Review on LTWFITTING Brass Splicer Mender Fitting by Josh Chenier

I have a broken piece of plastic on the return injection hose. The dealer wanted $190 for a new one. I checked the Sprinter forums and this was a very common problem. A few people suggested attaching it with barbs. They fit perfectly and are strong enough to never break like plastic. The opening inside is large enough for proper fuel flow, which is important for the computer that monitors fuel flow through these lines.
