Hi
Hope this helps u, know there are far more knowledgeable members than myself
Must confess I would go up higher as length of the wire is also relevant, what size is the existing cable please as that can also give u a general idea

How to Select the Correct Size Automotive Wire
User Rating: 5 / 5 In order for your automotive electrical system to perform properly, your wire must be sized properly based on the amount of current (amperage) the wire must carry, and the length that the wire needs to be. For example, you want to add some flood lights to your vehicle. The...

Wowzers deep stuff.. I will measure existing..I will be honest its a smidgen fatter than the 8amp I have but about 1/3 smaller than the 20 amp I also have.... Problem is I have no idea how long the wire is from source... assume its pretty much a car length.... This spur off the main harness is less than a foot long so its only that bit I am replacing.Hi

Ur so welcome and indeed can be confusing at times, lol
Assume the fuel pump is on its own circuit, do u happen to know what size the fuse is please , as the fuse needs to be rated lower than the wire so that blows before the wire starts to melt
Another confusing factor I found is some wires thickness can change according to the type it is
Would assume 12 x amps would be fine but would rather that be confirmed by others
Just done this on there voltage drop calculator , hope it’s useful to u , ref connectors I like the ones that have solder inside of where u just heat them up with a flame or heat gun , will find the link for u
Found those solder heat shrink connectors

Thanks for the help.. I have a load of those connectors, luckily this one has a junction.
Thats the wire in question. I measured it about 2.6mm... I only have 2.1mm or 3.3 wire so will have to source some more I guess... Do you think that will be 2.8mm wire ?
The fuse is 20a so I suspect that would make sense 20 fuse on a cable suited for 25 amp. Assume the insulation will take this up to 2.7/8 it was.

As always ur so welcome
Indeed that 25 amp wire should be ok, alas the link has gone , must confess normally buy my bits from 12 volt planet , plus there very helpful if u wish to double check things before purchasing anything
Handy ur able to do it on a workbench and not under the landy, lol, for any extra wires or vulnerable ones so to speak ive put them in conduit as an extra precaution, can also get a Y conduit piece , conduit in split or not
Plse let us know how u get on

I like that, the main loom is 43 years old and very weakened so I may well do that as well, wire turns up tomorrow, just hope I can find the new eyes for it.
This is the location, its a pig to get to so glad it disconnects.
Many thks and indeed ideal for inside the engine bay or near fuel tanks etc, just that extra bit of protection , often buy electrical connectors in a kit off eBay etc
