I am relocating my fuel pump on my '73 to the front of the car. I am feeding the wire off the fuse panel but also want to add an inline fuse. Does anyone have an idea of what amperage fuse I should run between the fuse panel and pump? The pump is a Pieburg

The pump is a Pieburg Better to run from the original supply so you retain a relay and original fuse,if you don't you will need a 7.5amp close to the switched supply ,I ran a wire down the tunnel into the engine space and connected to the original supply. |

I'm running my front Pierburg type pump to a dash switch, then to #8 or 9 fuse. That way, I can turn on my power without the fuel pump running on the whole time.

So you don't have an additional fuse between the fuse panel and the pump? I am doing a six conversion as well so I am not retaining the relay board. |

the 911 3.2 pump is protected by a 25A fuse
maybe worth looking at these threads http://forums.pelicanparts.com/porsche-911...fuse-issue.html http://www.914world.com/bbs2/index.php?showtopic=113517 QUOTE(mmascari @ Jul 3 2017, 08:30 AM) QUOTE(Larmo63 @ Jul 2 2017, 02:05 PM) I'm running my front Pierburg type pump to a dash switch, then to #8 or 9 fuse.
