Fitech swap on my 1972 K20 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

coopdog · 01-30-2016, 08:56 PM

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.

coopdog · 01-30-2016, 08:59 PM

I figured I would show some pics of the current set up before the swap

coopdog · 01-30-2016, 09:03 PM

Currently I'm running a 750 double pump mechanical secoundary, dart aluminum heads , headers , flat top pistons , and a 274 comp cam

coopdog · 01-30-2016, 09:05 PM

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

coopdog · 01-30-2016, 09:08 PM

More pics

coopdog · 01-30-2016, 09:13 PM

This is the most up to date status, I'm currently waiting on the fuel command center to arrive from summit

LostMy65 · 02-06-2016, 12:50 AM

coopdog · 02-06-2016, 09:34 AM

coopdog · 02-06-2016, 09:37 AM

Inlet fuel filter

coopdog · 02-06-2016, 09:41 AM

Fuel command center

coopdog · 02-06-2016, 09:49 AM

Hopefully today after wireing we will fire the old girl up

LostMy65 · 02-06-2016, 04:53 PM

Cool.
Is your gas tank in the cab?
If so, where'd you run your vent line from the command center?

**steelhorse** · 02-10-2016, 12:49 PM

Have you noticed any better mileage?

I have not gone for a true road trip yet because of all the snow and salt we just got, but when the weather gets better I will let u know

**CUSTOM/10** · 02-12-2016, 11:21 AM

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"

coopdog · 02-12-2016, 05:53 PM

Well fellas I'm into this deep so I figured I would treat the old girl a new set of slanted top value covers

coopdog · 02-12-2016, 05:56 PM

, sorry about the dirty engine bay , Weeks been busy and neglected to give the old girl her weekly cleaning

Nitis · 02-13-2016, 01:52 AM

what did you do with your return vent line from the FCC?

**CUSTOM/10** · 02-13-2016, 09:23 AM

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 ?
