ok. . I was looking at Geno's filter cap for the fuel... its has a tap on top to add a pressure sender... now. . will that show pressure before the filter or after?? also I was thinking of adding a exhaust temp gauge... I have an 05 where do you mount it in the exhaust? I was looking and hoping that there was a plug I could remove... but no dice!!!!!!!! thanks in advance... . Garth
