Dennis: Our prayers for your granddaughter.
The little O-rings for the shut off valve come with a Mann fuel filter. The thimble type filter does not seem to come with the 2 O-rings it needs. You have to ask Rusty to look them up separately. I've had trouble getting the thimble filter to seal without new O-rings. And I once had a shut off valve leak from its internal packing (or what ever is inside) and had to replace the whole valve.
