Mabis bulb n valve
I purchased the bulb & valve to replace similar bulb pump in my van's driver seat and other captains seats lumbar back support. Unfortunately after installation the lumbar air bag inside is not firming up. The bulb n valve connects to the rubber tube but the lumbar bag is not firming up after pumping the bulb. The bulb may not be the right size for it or the air bag for the lumbar may have a hole. Either way, it's worth a try but just didn't work in my favor.
