The factory one looks like a nail, but a bit purtier when you take it out, though a stubby nail would work. I bought a roll of 1/8" Viton hose on ebay many years ago. From China, so I was suspicious, but appears to be true Viton. I use it for the short sections between injector returns and no more wet hoses there. I use the cloth-braided rubber hose for the longer run to the fuel filter since I still have a roll to use up. It starts seeping after 3 or 4 years, though less so at that location. It is stamped "Made In Germany", but who knows with all the fraud today. Once, I tried 1/8" silicone hose at an injector before I got the Viton hose. After a week, it had become swollen, as others have found for many alternate hose materials.
