has anyone had any experience the F. I .tech fuel injection systems,and the fuel command center? I see this brand advertised more than any. thanks.

The search function in the banner is the best resource in this forum. Type in Fitech, hit the 67-72chevytrucks.com button and then the google button. You will find lots of great threads on this forum discussing it.

thanks, I'll get on it.

I’ve had a FiTech system and the first generation FCC on my bone stock 350 in my 72, for about 2 years now.Works great, not exactly plug and play but even a novice can figure it out. Cold starts are incredible and drivability is remarkable.

holley sniper is an alternative. Bigger name, possibly better support vs FI tech. I have the Holley sniper. No complaints.

[scampr]

Did they effect the millage much or stayed the same?

[Ekliptix]

Didn't appear to change mine much (402). That's just from my impression. I didn't do a good job of before and after for mileage documenting.

Any one know of a fuel injection system that will fit in the stock (in cab) tank?

[jimijam00]

Any of them will since you don't need to go do anything with the tank at all if you don't want to. There are several different "kits" to get fuel.

I have friend who worked in a "shop" who installed a couple early fitech FI kits, said both were problematic. No idea of the "shops" skills or problem shooting techniques so took that info with a grain of salt, however as support of what Ekliptix indicated, typically small companies don't have the engineering or customer service horsepower to support their products completely.

I do have personal experience with installation of a Holley Sniper EFI kit and have to say it was absolutely the best thing I have done to my truck from a drivability standpoint. Had numerous carbs on the truck with very poor results. The start and idle quality of the sniper is great, mileage went up from 13-14mpg to 18mpg as checked on a 2k+ mile trip. Another sniper is on my list of items for my 67 Nova build.

Whichever system you choose, do a bunch of research, have a plan, take your time, read the instructions about 20 times, and don't short cut steps or it'll likely cause you grief.

question on the fuel pump. I know electric fp like to be gravity fed. If using the in-cab tank will it supply fuel OK to the pump even if you run out of gas and refill the tank?

[Bigdav160]

I once had a '72 that I installed a TPI engine. I used an external pump under the cab.

I never had a problem with the pump siphoning fuel from the tank but it would pick up air and howl anytime under 1/4 tank of fuel.

My tank is in my cab and I am running the FiTech system with a inline pump. I added a 3/8 supply line to my fuel sender, moved the stainer over to the new line and hooked the return up to the original 5/16 line. I tried using standard plumbing solder and couldn't get it to work so I used some Silvaloy brazing alloy that I normally use for HVAC. It has been working great since 2015.

I read several threads about issues with the first gen FCC. I would hope FiTech has worked out all the issues with the latest version. There customer service has been excellent for me. They have helped me over the phone & answered my emails. I broke the handheld programmer and they sent a new one free of charge.

I'm using the FiTech unit with a Edelbrock fuel sump fed by the mechanical fuel pump. It has been working great for me!

A Facet 60106 will supply 4-7 PSI and lift 36", so they claim. I just ordered one. I had bought what I was led to believe a Carter P4070 but there are no markings except a different number on the box which took me to a copy-cat MIC pump. I'm sending it back. I'm going to use an Edelbrock sump to supply the higher pressure to the TBI.

I modified a Tanks Inc GPA-2 pump to use in my factory in-cab tank to fuel my LS swap. Not finished yet, so don't know how well it is going to work. You have to cut a hole in the tank next to the original sending unit/pick-up.
