I have a 1999 E300 TD. The seals in my injection pump are leaking like crazy. I think I'm leaking more fuel than I'm burning. Seems like a common problem as a result of using ultra low sulfur diesel.

Anyway, ordered the Orings and crush washers, but I need the splined socket to remove the injectors on the pump side. Some retailers are calling this a "32 spline socket" and some are calling it a "33 spline socket". Which one is it? I imagine if it's one spline off, the socket wont fit.

Can someone tell me which is the correct socket size and best place to buy it?

As always, you guys / gals are awesome. Thanks for the help!
