The point I am making is why use massive cable that carries vastly more current and costs vastly more than is needed, when what I have suggested is more than adequate.
Yes the cable I have suggested is more than capable of torching your car, but as it can carry a lot less current if it does say rub through somewhere it is less likely to, personally I favour thinwall, as it is MUCH more resistant to abrasion or even type 44 cable which is aero industry stuff, same as we use on the ecu looms, and the new fan looms/fuel pump looms.
The stuff from maplins is fine at 30A.
The diagram shows the original fuel pump feed AFTER passing through switch which is always the best bet, not needed with aftermarket ecu as these cut the fuel circuit as soon as cps signal(engine) stops anyway.
