[darkien]

hi im new on the forum and is from sweden so my english is a bit rusty

i resently bought a 10 hp sportwin (not shore about the year but i guess 1956-58) and want to convert it because its a
huge problem to find an old pressuretank in god condition......

i dont really know what to search after but i want to convert my engine from pressure system to modern system with fuelpump an read in a other tread vhere they used briggs and stratton fuelpump the question is from vhat engine should i take the fuelpump

and exaktly what does i have to modify is it just bolt on a fuelpump connect the fuelline from tank to intake and a fuel line from output to the original intake and then the pressure line to the pump insted of to the pressuretank or is anything else i have to modify

hope someone kan uderstand my poor english and have som answers

cheers /D

Nahhh, you did just fine. I can understand you. I think it would be much simpler for you to buy a fuel pump and bypass cover, from a 1960 model Sportwin and mount it up. No modifications, and it's a very simple, factory conversion. Sure there are lots of Mikuni fuel pumps out there and people like them, but I think the factory set up, is much simpler and much less modification to do.

hi,oledan here.
i also have a 1956 sportwin 10.to convert it to a modern well working outboard.i simply put an electric fuel pump on it.ran a toggle switch to the pump from my battery and done.i think the maximum pressure from the fuel pump is 7 gph.i use this thing alot too.i fish alot at night so i needed a battery for lights anyway.and i seen the same little pump on ebay for 30.00 bucks i think.

Electric fuel pumps are usually not recommended for these old, non-computer controlled two strokes. There is no (easy reliable) way to shut the pump off in case of a stuck float (happens often), split hose, etc. The pump can fill the cowl up with gas pretty quickly.
Just because something works under perfect conditions doesn't mean it's a real great idea....which is one reason they got rid of the pressurized tanks in the first place.

Yikes, sounds like a dangerous situation waiting to happen. I wouldnt do it, nor would I reccomend it. Under the right conditions, its a firebomb waiting to happen.
