Speedster 160 fuel pumps
Posted 08 October 2010 - 08:15 AM
I was wondering if a electric DC pump could be used successfully.
Wondering if there is any reason why it would not work.
What is the GPM fuel delivery of the stock fuel pump, and as the OEM fuel pumps are diaphragm type delivering fuel in a "pulse", would a consistent fuel flow delivery from a DC pump present a problem to the carburetors?

I have never done so, but in my opinion I would stick with the OEM fuel pumps to be safe. Keep us posted if you decide to take another route, thanks!
I have not tried to use any alternate fuel pump arrangement yet,..I did overhaul the carbs and took the boat out for a test last Friday....no joy on the Port engine (the starboard engine is running just fine)...it is even worse, than before rebuild. The engine will not hold high RPM...just oscillates from say 6K rpm to less than 3K...this is all without touching the throttle (other than to have already advance it to full throttle position)....Something I did not check (I know dumb ass!) is fuel delivery which could explain why it idles OK but will not hold high RPM (bad fuel pump or clogged up filter???).....Historically the Port engine always started & run with difficulty than the Starboard engine...it has always been a bit of a little bitch compared to the starboard sweetheart.
Is there a rebuild kit for the fuel pumps?
I am not even sure there is a fuel filter in line with the fuel pump on each engine.
Any ideas guys??
