Once you have checked for obstacles under the vehicle & determined the correct hole
positions, drill 3/8” holes for each bolt & hold down rod. Use a drill bit depth stop or shield
if needed to prevent going through too far and damaging vehicle components.
3.
Thread 3/8” jam nut
⑥
onto hold-down rod
⑤
to proper depth
to go through van floor or wheel well; about 1-3 inches.
4.
Thread 3/8” coupler
④
onto the top of the hold-down rod. Place
3/8” tap bolt
③
through hole in hold down bracket
②
and
thread bolt into coupler.
5.
Place 3/8” fender washer
⑦
on rod & push rod through hole.
Hook the bracket over the edge of the tank and tighten the tap
bolt and move the jam nut as needed to adjust the height of the
hold-down assembly. Leave extra threads open between the tap
bolt and coupler and coupler and rod for later adjustments if
needed.
Adjust rod height to secure the bracket to the tank
such the bracket and tank will not move, but not too tight.
Over-tightening the hold down rod may damage the tank.
(If you had to move front hold down over to shelf area to avoid
obstacles you will need to shorten hold-down rod.)
