I think it is better to setup the vipec to drive the signal to ground, only aux 5 and 8 can be used to drive the signal up, with

limited current, so better to use gnd driving.

pin | signal

85  | battery via fuse

86  | Vipec

87  | pump

30  | battery via a fuse

here is my setup for the second fuel pump, connected to aux 2


this is the extract from the manual

thanks for the help guys this appliction is for an outright drag car running a fuel cell and 2 bosch external fuel pumps with 2 relays with the v88 vipec


alright, good luck and please post pics :)

I decided to go with dual dw301 pumps in my setup since i'm running e85 and bosch does not promise more than 500 hours of life-time with 044 with e85.

though will be running out of capacity this season so either i'll go for the dual veyron pumps or 1 fuellabs big pump with a reservoir with 1 dw301 in the tank.
