I need to replace the fuel vent hose on my 2000 Ranger. It goes from the filler neck to the fuel tank and appears to be 3/4" in diameter. The problem is that I can’t find any fuel hoses in this diameter at any auto parts stores. Are there any alternatives? I see heater hoses in this diameter, but I don’t imagine that would be a wise choice. Ideally, I need to find something locally this week. Any suggestions would be appreciated.
It seems a logical step would be the parts department at the ford dealer.
+1 to Volvo’s post.
Here in North Mississippi large diameter fuel line is stocked at both NAPA and O’Reilly’s.
You can also order large diameter fuel line from Jegs or Summit Racing. If you want local, use some heater hose until you can order a proper replacement.
That’s just way too easy 
After all you can’t put off doing the job if there is no waiting for finding and receiving parts if you just pick them up at the dealer.
Just cut to length.
