I ordered some stuff from UK: http://www.ssldieselparts.co.uk/ I bolted on some hoses and parts to find out if all would fit right places and easy to access for maintenance. No hose clamps/clips yet. To keep the original tank necessitates fairly thin walled hoses. The hose from the injection pump is normal Gates NBR hose and from the tank is Tycon type PVC hose. That particular hose is 1/4" OD, but I really would need 5/16" (8 mm) ID type. But it bends pretty well. I could not use two standard NBR hoses, they simply would not fit past to each others. Pekka |

I haven't to parts yet, looks they are not sent. Meantime, I have been putting some fuel hose samples on HD-PE jars for immersion test. First set I'm letting them to stew on standard mineral diesel (no bio diesel components). After exactly 25 hours in about 30C looks like Gates 3225 NBR/PVC and Oregon 07-258 have no dimensional or apparent changes. However ordinary "clear" PCV and cheap "FUEL RESISTANT -15/45- made in italy" fuel lines have some noticeable dimensional changes and they feel noticeably harder than non-marinated samples. I have cut some samples more and I'm thinking fastening them on an alternator under car hood to check if outer layer will deteriorate on ozone and/or heat. Then I need to hung some samples out to check effect of UV, but it's pretty useless now - we got very little of sun light. Any other ideas ot pointers for immersion time/temp. values? Pekka |

After 6 days in standard mineral diesel oil small, but clear changes are evident. Cheap/no brand PVC and "rubber" fuel lines are clearly harder to touch, but dimenssional changes are smaller than I anticipated. Both brand lines Gates NBR and Oregon PVC are unchanged as far as I can tell. My brother found one piece of interesting (fuel line) hose from his inventory. He said that he got it 10 years ago for power steering and automatic transmission. They sais that the hose has teflon lining and automotive grade exterior. Unfortunately this hose has no manufacurer markking, only this marking: ID 3/8 WP 300 PSI 10230705 ID 3/8" is pretty evident, but the pressure rating is funny, about 20 bar, it would hint standard compressed air hose, but are there any teflon lined compressed air hose? Or maybe he just gave me wrong hose? Pekka |

When I was rebuilding car brake systems with CuNiFer lines the "goto" flexible hose supplier was Goodridge: http://goodridge.brakes-hoses-fittings.co.uk/ Teflon/stainlkess/anodised fittings plus you can just buy the bits and make your own as they don't need a massive hydraulic crimper like wor hydraulis fittings need!

Hi Pekka, I found this info on Gates fluoroelastomer lined fuel hoses. There should be something in their range that will suit your needs.....OZ. Link: http://www.gates.com/oreilly/tech_tips/PermeationResistantFuelLineHose.pdf |
