My 2001 bi-fuel 15 passenger van is having an issue with stalling while running on CNG and then switching to gasoline when restarted. I suspect it's time to replace the HPR filter. The kit, part number 52368706, is available from gmpartsdirect.com for about $20, but I can't find information on the procedure. Supposedly there's a post somewhere on the forum, but I can't find it. I'd appreciate any help.
Thanks
