I did a dorman repair kit, but didn't have much luck with it sealing to the barb on the new side. This left me heading to the store for some injection hose and double clamps at both ends. Never had an issue.

While this all looks good and seems great, we definately are putting these splices right above exhaust. A moment ago in a thread Scotty was talking about 120F intake temps. Engine bay temps get very hot and definately right above exhaust. I do the super deluxe braided lines with all parts that will never give out. It's costly, but like you mention.. lighting a car on fire.... Another thing that can be done is to take fuel injection hose and go down by the firewall or just under the car and use double clamps and hose all the way to the rail. That hose is rated for the temp and pressure.
