    im converting my '88 k5 from a TBI 350, to a GM 454 HO with a carb.

    since there only needs to be a feed line, what can i do about the sending unit, being that the TBI unit has like 3 or 4 lines.

    You can use the same sending unit over but you will need to remove the fuel pump and make some kind of hose to take its place and then just plug the unused return line fitting.

    If you use the stock in tank pump you must get a regulator with a return line. If you just use a basic fuel pressure regulator without a return it wil ruin the pump in a short time. The pump has to circulate fuel to keep it cool. It will burn out in a short time if you dead head it. You can get regulators with a return from Summit and Jegs
