easy fella bit more work required if u want to follow the original wiring around the fuel tank like i have etc need a fused live straight from battery to a relay (40 amp one ok)then use the feed from your cut off switch to your pump(if u want the cut off switch to be in the circuit still)for the switching circuit of the relay,use your original pump earth to earth out the switching circuit,then a fresh live down from your new relay to pump and new earth from pump to body

or look in technical archives pics there etc

click here this is how i done mine

should be fine mate, ive topped 160 a few times and hit the limiter in 4th at about 140 a few times and exhaust temps havnt gone above 700 c. at the end of the day its a 12 v pump and youve got 13 so cant see any problem personally
