I am running 2 fuel lines down tunnel.
one is flow, the other is return.

I also have got to run a 3rd for charcoal canister, about the same size as break line. (used for fuel fumes).

The problem I have is how to clip them down the tunnel, P-clips is one option, but with limited space to fix them.

Does anyone do fuel line clips with a single fixing (like on production cars) that will take the 3 pipes?

If so can anyone post a few links.
