As long as the tip isn't in danger of falling apart, this is fine. You can even remove the plastic tips completely and omit them. I probably have some spares here, too. You should worry about whether you bent the center pin or not, but if the plastic tip was in place that would be hard to do. I think that's one of the main functions of that piece. > I've got 4 NOS injectors still bagged and in their original wrapping, > plus I've got 4 used ones that honestly have been sitting around- two > which I won't use because they're rusty and crusty and possibly exposed > to the elements, and 2 that look very clean but weren't likely stored > with kerosene in them like Jim likes to recommend. But they look very clean. Keep the new ones on the shelf until you absolutely need them, which you probably never will. With care, the service life on these is very long. My preference is to use up my oldest parts first, since the alternative eventually leads to a stockpile of old dubious parts. With injectors, you have to worry about whether the O-rings in them will leak when you install them after a long time. BTW, it's almost never too late to start storing used injectors in kerosene. -- ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
