Bosch 044 pump in stock wire harness?
« on: December 18, 2017, 02:45:44 PM »
how many amps will the stock wiring handle on the fuel pump? do I need to add another relay for an after market pump?

I always use a relay on external pumps.  If you have to increase the fuse size, then you really need to use a relay.

Absolutely add a relay
Nitrous is like a hot chick with STD'S...You know you wanna hit it but your just not sure of the consequences.

I put an external relay on controlled by the stock fuel pump signal so it acts just like it should but I don't have to worry about over taxing the wire harness.
