Re: fuel pump change over
i just did my 2004 50 Johnson, the reason, i keep getting oil siphoning, into the carbs when it sat, on a potoon boat, and tank was a good bit higher than motor. so i went with a straight fuel pump. BRP # 433387, or 438556. you can also use the sierra pump #187352 which is 1/2 the price as BRP
http://www.iboats.com/Sierra_18_7352...view_id.174141 remove oil line, and tank, disconnect harness to tank, and vro pump.
there is a plug on the side of the motor (starter side) with 2 threaded holes. this is for the straight fuel pump. remove the plug, and besure to get the gasket between the block and the pump. 2 mounting screws. then just plug the pulse line. i just use a bolt that fits the hose and a hose clamp. fuel in goes to round part, fuel out of the housing base.
