How hard is it to remove these for cleaning? Just remove the 2 bolts through em and they come off? Or when i take those 2 off is the whole 20 gal. tank gonna come crashing down? Reason i ask is, everytime a hose gets near these shields mud comes pouring out. I left a hose in one for 30 mins one time, guess what, MUD STILL COMES OUT. Worryin this might cause the tanks to rust or somethin. Any ideas? and is this a fairly simple thing. While im thinkin about the gas tanks, i have 2 20 gal, and a FI engine, do i have a fuel pump in each tank or just one somewhere in between? Like say my left pump died, could i change to my right tank and keep on driving, or would my truck be dead? Pumps arent goin bad or havin me worried or anything, just wondering.
