Summit racing stainless braided dual feed fuel line for sale.

As I mentioned above I had it installed on a summit racing 750cfm carburetor not a holley.
I imagine that IF there is a difference in length between the summit carb and one of the two part numbers you mentioned above. Worste case scenario you would either have to shorten or lengthen the center line to use it for one or the other. Or could be a direct fit. Not sure. But like I said... Worste case you would just need to shorten or lengthen the center line which is not that big a deal.

Let me know if your interested. Thanks
