V6 to V8 fuel line question
When swapping a MPFI V6 to a fuel injected V8, are there any necessary modifications to the fuel lines under the hood(bending, shortening, lenghthening, etc). I am wondering if the v6 and v8 lines are both located in the same place in the engine compartment.

I went from a v6 to an LT1 and had to make my own because of the quick disconnect fittings on the lt1 fuel rail. I think that the only thing you'll have to change is prolly get longer lines, if that.

check out www.performanceplumbing.com. They have adapters for the LT1 fuel rail and they also sell kits for whatever you need.

If you are going from the MPFI to a TPI setup, all you will need to get is the rubber lines that goto the TPI fuel rail. If you are going to an LT1 setup, you will need the quick disconnect fittings to fit the fuel rail.
