Alex,
Most of the Buick Skyhawks and Monzas
I've seen don't have a mechanical fuel pump. The
electric one in the tank will provide 4.5 psi. If you have
one on your 3.8 It would most likely provide no more
that 6 psi in stock trim. Good Luck.

Thank you John, I'll put on it a edelbrock performance combo intake, cam, holley 600 cfm. I think a 6 to 8 psi will work.
Thank you again
Alex

Alex, don't run any more than 6 psi at the
carb,
Qjets can take more but you have to be carefull with
holleys, to much pressure on the needle and seat! 6psi
will do the trick if you need more fuel run a 3/8"
front to back, the way the factory sized the fuel lines
was 5/16" from the tank to the firewall and then 3/8"
to the carb, at least that's the way mine was and
still is.... for now.
Ian.
