http://www.dieselmanor.com/dm_products/FTG-MFD.asp This is what I used, seems to be holding up pretty good. Little pricey, but you get what you paid for. Looking at you sensor tip, I dont know if it will work though. Is it 1/8 npt?

 

3/8 npt for the tee fitting. The sending unit I think is 3\8 flare. Not too sure though

 

Ya it is different on your machanical gauge.

 

Why cant you flare the ends of the tubing you already have and screw the flared ends into the fitting?
You maybe able to rent flareing tool from Autozone or buy one.
Ok double checked your install picture. The line comeing off the tranny may have to be replaced.
Cut new line to length flare then bend to shape.

it has a Swag-loc in it. So no need to flare. It cinches the line when you tighten it.

 

Compression fittings are junk. They always leak eventually, especially when subject to vibrations (like when used on a vehicle). Do it right and use flare fittings.

 

I assume your talking about his compression fitting, I know how they work.
I ment get rid of the compression fitting all together and replace with flared ends, much better against high pressure.

Yep, Had that problem, was told by someone who was supposed to know what they were talking about. Now I have a new trans line that I cannot install (never done it before) Plus the new line has a female fitting and the old line has a quick connect fitting. WTF? Heres some pics of it. Any one know why this is? The line runs in the same spot and to the same port on the trans, just different fittings. Also cannot figure out how it will run between the exhaust and trans without removing the exhaust..... What a day!
