I have been searching thru tons of the great info here but I need some help on a fuel pump issue.
I purchased a 87 GN with a external Bosch pump mounted up above an in front of the tank. I am not sure what number it is. It seems to supply enough fuel although it makes strange noises. Not just loud due to location, but the humming changes quite a bit from low to high etc.
I don't know how the previous owner did the work and I haven't taken the time to drop the tank and look yet.
Should the stock pump still be in there? I think the wire is cut from the stock pump and goes to the Bosch. I am planning on using that wire for the energizing wire and run a heavy gauge wire with a relay to make sure pump gets the best voltage it can. Can you take the stock pump totally out and make a pick up tube to suck up fuel....how is this external pump supposed to be done?
Thanks for any ideas on where start on the fuel project.
