As per title really. Need to know what the internal diameter is for the fuel hose so I can source an in-line adapter for my fuel pressure gauge? Also, am I correct in assuming that all the fuel lines in the car are the same size?

Thanks.

I just recently had to replace the hose from the fuel tank pipe to the fuel filter and fuel filter to the fuel rail. I used 7.9mm I/D hose as this looked the best size match to the piping it replaced. It fitted nicely too !
