a separate hose to each engine. Some of the hoses and parts are there; some are gone. I also received a box of mismatched parts. Since the fuel hose rigging is a mess, I am ready to redo it. A nice buddy's opinion was fuel hose rigging would be kept the way it originally--two separate fuel lines.
Q1: should the fuel lines be rigged as follows: one large diameter hose to a fuel-water separator filter from the fuel tank; then two separate hoses to each engine from the fuel-water separating filter?
ASIDE: I don't know if I can make these older Yamaha engine run and last. I may have to re-power. If I were to re-power the 1987 REVENGE [of unspecified length] I would use a single engine. If that occurs, then having installed one large hose from the tank to the fuel-water separating filter will save me from having to re-do that part of the fuel hose rigging.
Q2: in your opinion, how would you re-do the fuel rigging?
Thank you.
