Holley Sniper Stealth EFI - Part 8 (Fuel Tank Preparation)

Occasionally, over the last couple of weeks, I've gone to the garage after work to get the fuel tank ready for installation.  As stated before, I purchased a Tanks kit (TNK-MU-HT-KIT) which includes a TNK-GPA-4 fuel pump, TANK-TAN-ORG sending unit, and a few other items.  

The adjustment process starts with measuring the depth of the tank the fuel sock on the pump is 1/8" off the bottom of the tank.  The return line is about an inch of the bottom of the tank.  


After some cutting of the supplied tubing, a few hose clamps, and use of included zip ties, the correct length fuel pump is ready to be installed.  It comes with a cork gasket that I coated in Permatex 85420.  


The process for the sending unit isn't much different.  I somehow neglected to take a picture of the final adjusted piece.  Essentially, the long metal bracket that has the rheostat at the bottom is cut to fit the tank.  The float arm slides into it and is cut off so that the float a full height is 1/8" below the top of the tank.  This piece came with a rubber and a cork gasket so I just used the rubber one as I expected it would seal better.


Lastly, there is the tank side of the filler neck that has a cork gasket.  I coated it with the Permatex too and bolted it into place.  Everything with the tank is now ready to be installed.  I'll just need to do some work with the truck floor before I install it.


Additionally, I took the old fuel filler neck, used paint stripper to remove all the old crusty paint off of it, and painted it matte black using some Krylon Fusion paint (#2754).
