Hey all,
My 02 GT has a very slow leak from the heater hose where it mates with the fitting on the passenger side of the firewall.

The hose that is on there now is a used hose I pulled off a donor parts car.

I believe the O-rings inside the hose fitting are worn and I'd like to replace them before throwing real money at getting new OEM parts. The fitting itself is $85 and very hard to find.

My question: Does anyone know the size of these O-rings or have a spare heater hose laying around? The hose in question is the one that connects to the back of the intake manifold "nipple" and curls around to the right-most fitting on the passenger side of the firewall.

Thanks in advance!
