Fuel Pump/Sending Unit Question

[Groyd]

I have a '51 on a '97 s-10 frame. I've got a 5.3 from a '04 GMC Sierra.

Question : I picked up a different fuel pump to get the right pressure, but the sending unit for '96 and up s-10's doesn't allow you to change the pump . You have to change out the entire sending unit. Would I be better off getting a 95 or older sending unit and changing the pump?

Question : I know a lot of people with these trucks do rear mounted tanks. What would be the best fit in the s10 frame? Has anyone got any pics of something different in the s10 frame? Is the blazer tank the best bet? I just don't want it hanging out under the truck looking like trash.

Thanks,

MG
