Hey all,
I have no friggin clue where was best to ask this question, so figured I would just post it here seeing as it is for cosmetic purposes.
While I was installing my HKS fuel rail, I did up the blanking plug for the centre return line with a 6mm allen key. I was only intending to have it in there to stop anything getting in while I was working on the car, but of course I promptly forgot about it. When I then primed the fuel rail to check for leaks, this plug is now leaking. Only a tiny bit but I have this thing about fire in my engine bay, I'm sure you understand.
The issue is, when I went to take the plug out to put some Loctite thread sealant on it (as I should have just done when I put it in, don't know why I didn't), I discovered that the damn thing isn't actually a 6mm allen key, and I've now rounded it. So I need to get a new one. But, I'm not 100% sure on the sizes. Does anyone know if it is a 6.5 or 7mm allen key that I need? AND, I'm assuming that it is a -6 AN thread, same as the other fittings that came with the rail? So a -6 AN Speedflow plug would be perfect?
Thanks for any help,
Martin.
