when is this necessary ?

i have a wabro 255 intake pump replacement, and plain on running 15-17psi or ~300whp.

if i do need to do this. do i just replace the wire from the pump to the relay under the dash. or do i need a full rewire from battery to new relay to pump. ?

you just use youor stock harness it works fine

 

what he said.
it just drop right in!

 

i already have the pump in place and it's working great.

im just worried about not having enough voltage for my application

no one else has had this issue.

you will not have any issues with that setup guanranteed tons of people have used the pump on stock wriing for the longest time. If you were going to say run an external pump then i would wire in new realy new power source and everything

 

cool thanks for the info

i guess i was trying to be better safe then sorry , but if it's not needed >>

thanks again

Just as everyone has said you'll be fine just using the stock wiring...

 

I use two power sources for my pumpm that I toggle between, one is stock ugraded gauge primary wire to the pump relay, the second I run direct off the alternator when I need more volts, I get an additional 1.5 volts this way, at around 13.5-14.5 volts my pump actually runs cooler. I wire off the alternator because honda alternators are internally regulated meaning they only send 12 / 12.5 volts to the battery so i get the voltage before it is dropped down..

 

thanks for the info
