I just installed a fuel pressure gauge and used a "T" adapter at the end of the fuel rail for the sending unit. I removed the schrader valve before attaching the adapter, then I put the original fuel rail end cap on the end of the adapter, but now it leaks (a lot). With no schrader valve, the end cap can't hold the pressure.
Can I put a sealant on the adapter threads and if so, what kind?
Sorry for the very basic question, but I'm a computer geek.
