I found a fuel leak at the fuel inlet schrader valve. My question is, do I a schrader valve replacement with an o ring that’s specific for being used on a fuel line or will any old Schrader valve work?

necesito su ayuda si a alguien le a pasado algo parecido, simplemente se apaga cada 15-20 minutos encendida, no hace algun golpe o ruido solamente se bajan las rpm y vuelve a encender perfectamente despues de dar marcha, todos los niveles estan bien, bateria,marcha y alternador nuevos…

Also it’s a 4l60e I forgot to say that

I have to put it in first manually and then put it in drive but after that it stays in second and won’t keep shifting. I had taken it to a service center to get some leaks and idle issues fixed, and cooling issues (she’s a fixer), and the mechanic said he doesn’t do transmission work.

Anyway, what could it be? I do not have the funds for a rebuild right now. Someone told me something about it maybe being a shift valve, he had the exact same issue.

Drove all day fine no overheating, get home and saw temps starting to reach 260 came out and saw this. Any suggestions?
