On all the filler necks I've seen on gas tanks, the necks are always soldered on. Can someone tell me why that is?
I even read a tech article in one of my Truck'in magazines, where they drained and flushed a gas tank, drilled two large holes in it and sandblasted it all out, before coating the inside with a gas tank liner and welding the holes shut, and then even after they did all that and used a penlight to check everything before welding up the two holes, they soldered the neck on.
Is there some reason why the neck shouldn't be welded on? Is it fear of obstructing the inside of the neck if the penetration becomes too deep?
