Extending Fuel Pump Wiring... splicing?

If someone were to cut the wiring a little short on a fuel pump replacement, whats the proper way to add wiring to make up this slack?

I am wondering:

Do you have to go all the way back to the fuse box? or can you mearly splice a length close to the pump?

Also the pump takes 18awg and 14awg stranded. What is the proper type (temp rating etc) of wire to use for this application?

Of course it would all be taped and inside a plastic conduit tube. The wire is not inside the tank, rather on top of the tank. I assume that makes a difference when choose a type of wire?

I would repair with the same size wire but use heat shrink tubes over the connections rather than tape. No need for rewire. Soldering the connections is also a plus

Larry has given you good information. Soldering is always a preferred method of splicing under a vehicle and the shrink tube makes an excellent covering. You can also go one step further and get the heat shrink tubing with glue inside for an extremely weatherproof splice.
