Title: Bosch 044 pump in stock wire harness?
Post by: Kuma 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?

no one, don't you guys run external fuel pumps on the big turbo motors?

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

all of the busa turbo kits we do use factory wiring/relay with a 20 amp fuse.

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.
