    Based on the fact that two of the top three searches regarding the FCC have to do with problems you aren't the first one.

    well the fcc didn't work out and summit was cool enough to return it since fitech couldn't come up with a fix. i tried the corvette filter and external pump but the filter/regulator isn't keeping the pressure where i need it and when i was around an 1/8 tank i am getting a surge. when i fill it the surge goes away so i'm writing that off to the carb tank pickup creating a siphon effect and introducing air into the fuel. so now i'm going the '80's tank/pickup and higher pressure pump route. this means i'll have to add the return from the t-body. i've removed the steel lines and ran nylon for the feed so i'll run the same back for the return. i went nylon because of the salt used during the winters, everything rusts here.

    I used aluminum from summit. It worked out really well.

    unfortunately even aluminum gets beat up by the salt.

    I can attest. I unwittingly bought a pair of aluminum valve covers on eBay from someone on the east coast. I was amazed at the corrosion, some places it had almost eaten all the way thru.

    I am doing the fi tech conversion this weekend or next, I am using the rubber hose / in tank pump method. I've heard good things about going this way and have seen it first hand on a couple ofvthese blazers

    I've been thinking about the FiTech for my 66 and it would be really nice if the FCC would work but it seams like so far that may not be something to count on. Luckily LMC does do an FI in-cab tank so I could do an external pump. One thing the in-cab tank is well suited for is the external pump since it's not hard to get the pump well below the tank.

    fcc has been a crap shoot, they say it overheats and thats no good
    i have read where they run a return and it does better but the floats in em stick and the pump fails. but there are those that have no issue with em.
    I just think in tank will do better in the long run. just my 2 cents

    I would steer clear of the FCC. Also keep in mind the pick up in the tank. I have the holley external pump now and the oe tank for a carb. Below a 1/4 tank I am getting a surge due to air from the the suction. I'm switching to the in tank set up now.

    Have you checked out this one recommended by users on one of the fitech user groups from FB:
    http://www.robbmcperformance.com/products/powersurge.html

    Might want to look into it as it looks affordable and from what users have said, is reliable.

    Yes actually I did see a lot if people talking about it, I think on a Chevelle site. Thanks for reminding me. Had been thinking about keeping the carb but then I was thinking FI would make mountain road trips easier.

    Well I'm finally done with the FI conversion. I installed a later model tank, intake pump and pulled the steel lines off and used nylon to deal with the rust issue up here. It runs great and no more low fuel level issues. While I was at it I pressure washed and sprayed some under coating to try and save the frame as long as I can.
