I have a 1973 85hp evinrude, on which the furl pump crapped out on me. I was going to replace it with an electric fuel pump. I can get the electric for half the price of the factory pump.
Now, my question is, what PSI should the pump be pushing? I called a local boat shop, n they recommend 1-2 PSI. They said more than that, the pump will force fuel through the carberatur at a much faster rate than the motor can burn, and it will run really rough or not at all.
I'm having a hard time locating a pump with such low PSI. I see them for around a 3-5 PSI range, but not lower than that.
Also, what about the flow rate? A local parts store has a pump that pumps 28gpm(or GPH?), can't remember off hand, but it don't mention the PSI behind it. Which number should I be looking at, the flow rate or the PSI? N what would be an ideal number?
