Modern Vespa

Apparently not.

I bought and installed a filter like the one suggested and fuel flow went from "gushing" to merely "dripping".

Back to having crossed fingers.

Sorry to hear that dude, where did you place it?

*edit* and what kind did you buy? they have a directional arrow on them for fuel to flow in one direction only, you saw that aye?

did you try the flow test by switching it to reserve and notice any difference?

I bought the one in link above. Put it under the seat a few inches right after the petcock, hanging down. Directional arrow is correct. Tested it every possible way with a full tank of gas. Just drips.

I just tried this stuff for the first time this week. First I put in a little simple green and water and a short piece of chain and then did the "fuel tank rumba".

I rinsed and did this three times until everything came out clear. Then I used the Metal Rescue and kept turning every few hours for a couple of days, then rinsed rinsed rinsed.

I shook out as much water as possible and then rinsed with seafoam. I set it in the sun (SoFla's natural heat gun). Once dry I put in a few ounces of 2T oil and made sure everything was coated.

I did talk to the guy at FUEL TANK SERVICES http://www.fueltankservices.com/about.html He does a lot of vintage stuff and he really seems to know his stuff. He quoted me $300 for a scooter tank. I'll give him credit, he did suggest that it may be cheaper to buy a new one, if available.

For what it's worth my fuel filter is like the one you have only it sits under my carb box just before the fuel line enters the box. Was surprised to see it there.

I actually tried it there first. Same result. I moved it thinking it wound flow better hanging down. No difference. To restrictive for this bike.

Now I have no filter so pretty much back to normal except now, for whatever reason, I can't get it to start at all.
