Wolf3d Install, fuse amp advice
So far I got 4 relays total for the wolf3d setup. I got a main, fuel pump, fuel injectors, and BAC. The book said to use a 7.5amp fuse for the main wolf3d so I put an inline fuse in. It doesnt say anything about using fuses anywhere else, but I know I probably should. I was considering running the fuel pump and fuel injectors off the same fuse, but I dont know whats better.
What amp fuses should I run for the bac, fuel injectors, and fuel pump?
What amp fuses should I run for the bac, fuel injectors, and fuel pump?

You can figure current flow by yourself...
voltage = amperes x resistance
amperes = voltage / resistance
Assume voltage = 12VDC ...
Low impedence fuel injectors measure about 3ohms.
amperes = 12 / 3 = 4A
Assuming 4 fuel injectors... 4A x 4 = 16A
Use a 20A or 25A fuse.
Fuel pump...use a 20A to 25A fuse, depending on capacity.
Most fuel pumps are fine with a 20A fuse - this covers the stock and Walbro fuel pumps.
If you're running a fuel pump that's supporting over 500hp, go with the 25A (or higher).
BAC is a minor electrical load...
