BN6 / Smash my fuel and brake lines..

[Junkmanmitch]

is this a design flaw or poor instillation from the previous owner of 1958 BN6? I got fuel and brake lines exposed to the under frame and are smashed to heck. I do not see any alternate routes to put them without drilling holes in the frame. Would this be ill-advised and ruin the structural integrity of the frame? I'm thinking 3/8" with a grommet...Am I not seeing the correct route these line should be going?

Big Green's photo shows that on stock Healeys the lines and battery cable run inside of the main frame rails. The bottoms of the cross members are elevated somewhat from the main rails.

On the factory rally cars, I've read that these lines and cable ran inside the passenger compartment. The texts that I've read didn't say whether there was any protection or separation from the passenger compartment. They were, of course, subject to severe beating on gravel roads at high speeds.

Well for one, the "copper alloy" pipes can be smashed with your fingers! The OE steel pipes were of a stronger wall strength than the copper frequently used today (copper used to be illegal to use for brake lines, so maybe saying "copper alloy" makes it okay...?).

I recommend using the stainless steel pipe sets available from places like Classic Tube: https://www.classictube.com/shop-online?page=shop.browse&category_id=98

Note: you might have to choose some pipes from a different model to get a complete set (if you have front disc brakes for example, use the 3000 BN7 set of pipes).

In the point where the pipes are more exposed (near the rear axle) it is indirectly protected by wheels diameter
probably your damage was produced by wrong lift in the past

is the exhaust system that is more exposed especially on the front of muffler

Hans, it looks to me like the pipe connections to the chassis are turned the wrong way. They should be reversed then bent up towards the chassis a bit.
