Tracy, does the 323 088D sensor work with 1/8 pipe threads? The eGuages site says it is M10x1?
 
Regardless, if you are installing a sensor in an anodized aluminum fitting like Scott showed, I think you need a separate ground for the sensor, as the fitting will not be electrically connected to the engine block. Attached are some photos of how I did it, using brass shim stock. This is a Mitchell 400F sensor PS-211-9086 (not for use on Tracy's EM-2). It comes about flush with the inside of the fitting.

Try the VDO VW Rabbit sensor (eGauges PN 323 088D).  Same thread but has almost zero protrusion.  It has the correct resistance curve for the existing EM2 calibration.

Subject: [FlyRotary] Short Temp Senders

Hello All...

I ordered the following fitting with a 1/8" port for
senders.
http://store.summitracing.com/partdetail.asp?part=RUS%2D670340&FROM=MG

I have the EC2 which came with the VDO 323 057 1/8-27
300F sender.  The sensing portion of the sender is
1/2" long.  Which on the -8 hose pretty much closes
off the entire hose.

The threads on the fitting are approximately 1/4"
deep.

Thus, does anyone know of a shorter temp sender which
will not close off the hose?  The ideal length would
place the sensing portion of the probe only 1/8" or so
into the hose.

Any advice is appreciated.

Thanx...

-Scott
