Just finished The install of an HFI on my pickup. Just wanted to give a little rundown of it if anybody is on the fence about it. '73 1110 with 304 and BW automatic, I used a '91 blazer 31 gallon tank with the in tank TBI pump; tank, pump, sending unit and straps under $200 from rock auto. I used a fuel gauge interface module from speedway motors to make the GM sending unit work correctly with the original IH fuel gauge. The Hamilton system is a very complete and well thought out system, instructions are very thorough as well. Followed the directions and completed all the prestart checks and when I went for the first start it scared the crap out of me when it started almost immediately!! From there I completed the initial timing check, iac setup, and finally the tps setup. Haven't had a chance to log any drive time yet but the immediate starts are impressive already, can't wait to get some seat time and log some data. Thanks Bill for all the hard work and time you've put into these systems.
