Does anyone know what thread pattern it is? TASauto has a 70 dollar fuel psi gauge you can mount there but i found this on the home depot web site and was wondering if i could get an adapter to have it fit. But i need the thread pattern of the service port first. http://www.homedepot.com/webapp/wcs/...ctId=100111543

 

actually, i can just unscrew the top of the service port and crank a nipple on there instead probably. so if anyone has the threads for the top of the bolt, let me know.
