All the stock ones have a leak....The way they were mounted left lots of places for dirt to build up and in 30 some years ..Bingo !! lots of rust and then leaks....I looked around for a stock replacement but it was too much $$ or not avable,I don't remember ,long tome back ...anyway ,I installed a 10 gallon boat gas tank on my 1978 flat bed.I use a rubber mallot to see how full it is....I have friends that say "Get rid of the old thing" I say No way !!! Good luck, Todd
