Michael, I looked into that when I was contemplating a Volvo 3L purchase. The triple set-up was used mostly for Volvo Marine applications (Volvo Penta). You might contact www.ipdusa.com and see what they might have available or know of. Some of the UK folks have triple set-ups. Still rare as hen's teeth ! There's always Ebay... or EbayUK. Don
