ECS tuning carries the [http://www.ecstuning.com/stage/edpd/pagebuild_v2.cgi/?html=learnmore.html&productID=748 Samco F-hose].

==Notes==

Part number 078-133-784BG is listed for the AZB, and is probably not an F-hose.

Note that when replacing the F-hose, the [http://www.vagcat.com/epc/search/11/078133587/ coupler] (number 29, part number 078-133-587) is very brittle and might break.

Fortunately, it is NOT a check valve, only a coupler, and can be replaced by random parts and some teflon tape.

Alternately, [http://www.ecstuning.com/stage/edpd/pagebuild_v2.cgi/?html=learnmore.html&productID=5350 ECS tuning] carries replacement couplers.
