Superduty 5.4 2nd battery cont.

3- mount new battery box to existing holes

4- Remove air cleaner hose fron rear to injector

5- Cut origional air-cleaner mount using about a 2" wide piece with fe-male receptrors and bolt to battery box bottom. Make sure air cleaner fits between battery box and radiator.

6-Make a strap mount for front snorkel, where air cleaner goes through core support, 90 degree bent piece of 3/4 wide x about 6" long to origional bolt hole and a hose clamp.

7-Cut air cleaner rear hose about 3" will do

8-Make splice tube for rear air cleaner hose a muffler shop expaneded 3" stainless to fit nicely, about 2 1/2" long and 2 hose clamps, install

8- Go to local auto supply house make cables and install

9- I used a slightly smaller battery to gain air cleaner clearence and a GM battery hold down

10-The Auto Electric store told me they could make my alternator put out about 180 amps from 130 amps using existing alt.

11- Happy Plowing

Skip the extra battery. Just go with the 180 amp full output alt. and the larger cable from the alt to the battery.

I like the Idea for the extra battery location mounting but have had good luck with the bigger alt on all of the Super Duty's
