electric fuel pump question

[Waldoe]

My truck has a carter p4070 electric fuel pump on it. It is a bit loud before start-up, makes a squealing noise when I shut the truck off. The noise does not bother me, as I only hear it before i start and after I shut it off. I think the rubber bushing are probably wore. My question is that I am thinking of getting a spare, for when it is needed. Any opinions on the brand? Should I just stay with the carter? Thanks

I'd go ahead and change it, my efi pump was squeeling just like that, did not think much of it. But after my can install I kept having a lean condition . Pulled my hair out with mass air meter, intake routing, computer 're tune. I had good psi at idle. Finally changed the pump and it solved it. If I was a betting man yours is falling off under a load as well .
