Not everybody runs thicker wiring to it, but if you do you can use the same relay.

I went the 2nd route... 1 relay for each pump..... (I have 2) 10 gauge....

thanks fot the pics,


do u mean the stock relay?

Re: need help on wiring walbro fuel bump.
 

Couldn't you just wire it the way the stock one was??? Maybe run thicker wires but not sure it is mandatory.

Re: need help on wiring walbro fuel bump.
 

NO, that defeats the purpose... Run the Power wire to the battery (or the alt post), run 10 gauge - (dont forget a fuse) to the relay you ARE adding... and use the stock fuel wire (coming form the stock relay) to switch the added relay, and in effect turn on your pump (S)

cool.... that way it wont draw alot from the stock right?

Re: need help on wiring walbro fuel bump.
 

The curremnt drawn will be from either the alt post, or battery DIRECTLY... The stock lead will simply switch the new relay and allow the current to the pump (s)

so thanks.
so will it be ok just use the stock wire to trigger the relay and mount the relay near the pump and then run thicker pos & ground wires?


ps
what relay amptitude will i need?
