Hi Tyler,
I had this discussion about 30 years ago with a very smart bloke at Carac ( the go to auto parts store around here, all the rodders and modders went there) here in Dandy and he assured me it was fine to use, might not last quite as long as dedicated fuel hose but these days with all the chinese junk stuff kicking around who knows how long anything will last. Nitrile hose is fuel/oil resistant so there should be no problem. Anyway your hose will outlast any mower you put it on as long as you don't use it on a 2 stroke Victa because it might still be around in another 100 years. It might need replacing before then.
