Fuel injector hose leak on Monaco with Cummins engine

One of the worst things that can happen if you're driving down the road in a class A motorcoach is to smell diesel fuel. it's happened to us twice and both times a crack or hole appeared in the fuel injector hose and sprayed diesel fuel all over the engine. We recently pulled into an RV park in Hot Springs Arkansas smelled diesel fuel went to the back it was dripping all over the ground all over our tow car & the back of the rig. With the engine shut off I called Good Sam road service and they said they were had to call 911 and dispatch fire engines. I said no you don't need to do that everything is OK now. he said don't dare start the engine I asked for a mobile mechanic and they said there were none. they were going to tow the rig in. I said there's no way you could get a tow truck up here so I had to cancel the dispatch. The RV park was irritated that we were blocking the entrance and said why don't you just start it, run it over to your space and then worry about it. I said no it could cause a fire and I refused. I then opened the back of the engine compartment, had my wife start the engine for about 5 seconds and could see right away where the fuelspray was coming from. Then went to an O'reilly's auto parts matched up the 5/16th gate's hose 4219bf and I cut out the part that was cracked, went to home depot got a 5/16th double end barb hose splicer # bhb-201anlb. And 2 small hose clamps. It was a messy job but I cut out the bad part spliced the fuel hose and it's working fine now to allow us to get home. It's all a dangerous situation but we felt helpless and nobody would assist.
