Where can I find an 1987 TBI Fuel tank with electric fuel pump sold as a kit ready to install for my 76 K10 4x4 wanting to keep it EFI ..Do we have a vendor on here that sells them?...Any advice will be greatly appreciated

The tbi pump will not put out enough pressure/flow for an ls,as to your question,i think holley has tanks and/or pumps that will work.

If you want to spend hundreds of dollars, go buy a "purpose built" tank from one of the aftermarket suppliers. If you don't want to spend that kind of money, then just buy the proper pump and replace your TBI pump. It fits right in the sender unit with very little modification.

Well, Holley sells a sweet little fuel tank for your truck for like $800. It gives you basically a stock tank with a fuel pump module and a separate fuel level sensor. Or you could buy a stock '87 tank for about $160, fuel pump module/sender for about $80, and an EP381 fuel pump for about $90. That is $330. You will have to address the different size fuel fill on the '87 tank to your side of bed fill, but that shouldn't be hard. You can also use the Corvette Filter/Regulator if you have a returnless system on your LS.
