Fuel Injector to Head Sealing - Double O-ring
I think I have a vaccuum leak at injector 4. I hear some intermitten hissing.
Flying Miata suggests using two Ford O-rings or one Mazda Injector Seat.

Anyone know the size for the Flying Miata Double Ford O-ring?
Or should I just go buy the OEM Seats?

I don't know the size, but they are pretty standard. Take an injector (an old one, if you need to use the car) down to the local HW store. Find the place where they have the rings, and try them out. Just fit them on until you find the size you need.

I was planning to do the DIY dual feed, and wanted to replace all the seals at the same time, just in case.

Looks like you have an extra car so best thing to do would be to send them to injector rehab

at minimum, they have a seal kit.

I went to NAPA and had them look up various Fords until I got the right injector O-ring that FM was talking about. I can't remember what engine it was exactly though. I doubled them up with stock injectors and it fit like a glove, when I went to RCs I could still use them, just 1 per injector not two.

Hey Guys
For the RC Injectors, do I need that grommet that goes behind the O-ring on the fuel rail side?
I'm going to just order all new seals from the dealers, just wondering if I need that. I don't see it on my car currently, but it may be inside the fuel rail.
