Hi, I have a 1987 gm 4.3l merc 2 barrel carb.
I need to buy a new electrical fuel pump but don't know which one I need. I am looking at one that has 30gph and 2.5 - 4 psi. I was told that this would be fine because most carbs. like running at 3 - 4 psi. Actually I was told this would be perfect.
Are there any performance advantages to go to a higher psi like 4 - 6 psi.
What is the difference in marine and auto universal fuel pumps.
Thank you all!!!
