I have been having problems with fuel pumps for a while-didn't know what the problem was? Found some guys in Chatham Ont. who weren't afraid of my wiring- they put in a new bosch pump let it sit for 20 min. on the ramp and then I drove it about 50' and it died. They figured there is a short in the wiring and didn't have the days time it would take to find it. They ran a new power wire from the fuse box back to the three wires coming off the pump. And now it runs great but I have no fuel gauge. They told me the gauge runs on about 3 amps or volts don't remember. They said pick up a new sending unit and start from there. Question does anyone know if any other sending unit will work. And I guess how to run a power wire with the right amount of current to run my gauge. Or any other ideas how to get my gauge back- thanks for any help. It certainly is nice that it is running again- writing down my milage-ha ha
Your sender uses 12v. When they ran the new wire they left your sender unhooked. You need to find the line in and out on your sender, hook power to the in line and jump the out wire across the plug. Unless the short is in your sender or gauge that will get it working again. You may even get away with just putting jumper wires across the 2 lines in the plug if your gauge runs off a different circuit, witch if I remember right it does.
