WE HAD A HORRIFYING EXPERIENCE DUE TO A MASSIVE FUEL LEAK ON JAN 12, 2018, LESS THAN THREE MONTHS AFTER SERVICE HAD BEEN HAD BEEN COMPLETED AT CUMMINS CROSSPOINT ON OCT 18, 2017. CUMMINS HAD REPLACED THE ENGINE HARNESS ON THE ISL-400 ENGINE OF OUR MONACO MOTORHOME AS A RESULT OF AN EARLIER FUEL LEAK THEY DISCOVERED IN MAY OF 2017. CUMMINS CROSSPOINT ASSURED US, AFTER WE ASKED AT LEAST THREE TIMES THAT ALL FUEL LEAKAGE ISSUES HAD BEEN CORRECTED. WE DO NOT KNOW IF THE FUEL LEAK ON JAN 12TH WAS THE RESULT OF IMPROPER INSPECTION OR POOR WORKMANSHIP BY CUMMINS CROSSPOINT, OR IF IT IS THE RESULT OF DESIGN FLAWS OR INITIAL MANUFACTURING ERROR; HOWEVER THERE APPEARS TO BE NO OTHER EXPLANATION. AS WE EVENTUALLY LEARNED, THE MASSIVE LEAK WAS A RESULT OF THE #5 FUEL LINE BECOMING TOTALLY DISCONNECTED AS WE DROVE. IT APPEARS THAT THIS LEAK OCCURRED OVER THE LAST MILE OR SO AS WE NOTICED THE ENGINE WAS NOT RUNNING CORRECTLY AND WE EXITED THE IINTERSTATE A SAT DISABLED WAITING FOR A TOW TRUCK THAT ARRIVED THAT EVENING. AS WE SAT WE SAID A PRAYER OF THANKS THAT WE'D NOT BEEN INJURED OR KILLED BY A FIRE THAT MIGHT HAVE OCCURRED. AT NO TIME DURING THE INCIDENT WAS THERE A DASH WARNING LIGHT TO INDICATE THAT ANYTHING WAS WRONG. CLEARLY CUMMINS CROSSPOINT FAILED ON THREE SERVICE OCCASIONS, TO PROPERLY IDENTIFY AND RECTIFY THE FUEL LEAK WHICH THEY KNEW EXISTED, SINCE THEY REPLACED WIRING WHICH THEY TOLD US HAD BEEN DAMAGED BY SAID FUEL LEAK. THIS IS A FAILURE WHICH NEVER SHOULD HAVE HAPPENED TO A CUMMINS ?MILLION MILE? ENGINE. COMPRESSION CONNECTORS SHOULD BE ENGINEERED SO AS NOT TO FALL APART BY THEMSELVES. AFTER THREE FAILURES OF THE CUMMINS ORGANIZATION TO RESOLVE THE ISSUE, WE HAD THE REPAIR DONE BY AN INDEPENDENT DIESEL ENGINE REPAIR SHOP. WHEREAS THE FUEL LEAK HAS BEEN REPAIRED THE ORIGINAL DESIGN FLAW IN THE CUMMINS ISL400 ENGINE REMAINS.
