ericobrave Posted June 19, 2012 Share Posted June 19, 2012 To save me searching - Where do I get plastic pipe suitable for the diesel from the tank to the pump etc and what two sizes do I specify ? Currently rebuilding 1991 110 200 tdi Thanks Quote Link to comment Share on other sites More sharing options...
mmgemini Posted June 19, 2012 Share Posted June 19, 2012 Any local diesel specialist should stock it by the roll. He will advise the sizes for you. Quote Link to comment Share on other sites More sharing options...
simonr Posted June 19, 2012 Share Posted June 19, 2012 Trouble is, Mike, it comes in different sizes depending on model & year. 3/8 and 5/16" for return are common, but so are 3/8" for both, 8 and 10mm. I doubt a local specialist will know precisely. I would also like to know for definite so I know what size fittings to supply with the X-Eng fuel lock about to launch. Nobody has been able to tell me anything more precise than "you'll have to measure it to be certain". Si Quote Link to comment Share on other sites More sharing options...
Paul Woodward Posted June 19, 2012 Share Posted June 19, 2012 I got mine on eBay. It was imperial on mine 5/16 and 3/8, that's on a 1984 spec fuel tank from a 90 and a 1995 300TDi engine. You do need the exact size, 10mm pipe wont work on a fitting designed for 3/8 pipe. To fit the unions I drilled a hole to suit the pipe in a hard wood block. Cut the block in half through the hole to make two semi circular dies. Warm the end of the pipe in some hot water and clamp between the dies in the vice with about 25mm poking through. Start the union in the end of the pipe and knock it in with a mallet, hold the union square with pliers while you hit it. Quote Link to comment Share on other sites More sharing options...

Si Fuel lock that sounds interesting when can we expect more info?Sorry to Hijack Quote Link to comment Share on other sites More sharing options...
C18RCH Posted June 20, 2012 Share Posted June 20, 2012 Try your local agricultural supplies place. That's where I got mine. They had everything including banjo connectors and most sizes of fuel pipe. Quote Link to comment Share on other sites More sharing options...
simonr Posted June 20, 2012 Share Posted June 20, 2012 Fuel lock that sounds interesting when can we expect more info? As soon as I have an accurate spec for hose and fittings versus vehicles and have sourced them! I'll have one of the production valves with me at the Bristol & West show this weekend. Any more info on what tube sizes people's vehicles use would be very valuable! I've bought non return valves for 5/16 and 3/8 OD pipe with a 50/50 mix and will probably do the same for the valve. The trouble comes when someone says "I have a 1991 V8 90 - what size do I need? I don't know how to use a Ruler to measure myself" I need to have an idea at least!

Ex Member Posted June 20, 2012 Share Posted June 20, 2012 It is just nylon tubing. Any hose place. It is very cheap. Just measure the outside diameter to figure out the size you need. Quote Link to comment Share on other sites More sharing options...
