Sounds like there was an era when the tips and inlets didn't match. The steel bodies always came painted black, until they rust, of course. > 4 NOS > Yellow inlets, black body, yellow tips.

They'll last forever stored like that, as long as you keep them dry. > 4 questionable spares > Yellow inlets, black body, 3 of 4 have yellow tips that are hard to > remove and haven't pulled them off, 1 has a black tip that slides off > with some coaxing.

The small ones are just a vacuum seal and the large ones are just for mechanical mounting. None of them have anything to do with sealing anything under pressure. > The o-rings that came off the rusty injectors were as hard as bakelite! Those are the ones which break when you squeeze them. Then you throw them out. ;-) -- ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
