I’m using a 904 trans. Rarely, if ever do you hear about them violently exploding at the drags. I’m sure it has happened but I don’t recall ever reading about it occurring in any sort of dramatic fashion.
OTOH, 727s do have more of a tendency to blow up. At the level most of are at though I’d say not enough to ever be concerned about. The rule is for that one stupid time it could happen even though for 99% of the people racing Chryslers that would be never.
Regardless of what the rules say, would you trust “steel braided hose” to be sufficient protection against a wayward ring gear? Or, would you want to figure out how to facilitate installing a 16” length of 1/8” wall steel pipe in that area?
Again, I‘m not interested in fabricating some sort of shield just to be able to run the line through that spot. It is pretty tight quarters next to the torsion bar mount. It’s also right next to the header collector which radiates heat. Nothing like cooking your fuel inside a heavy steel tube before it gets to the throttle body. Again, no method is perfect.
I will also argue that the factory routing does in fact expose the line to road debris to some degree. (Ok steel hard line vs. flex hose with aluminum fittings but it’s not a big stretch.) I’d say it’s especially true where it crosses under the right rear frame rail and from the outer pinch weld to the inner frame rail. Where it runs along the inner frame into the engine bay there is nothing between it and the road. Can you justify saying that one 6” section of hose I have in the wheel well is any more susceptible to damage than the OE line?
