electric fuel pump GL1100

Post by moewoz »

Hi all:
I changed the timing belts finally ('83 GL1100) so now I can confidently take the bike out for a good drive. The mechanical fuel pump was leaking out weep hole so I looked in to changing to an electric fuel pump. Waited more than 3 weeks for mail order Edelbrock 17303 but never came - so bought an Osias 2-4psi (clone of another Honda bike pump) from Amazon -$35 CDN. It was here in 2 days. Works great! The bike goes like a mother - lots of 'haul' even in lower rpms of higher gears. Unbelievable difference!
Two questions:
1) Because I never rode the bike with good quality mechanical fuel pump, I can't compare performance. Does the electric pump improve higher RPM performance generally on these bikes? The performance change I am seeing now is incredible! No more spitting , coughing etc. around 5000 rpm.
If so, I will keep it. If not, maybe replace the original mechanical pump for the sake of integrity in keeping the '83 looking original. My preference - performance.
2) If electric is the way to go, is there a pump that doesn't make so much noise? This one clicks loudly when running. You don't hear it when driving but when you slow down to stop, it is really annoying ... and doesn't seem to click in any rhythm - faster when you rev up etc. - ruins the beautiful sound of the Wing engine! I see people talk of Edelbrock 17303 (2-3.5 psi) - also K&N (not sure model no. - it is the one with 1-2psi). How do they compare?

I think the '84 GoldWing comes originally with an electric fuel pump. How and why did that conversion come about in the 1984 model? Has anyone used an '84 electric fuel pump on another application. Is the '84 electric fuel pump noisy?

Another question regarding electric installation:
I am planning to tap in to the oil sensor DC power (as described in other threads) for safety cut-off if bike goes over.
How about tilt sensor in Valkerie? Could that be used here?

Thanks for any response/input!!

No difference with a properly working OEM fuel pump, these bikes really can scream down the road. Mother Honda made the mechanical pump with enough fuel output that the carbs would not be starving for fuel at WOT acceleration.

+1 on the oil pressure pump cutoff idea.

There is one benefit to an electric pump. That is being able to prime the carbs after an extended layup without having to use the starter.
