Wrightwood Racing oil pump square ‘O’ rings

[Tippy]

Are they all the same? Wayne’s book shows green ones and orange ones and Bentley states there are 2 sizes.

Aren’t the Wrightwood Racing ones all the same size?

[BURN-BROS]

There are 2 sizes Wrightwood supplies . scavenge and the top two on the cooler is smaller. supply side of pump and cooler is larger diameter

[proporsche]

[Tippy]

Thanks guys

[Tippy]

I assume the ones in the low end kit are 1 for case to case and the other 4 for the pump???

[Tippy]

I have my cases together, and both the Bentley and Wayne’s book mentions 2 sizes.

Doubting myself right now

Inside the case is a large one behind the pump, two small on the pump and one between the cases.
Having had them displaced while mating the case halves I use aviation permatex to hold them in place.

I've used a little wheel bearing grease on them to help stick them in place while putting the case halves together or installing the oil cooler.
