I have a Punto 1.2 Sporting 8Valve & I need to test the fuel pressure as I suspect it is low. I have a fuel pressure gauge but:
1. Can I test this via the pressure relief valve on the end the injection bar?
2. Does anyone know what diameter & thread this is? It is very close to a bicyle schrader valve but not quite the same thread.
3. Anyone know where I can get a push on pipe union with the correct thread on the other end?
4. Do you remove the valve core when testing the pressure?
5. Again this is a non standard size, so is a removal tool available?
:bang:
