Small diameter modern rubber hose replaces the large diameter-small bore original hose that feeds the oil gauge and allows for engine movement. See also CAM4202 and 21A0804 metal pressure pipes. Also see C-AHT9 for race-quality metal braided hose kit which can be used in lieu of the the original arrangement.
Hose clamps are not included with the purchase of the hose. You will need to order two (2) AAU1818 clamps, since the original ones are too large to fit this hose.
