Thats what all us square body boys do!

Yes, 87-91 blazer/burb tansk work perfect. They do have the internal pump and baffling. To work with the LS all you have to do is drop in an EP381 acdelco fuel pump (or equivelant) which is physically exactly the same as the 87-91 low pressure pumps, but is a high pressure unit. Its out of something like a 97 one ton chevy truck.

So thats it! 87-91 tank, EP381 pump, done!
