montyjn Posted March 30, 2017 Share Posted March 30, 2017 Unfortunately, my defender failed its MOT last week for a leaking fuel line - the metal pipe running along the chassis between the tank and the filter/engine. I can't seem to find the part for sale anywhere (1987 v8 110) and since I need to replace one, I may as well replace the other too. It seems from reading up on here and other forums, that replacing the pipe with nylon hose and stainless steel p-clips is the way to go.. A couple of questions: 1. What is the internal diameter of the fuel pipes as fitted (6-8mm)? 2. Is a nylon pipe preferred over rubber for modern unleaded? 3. Given the body is on and the nylon/rubber pipe would have a much larger external diameter, how would I fit the p-clips into the chassis? 4. I understand trying to replace the pipe with copper piping is undesirable due to the brittle nature of copper over long distances. Does that sound right? Thanks in advance!

Ex Member Posted March 30, 2017 Share Posted March 30, 2017 3/8" nylon tubing would be suitable and what is used on most Defenders and there are stock clips for the chassis. Nylon is suitable for all fuels. Hose will work as well, but costs a lot more. Quote Link to comment Share on other sites More sharing options...
neil110 Posted March 31, 2017 Share Posted March 31, 2017 (edited) the part numbers I have are: NTC2263 NTC2064 Sadly both parts are obsolete. Though Hobsons of Louth are showing stock on NTC2263 http://www.hobsonindustries.co.uk It is interesting because I have an earlier V8 with twin tanks, external pump and chassis mounted filter where all the fuel pipes are nylon and mounted in plastic clips which push directly into a selection of holes provided on the chassis top rail If you look up a diesel specialist in yellow pages or similar they might be able to make up the nylon pipes with the necessary bends and fittings Edited March 31, 2017 by neil110 Quote Link to comment Share on other sites More sharing options...
