Quierototolive, do you find that with this 'behind the bumper' installation that the pump is adequately protected from the elements? It doesn't get wet from road slop, does it?
I also don't want to put the tank in the back of my hatchback, but there are few options (no space) for a complete 'under the hood' installation.
Is this working out okay for you?
Did you conisder and reject using the windshild washer fluid tank (1.0 gal) for your meth/water solution? If so, why?
Thanks for any input.................... Frank
