Installed in 72 challenger with a couple of minor over thought out issues. I didn't use the vents, but did use the 70filler neck with venting. I did have a small leak at the supply fitting just make sure you tighten the NPT fittings. I confirmed the sending unit using a multimeter several times and works way better than the aftermarket stock units. Once all the details were worked out the tank performs flawless. I reccomend this unit, although I had the best solution for venting in the challenger. Tanks provide two 5/16 nipples which I could not find a place high to mount their safety valve. Once I decided to change the filler tube problem solved. I capped nipples with small sections of FI rated hose clamps, bolts and indian head shellac.

Oh yeah I would keep powder coat the unit looks awesome and pump is nice and quiet.
