[Vwdiesel] VDO gauge adapters

Well, I got my box of gauge goodies today, oil temp, pressure, and boost, 
from CIP1.com. Also included are the oil temp sender #323 423D, which 
says 300F, M10x1, and a T #240 850D, which also says M10x1 "VW 
Application" on it. 

However, it appears the temp sender uses tapered threads, likely 1/8" 
NPT, which will go in 2-3 turns before binding. Also the T uses the same 
taper on the male portion, but it correct M10x1 on the two female ports 
(confirmed with a VW oem sender).

This seems very odd to me. Is there such a thing as M10x1 *tapered* 
thread, and if so, is it the same as 1/8" NPT? Is it safe to force a tapered 
thread into a straight sender hole? (if so, what torque is safe?). Or did they 
somehow mess up?

Before I call CIP, I'd like to know if this is normal, or have I got the wrong 
parts? Thanks.Shawn Wright
