Is there a special tool for removing the fuel pressure relief valve? Part Nbr 993.110.217.00 It appears to be threaded.
Backstory... I'm working on a 3.4 to 3.8 rebuild. While fuel rails are out, I'm replacing the regulator, injectors, and pressure relief valve & cap. Thanks!
Actually that Schrader valve is a size bigger than a standard tire stem Schrader valve. It is the standard size of an A/C refrigerant line Schrader valve. So an A/C Schrader valve removal tool will work perfectly.
In a pinch, I have used A/C pressure gauges and lines/fittings to test fuel pressure on those, A pressure gauge is a pressure gauge !!
Also if you can't find an anodized AN fitting, the brass A/C caps will work and be better than the plastic cap..
