1956 johnson 5.5 fisherman single hose

my 56 johnson 5.5. i did the fuel pump conversion and it seems to work very good! used a universal briggs and stratton fuel pump.

How did u convert the fuel system? Need a video

Pull intake. Install a small rubber plug on one of the pulse valves. Use the vacuum to power a generic fuel pump. Swap out fuel attachment on motor.

She sounds happy. Nice job.

[@VintageOutboardMan]

runs really nice! you gotta love these old motors :)

[@dkonrai]

thanks vintage. wondering if i can get a buyer for this? motor runs better than most new 4 strokes.

[@brandonmichael230]

i really dont know the answer. i just bought a universal fuel pump at the lawn mower shop. told the parts guy i had a 5.5 hp motor, and thats what they gave me. its a universal briggs and stratton for 20 bucks. then i had a spare fuel connector, and a 1/4" vacumn plug.

I was wondering why not use a low pressure electric pump?

[@bengorrod6061]

Hi I'm trying this at the moment on the same motor just wondering what part you used for fuel connector? from the hose to the engine struggling to find something at moment

[@dkonrai]

i used a standard omc fuel fitting. remove the old one. u need to block off one of the ports one the intake to create a pulse for the fuel pump.

[@dkonrai]

conversion was really easy. took off the intake, removed the check valves, plugged off one of the outlets and viola, i have pulse for the fuel pump. pump was cheap too. going to try a 7 dollar fuel pump off ebay on the next one.

[@dkonrai]

yes thanks. it runs surprisingly well.

[@fleetwin1]

Running/pumping great but please raise the water level in the tank

[@dkonrai]

there was more water in the tub it just kinda sloshed out while i first started her up.

[@coalbear1]

BTW what is the fuel pressure required for a 57' 7.5?

[@outboardfun3353]

the water pump needs to be under the water at all times when running in a tank, bucket etc.

[@brandonmichael230]

the fuel pump works off a pulse from the motor. as the rpm increased so does the demand for fuel. a electric might over take the needle valve. the conversion is one that is tried and proven.
