Will a pump and sender from a 1987 gn fit in a 1976 skyhawk fuel tank ?

Are you looking for a direct replacement? The GN is fuel injected so the pump is a much higher pressure than a carb would use. The sender unit looks nothing like a stock sender and the sender needs to match the size (depth) of the tank. What exactly are your plans? Here's a pic of the GN sender, obviously looks a lot different than a stock sender. It might fit the hole in the tank if that is what you were wondering, you have to try.

I can't tell you about the GN pump, but I successfully mounted a V6 Camaro/Fiero FI pump to the sender on the Cosworth I had. I wrote an article for the Cosworth Vega Owners Association Magazine covering it that I could send you.

Yes. I have a gn pump in my 77. Problem is no baffling in the tank so it needs to be kept above half full.

I think FItech recommends a Walbro 255 or equivalent. GN pump would probably be adequate. I have to install a Fitech system in a 67 Nova this week. System looks excellent for the price(less than half of what FAST or Holley want for the same thing).

and 3 more Saturn "parts cars"
Note- the very act of listing all of these has made me realize I have some kind of problem.....

what, if anything, does everyone use to baffle the fuel tank, as sloshing fuel will allow the pump to suck air.
