Thanks for the heads up.
I was going to mount it today. I'll have to pull the battery anyway, since it went flat last night. Then the batt bracket. If I can get any down angle on the bottle, I'll do that. I do have a small-but-long funnel for the purpose already.
One concern is that this item will block access to the very tip of the fender bottom. Where slipped 1/2'' wrenches all go. Also, if left undisturbed, packrats can leave a nasty surprise from cholla and prickly pear thorns. I guess I can fish with a magnet-tipped tool picker.
Does the system suck coolant back into the radiator if it's low? Or is it simply to keep it from splashing out under the engine when it overheats?
