ls swap fuel pump ?

when I attempt the ls 5.3 swap I plan on using a external mount fuel pump, so if it does work how big of a pump do I need, also I already have a 87 tbi fuel tank so what sender would I need

If you already have an 87 tbi tank, get an 87 tbi sender, and get an "in tank" walbro pump and be done with it. Will fit right in the sender, hook up your wires and hoses, burn rubber.
