;) These figures would be suffice to cover the max length used in most vehicles.It stands to reason that the longer the wire more volts are reqd to force the reqrd Amps thru.

That's not how electricity works though.

If there is too much resistance in the wire the current will go up, which causes the wire to heat up, which causes increased resistance, which causes the current to rise, which causes more heat.....

Including the wire length in the spec "max current capabilities" of wire gauge is very important. There are some wire lengths in vehicles that are only a few inches, while others are several feet long, which can change the required wire gauge drastically.

mate your car has a aftermarket loom autronic from memory and they have a 15a fuse for the fuel pump for a 044 style pump .but if you have a lift pump as well you should run a separate relay and fuse or you may have a problem
