Scott, The 4426 that's on my RR had a pink paint stripe across the E8 4426 on the base when I bought the car. The car had been sitting for 20+ years and I needed to go throught the fuel system, when I soaked the carb I lost the stripe. Does the stripe have any meaning? Wish I had taken a pic before I soaked it, but didn't. Sorry for going off the topic here, but just wanted to know.
