Needs a little work to fit properly
Purchased to replace the hard tube that went from the fuel pump to the carb on a 351 Ford. Because the tube was so long I had to route it around the distributor and then back to the carb inlet.The carb is a Holley model 4160. When routing you need to be careful because the hose will kink rather easily. Also had to re-tighten the flare fittings a few times to keep them from leaking. Seems to be working ok now.

Unsafe.
The media could not be loaded. I think the regulators who designed this need to be fired. Buy sae j1527-15 hose that does not have braided covering and make your own. This should be recalled.
