Received a call today that Kissell Motorsports put a new fuel pump in my scooter. While the pressure test was ok it was making unusual noises. And on the road it would intermittently fail and no longer make any noise. The technician showed me the old one and it looked pretty grimy. A new fuel pump seems like the best course of action.
The Vespa GTS 250 fuel pump is a known issue and was subject to a recall for a great many scooters. Unfortunately mine was not among them.
I had the scooter die three times on the road due to this problem. They all had the following in common that seemed consistent with fuel pump failure:
- Fuel pump motor did not spin — the usual pressurization when the ignition is switched on was absent.
- The fuel level was low each time the pump failed — from what I’ve read the pumps overheat and the impeller binds causing the motor to quit spinning. After the engine cools the pump began working again but it would only be a matter of time before it would not come back to life.
So the scooter is close to being back on the road. I dropped off my Heidenau K66 LT Snow Tex tires to be mounted which should have me all ready for the rest of the winter riding season. For anyone considering year round riding I can’t stress how nice these tires are for rain, snow, gravel, slush, and plain dry frozen roads. Noticeably better traction in all cases. The only negative is that you lose a bit of responsiveness — the flickable nature of the Vespa is impaired a bit. You get used to it quickly though.
With the fuel pump replaced I’m good for another 25,000 miles or so…
