Anyone have ideas on a source for a inexpensive 12v water pump for the d.i.y. hydronic heater I'm designing for my box truck?
Low current draw is the biggest priority- seems like 1 gpm would be enough.
What's going to happen if I run water/antifreeze through a fuel pump?
My truck has on-board compressed air, so if I could figure out how to circulate water in a closed circut using compressed air, that would be better yet.
