1992 40hp Johnson Fuel Flow Problem

[cubsr1st4ever]

Our engine is having some trouble, we have diagnosed it to be the fuel pump, but that isn't a forsure, perhaps u could offer advise on how to fix it or other possible reasons why it would be doing this.<br /> When you start up the engine it rev's extreamly high and then dies. When we start the engine and I pump on the bulb it will continue to run but not very well. If you could tell us how to repare the fuel pump where to find it, and how to get at the carbarator that would be most helpfull. Also where we could buy a fuel pump for this engine. I saw a fuel pump here but i'm not sure that that would fit onto our engine. <br /><br /> Whatever help you can offer would be welcome!<br />Thanks<br />Ben

same answer i put in quatro4444's post.

OK before you do anything else, let's find out exactly what motor you have. model # on port side of transom mount, or one the Freeze plug on the top of the block. this tell us what you have.

if the pump is bad, my recommendation is to go to the premixed fuel pump, that is block mounted, it is a very simple conversion. you remove the vro pump, block the pulse line, and reroute the incoming fuel line to new pump, and reroute the outgoing line from new pump to the fuel line splitter. you use this pump. http://www.iboats.com/Sierra_18_735...z.36857--**********.824329505--view_id.174141

this pictures is a 1993 40hp with new pump.
