For you people running about 500+ hp, what fuel sender did you guys use? You would have to upgrade from the stock fuel line, right? Still using the stock tank? How bout radiator? And electric fan? Just trying to get an idea of what Im going to be needing eventually.
im in the process of having a new stock tank sumped,running 1/2 line and using the drain as the return port. I put a northern radiator with push/pull fans
'68 CobraJet lines are 3/8". Do you have these, or 5/16" lines? If you are not open tracking (long intervals of WOT), then those (3/8" lines) may be all you need. Several companies sell 3/8" senders for stock tanks. NPD catalog, for example, has one,
they are a bit pricey, and you need to build something from radio shack parts to make it work with your stock gages, but fuel safe sells some sending units that drop in from the top, and don't have any moving parts.
I'm running the same thing but I ran a second stock line right beside the original for more volume if needed. I use a mech pump in the front for one 3/8 line and a electric pump at the back for the second 3/8 line. I don't run both at the same time but can if needed, but the electric is mainly for backup and it supplies fuel to the dry carb when I do change overs at the track.
