As far as fuel system goes. You can use a fuel Chevy LS filter/regulator combination that is available for 33.00 from Amazon, plus a electric fuel pump from DIY for 110.00. You'll need to add some lines and other items. Personally I am going to buy a brand new tank. The point I'm making is that you can do this for way less than $800.00. Of course you'll need to do some fabrication including the addition of some return lines.
