Holley Sniper Stealth EFI - Part 2 (Parts Arrive)

The Holley Sniper Stealth EFI system arrived in the mail today.  I quickly opened it and spread out all the items that came as part of the kit.  I'll need much more to make this work but everything I expected to receive was included in the box.




I placed the throttle body on the intake and it seemed slightly taller.  With some quick measuring, I found the Sniper unit was a 1/4" taller than the Street Avenger carb.  I placed my air cleaner on and found that it now makes contact with the hood.  I've been using a 1/2" phenolic spacer which I can remove.  I added the spacer to address issues with vapor lock.  Since the Sniper doesn't have bowls to store fuel in, the spacer will have much less benefit.

I also noticed that due to the design of the top of the Sniper, the threaded hole for the air cleaner stud is lower.  As a result, my former air cleaner stud is too small.  I need one that has a 1/4"-20 thread pitch and that is hopefully around 3.5" long.  I'll add that to the list of things to purchase.

Before the Holley Stealth kit arrived, I decided to go ahead and purchase the gas tank I'll use with the Stealth EFI system.  I purchased a Tanks brand kit (TNK-MU-HT-KIT) which includes everything that I will need associated with the fuel tank.  The tank is a 16 gallon tank with internal baffles and is powder coated silver (TNK-MU-HT-KIT).  The tank came with the pump (TNK-GPA-4) and a Ford style sending unit (TNK-TAN-ORG).  Despite ordering the tank several days after the Stealth System, it arrived first.
