Fuel tank for My Imp

My Imp has a Holley external fuel pump, no mechanical pump, & I would like to convert to either straight mechanical, or, electrical & mechanical. Will the fuel tank listed on eBay for Mirada's work on my Imp? The Imp tank is 17 gal, the Mirada's is twenty. I know the sending unit is different due to the electric pump. What is the best way to do this? If I can use the Mirada tank, will I be able to use the Imp sending unit w/integral electric pump? Isn't the trip comp. tied into the sending unit (I'm being lazy here, I haven't dug into the fsm to find out) wiring & lines? Thank you, Larry
