What fuel line are you using? i know you said it was braided but do you have a source and part number? i shop almost exclusively at JEGS for the simple reason they have free shipping and are usually a buck or two less than summit.

What fuel tank switching unit (under cab) are you using? source?

I am installing all this in a pre-FI truck so i gotta make harnesses from the sending units to power source. I am hunting up detailed info on the HOT WIRE 'kit'. this looks like no fun at all!

I am planning to use the corvette filter/regulator on my swap for simplicity reasons. I am planning (if it will actually work) to use aftermarket fuel rails so i can have a single fuel line from the reg to the rail to keep things less clustered. but i dunno yet if the aftermarket fuel rails are compatible with the truck intake manifolds. I think the aluminum intakes manifolds sure look cool, but my wallet doesnt think than the expense of the intake manifold for the use of cheap fuel rails is worth it.

I got my hose and fittings from Jegs. I used their house brand braided hose and AN fittings. All -6 stuff.

My went into a pre-FI truck too, but only with a single tank. Can't help you there...As for the wiring, I used the stock wire for the Fuel Level gauge that ran down to the tank. I ran the fuel pump power wire from a relay on the fender well and followed the sender wire from the fuse block plug on the firewall down to the tank/sender. Simple.

Hope that helps. My son just swapped pumps to a Walbro 400, did not have to change anything except the base that supports the pump. Had to cut that off and use a hose clamp to secure it to the hanger rod. Getting ready for Turbo upgrade.
