Fitech swap on my 1972 K20
I have not done much to my K20 in a while, I had been researching fuel injection for a while and after my brother put a 6.0 LS in his 54 International, I knew it was time to bite the bullet and modernize my old carbureted small block.

Re: Fitech swap on my 1972 K20
Some pics of the new system I went with the tumbled finish in stead of the black, it's rated for up to 600 hp

Re: Fitech swap on my 1972 K20
Cool.
Is your gas tank in the cab? If so, where'd you run your vent line from the command center?

Re: Fitech swap on my 1972 K20
Hmmmmm......
![]() ![]() I just looked up that Fuel Command Center and that is a slick set-up. You leave your exsisting low PSI pump in place and feed the FCC from it. It's a sump with a high PSI EFI pump inside, and you feed the feul injection with that. Nice & easy !!!! Thanks, now I have to spend more money !!!! "LOL" Gary

Re: Fitech swap on my 1972 K20
Did you have to run a return fuel line back to the gas tank ?
Also what about venting, do you have a vented cap or a vent line of some sort ? Gary
