The "...space between the battery and fender..." Never heard of that. Do you zip tie it in or trust it won't wall out?I’ve always been a Fumoto user and have nothing but good stuff to say about them. However - I did opt for the Valvomax on my JLUR at the last oil change a couple of weeks ago.
I know the likelihood of hitting the valve while rock crawling is slim to none, but I felt that the Valvomax being stainless instead of brass would be more likely to survive a hit. Storing the hose is a non-issue for me. I just put it in a ziplock bag and drop it in the space between the battery and the fender. It won’t get lost, and it’ll always be with the vehicle if for some reason I should need it away from home.
