Modern Vespa

So I've put a little over 300 miles on this scooter since I got it a couple weeks ago and over the weekend, I took it on a long ride in slightly warmer weather and it did not want to start again after stopping for a few minutes. Fuel pump relay clicked, but the pump didn't make a sound. After about 20-30 minutes of cooling off, it fired right up. All symptoms line up with the fuel pump recall on these bikes from 2015. Well, after doing some calling around to dealers, it turns out that the fuel pump on mine was replaced in 2011 under warranty. So as far as Piaggio is concerned, the recall has been completed. But in my mind, if they replaced it in 2011, wouldn't it most likely have been with the same defective part number? Has anyone else had a similar issue? Should I just suck it up and replace it myself or try to get a more favorable response from Piaggio? They don't answer their customer service line and haven't responded to my email inquiry. It is a 14 year old bike, so it's possible the pump is just wearing out, but it's also only got 6k miles on it.

Meh... I decided screw it. There's a couple things I wanted to order anyway, so I just added a new fuel pump and gasket to my cart. Robot's video on changing out the pump is very helpful. It's probably not a bad idea to check the valves and that's 2/3 of the work already done if I do both at the same time.

There are three part numbers of fuel pumps that fit the GTS. If you order the latest part number, you will get the upgraded part. Piaggio still has the original pump in their inventory too, so make sure you order the right one for your scooter.

Thanks. I hadn't considered that. I believe it's the newest one, but I will double check.

I think that maybe the scooter I looked at and decided not to buy. I looked in either this forum or another and read where the owner posted about fuel pump issues but never posted they had it fixed. I hope you get it fixed.

Thanks. I should have all the parts next week. As long as I can find some time to work on it, it should be fixed soon. Luckily it still runs and doesn't have any issues on short rides.

The new fuel pumps come with the gasket included, so you don't have to purchase one separately. It's a big O-ring that's about $15 or so if you have to buy it separately, and absolutely worth replacing.

Oh. None of the places I found it for sale mentioned if it was included or not and the product photos don't show the gasket on there. So I just assumed it wouldn't come with one. At least it was cheap if it turns out I don't need it.

Piaggio has three different fuel pump part numbers that fit the GTS, are not the same ones that fit the HPE, are still in production and range in price from $180-$230. It's confusing as heck, there's a lot of year and model overlap and the newer pumps are cheaper than the old part numbers, and include the gasket. Go figure.
Consider yourself lucky that it's not a GTS 250. Those fuel pumps are almost $300 now, and some of them need to be replaced even though the recall was already done. Five years ago, they were well under $200.
A lot of the Beverly and MP3 pumps are crazy expensive too.

It is possible to just buy suitable motors from aliexpress et al, which is a far cheaper way of doing it, but you'd need to be happy to do a bit of inventive tweaking...

I considered something like that, but with the age of the current parts and the relative simplicity of just dropping in the whole new assembly, I figured it would be better to go that route.
