Chambers Posted February 25, 2018 Share Posted February 25, 2018 I will hopefully soon be fitting the fuel pipe (tank to carb) to my Spit however I've scrapped the old one. I am wondering, am I better fitting copper as original or is braided the way to go? Also, could someone let me know the correct diameter. I have seen both 1/4 and 5/16 listed.

Steve AKA vitessesteve Posted February 25, 2018 Share Posted February 25, 2018 Bigger would allow for more flow if needed in the future if you improve the engine. Braided lines can hide problems at least with copper you can see where the fault actually is. Also the rubber in braided hose can be damaged by alcohol in petrol - I know fuel line should be OK but some line still suffer and you can not see the damage inside the pipe.

Chambers Posted February 25, 2018 Author Share Posted February 25, 2018 Thanks, Copper it is then and I'll go for the larger diameter Quote Link to comment Share on other sites More sharing options...
Clive Posted February 25, 2018 Share Posted February 25, 2018 The "larger" size was 5/16, and that is almost identical to 8mm. Screwfix sell rolls of 8mm copper tube for a very reasonable price. I recently bought some to put new fuel lines on my Toledo. Any rubber hose needs to be R9 rated, and from a reputable source. There is much fake hose about, which quickly disintegrates. Most braided hose carries no rating at all, so unless the seller can guarantee it is R9 or better, do not buy. Many sellers say "it is ok for fuel injection", but that is not enough!

marktheherald Posted February 25, 2018 Share Posted February 25, 2018 I had some surplus PVC coated 6mm i/d copper pipe from when I fitted an LPG kit to my Midge. It's looking good on my Herald chassis, just needed 9mm 'p' clips. Also available in 8mm i/d. Probably available from any reputable LPG system supplier.
