Fuel pump resistor

[Cam]

So my car decided not to start on me again today, after resetting my timing belt and installing a new tensioner. I could not hear the fuel pump kick on, so I started digging around. I got 10v at the pump, which seemed understandable since the wiring is almost as old as I am. I decided I would see if unplugging the resistor would help. So I unplugged it and BAM, car started without a problem.

I know I should probably not run the pump without the resistor, but a guys got to do what a guys got to do to get to work. However, the only thing it says on it is A15-000R20, and I cannot find the part number anywhere.

I also plan on replacing the pump just in case soon, and will probably go with the wahlbro (I probably butchered that spelling).

Thanks in advance for the help, guys.
