Last week I had annual service at Spartan in Charlotte, Mi. which included fuel filter change. Service was completed Friday afternoon and we decided to stay there until Sunday when we could check in for Newmar service at the mothership.
So Sunday morning go to start engine and it immediately shutoff. Thinking it might be air in fuel system, cycled the key on for 10 seconds then off repeating this sequence 2-3 times and attempted to start with success. I then go visually to check filter only to find it leaking fuel. After shutting engine off I check for loose filter, nope it was tight. Called customer service, left message and got a return call about an hour later. While I was waiting I decided to change filter since I had a spare, well it takes a 25mm socket I didn’t have?. Off to Advance Auto parts and get required socket, success. This filter is in plastic housing and it is so tight that I am now concerned about the 25mm plastic nut I am cranking on. Spartan calls and says tech is on the, time for me to put my tools away.
Spartan recovers well installing new filter, after removing the old gasket they left in the filter housing, which caused the leaking filter.
Lesson learned be sure to have proper size socket if you carry a spare and remove the old gasket.
