I bought a tank with an inline pump from boardmember fuelcellguy.

I bought my ducting for the intake from jagsthatrun.com.
I reused the stock harness. I bought the factory Helm manual and it was a HUGE help. I elimated what I didn't need from the factory harness. I highly recommend using the factory harness, going through it to eleminate what I didn't need taught me a TON about how the system worked. It really did help with my swap.

I forgot to add, but you probably already know this. You will need to modify the middle four bolts on your intake to work with your older style heads. It's not a major mod, just something to keep in mind.

It depends on how big of injectors you are going to run 90 psi will work great for a 305 or a stock 350. You dont have to modify the center bolts if you get an intake off of a 85 or 86 tuned port
