To be completely honest with you, I wouldn’t go with pure viton for the fuel hoses. I would only use viton 1/8 return fuel lines that go in between the injectors. I’ve used SAE 30R9 hose from both GATES & Goodyear for years on my car and clients cars and they have worked out great. I believe they have a small amount of viton inside the hose, but are not 100% viton. So they are way cheaper and can be found in almost all auto parts stores. Do make sure you replace the fuel hoses that our coming out of your diesel tank. Because they are most likely 20 years old too.

Good luck and be safe
