So I thought I would be slick and use only enough wire for what I needed when I wired my EFI in tank fuel pump. Who needs the excess wire right?

Then I Used heat shrink, all is good. However, I DID NOT use gasoline resistant heat shrink. At the time I didn’t know that was a thing.

Question:
Instead on buying a new pump hanger Would it be alright if I add a section of wire using another set of crimps and the proper heat shrink?

That would be a total of 4 crimps, not the original 2.
