Is there a minimum distance for bends to be away from the fittings that you'd recommend? For example coming off manifold to a bulkhead to pass through the false floor. Is there a minimum length for the 90 degree bend to be (aside from the benders capability) or is that not an issue? I currently have a few of mine at 2.5" 90s and I'm wondering if the bend itself is to close to the fitting; maybe I should extend the piece that is actually going into the fitting or leaving the manifold. So instead of a "stub" 2.5" 90, mark it xyz distance from the end to give myself a straighter section to put into the fittings. All PTC bulkhead fittings so that's why I'm wondering, not secure like the compression ones.
Each fitting is different. Take some tube and experiment with distances and clearance. I stick to similar fittings so all my templates apply. If there is a major change i make new templates.
Can a 1/4 hardline fit to a push to connect fitting? Where do u buy dot approved hardliners? Can ss hardline fit my setup? I only need less than 3 feet I will mount on my setup to top of my trunk board.
