Don’t know the part number, but there were 2 sizes of fuel caps; the D2 used the smaller one.. Don’t know why you couldn’t use the red grease, I’ve used the Chevron version in the past. My motto is any grease better than none! Rollers one should really use the 00 semi fluid grease however. Someone else can chime in if they think differently. JM
