Successful?
Who hear has a working FCC on their hot rod? I personally don't use them and have heard of a lot of issues. Let us know how yours is working and what issues did you run into, if any.
I was building a EFI system innside a 1965 Corvette fuel injection so it should look stock, used the FCC and hidet it innside the front fender. After building a EFI from scratch the startup is alway a thrill, test drived the car and suddenly it dies. Then I discovered there was no fuel pressure. After disconnecting the feed hose and looket at the flow and it was OK, reconected and retryed, then the pressure was back and then runs OK for a short time, then the engine shuts off again after some struggle. so it was clear this was a fuel deliwery problem. Opened the FCC, could not se any problem exept the Holley style float hung wery close to the FCC tank wall. So after some investigating I discowered that the float was stuck closed more or less, this restricted the fuel in to the FCC and after some driving with load the FCC got emty off fuel. I took the float off and did some adjustment to the metall part off the float to get it away from the tank wall and adjusted the float level. After this mod the car has been running all season with no problems.

I'm running the FCC. So far no problems (knock on wood). Mine is mounted far away from the engine and I made a vented heat shield to help keep heat down while still allowing air flow. Is it better? Don't know. Will it fail this summer in NC heat? Don't know. I had purchased it before reading all the negative comments. Talked to the sales guy at Summit and he said they sell a ton with very few problems/returns. Could have been a complete line of bull. I guess time will tell.

I put the FCC into my car (1965 Mustang "298" its .060 over-bored) and had the issue of it simply stopping and not starting a lot. I wanted the FCC because it only needs high pressure fuel line from the FCC to the FITech unit and a vent back to the tank (I used 3/8" aluminum tubing for that). My solution was simply to remove the float entirely. Now it is a self filling surge tank which recirculates the gas through the "vent" line back to tank. I get the advantages of having only a short section of high pressure line, the original fuel pump is never constrained it just always pumps low pressure fuel to the FCC with no float to dead head it, and recirculating fuel. Haven't has a single issue since removing the float. 🙂
This is good stuff. Thanks for the replies. I know a lot of people have issues with the FCC. I personally will not use one. I prefer an in-tank when possible. But, others look at it different. As long as it works for them....
Need some brainstorming on setting up my fcc. A little background- this is for an antique touring car with original fuel tank, no option for in tank pump. Engine is a mild cam, hei distributor, sbc. Fcc is mounted in front of the radiator protected by the spreader bar. The car is used for weddings, funerals,(yes), pparades, and crawling around fairgrounds at things like Back to the 50's. The MAIN consideration here is my system has to be 100% reliable. I can not risk spoiling someone's wedding day!

Sorry, caption for photo disappeared. This is the original fuel tank with 1/4 fittings for supply and return. Mounted at rear with low pressure pump nearby.
Unfortunately the most reliable is an in-tank. My second choice is a frame mount with a return style fuel filter. This saves the need of a return line from engine. Frame mounts are louder, but you can control the pump with Fitech. Lower the Fuel Pump PWM and it gets quieter and will lengthen the life of the pump.
You want to have a fuel pressure gauge either mounted to the unit or inside the cab. Lower the PWM until PSI drops below 58psi. Add a little to make sure the pump keeps consistent 58 psi. Pump will be fairly quiet then.
As for the return fuel filter, we were just talking about this. Here is the post with the information and part number. One guy posted a picture so you can see how it is installed. Get bck to us if you have anymore questions.
After learning about this return filter, I have no need for a FCC. To many problems, to bulky and to complicated...
Hi Austin - If I grasp this right I can use an inline Bosch 044 or Walboro 255 with the LS filter/regular and dispense completely with all the faults and foibles with the FiTech FCC unit? Thanks!
