This guy just went bad and it's not the stock fuel pump for the vehicle (Toyota Landcruiser w/a Chevy V8). It's an external fuel pump, 50+ psi.

I stopped by the chevy place and they really weren't much help so i thought i could tap the collective wisdom of a shart chevy forum. I'm not 100% sure the pump came from a chevy but it's my first thought.

 

You shouldn't really care about the same one as long as you know the spec's for that one.Any aftermarket pump with the same spec's would work.
