gsi marc Posted February 17, 2010 Share Posted February 17, 2010 just wondering about replacing the fuel lines on my 2.0 injection b series manta, do they need to be steel or copper or could i use the newer plastic type lines. Had a quick look whats available on ebay, mine dont look too bad but have been re joined at some point with rubber pipe and jubilee clips, and could anybody tell me the diameter pipe i need to buy, any help much appreciated thanks (marc) Quote Link to comment Share on other sites More sharing options...
mantadoc Posted February 17, 2010 Share Posted February 17, 2010 If they're joined under the drivers seat it's normal. I think I used 1/4" copper brake in 2000. Rigid so easy to bend to follow old clips and route. Quote Link to comment Share on other sites More sharing options...
manta400john Posted February 17, 2010 Share Posted February 17, 2010 The plastic stuff's a doddle to use, you don't even have to take off the fasteners...just thread it through(after you've cut off the old ones obviously!). If you're carefull it can be had for free at some scrappy's I've used copper before but never again. Quote Link to comment Share on other sites More sharing options...
mantadoc Posted February 17, 2010 Share Posted February 17, 2010 I've used copper before but never again. Dunno why, I've always used copper, once dirty looks original enough, fitted mine in 2000 and have been on and off no problems without getting bent out of shape. Fitted it on the '90s on my brothers Coupe and my deceased '88 as well. Even used the brake pipe flare tool to single flare the ends like original. Plastic works too though.

manta400john Posted February 18, 2010 Share Posted February 18, 2010 Dunno why, I've always used copper, I use copper therefor everyone should I use plastic 'cause I've tried copper No offence, each to their own eh. Marc,good luck with it whatever pipe you use. John. Quote Link to comment Share on other sites More sharing options...
andyc Posted February 18, 2010 Share Posted February 18, 2010 Always use the proper GM coated steel pipe, use a pipe bender and take your time and you get a nice finish Try to get the old pipes off in one go and use as a pattern Andy Quote Link to comment Share on other sites More sharing options...
keith1200 Posted February 18, 2010 Share Posted February 18, 2010 (edited) Can I just say? all the above is correct I removed my (in good nick) GM metal ones as I was welding in the area! Could I f**k get them back on!!! I gave up and used cooper piping instead, if memory serves me correctly! it was 10mm. Idealy i would have like to use the Gm ones BUT cooper work for me. Hadn't considered plastic pipes tho and I suppose it depends on price! roll off cooper cost me a 10 spot. (central heating stuff) Keith PS you'll need to buy new grommets or use rubber pipes (sleeve) for the pipes going through the jacking point.

gsi marc Posted February 18, 2010 Author Share Posted February 18, 2010 Thanks guys for the replies, i guess the choice is mine, copper,steel,plastic oh my head hurts. i'll just have to price em up, I could go with the plastic because my cars about as original as katy prices breasts, never thought about the sleeves to run them through the chassis either as mine did'nt have any, many thanks (marc) Quote Link to comment Share on other sites More sharing options...
maher the hermit Posted February 18, 2010 Share Posted February 18, 2010 Ive used 8mm plastic on my mantas for years so much easier to fit Quote Link to comment Share on other sites More sharing options...
gsi marc Posted February 18, 2010 Author Share Posted February 18, 2010 thanks for that probably going to go with the 8mm plastic then for the easy fitting Quote Link to comment Share on other sites More sharing options...
mantadoc Posted February 18, 2010 Share Posted February 18, 2010 I use copper therefore everyone should Make your mind up, thought you used plastic? Plastic is ok you know. PS you'll need to buy new grommets or use rubber pipes (sleeve) for the pipes going through the jacking point. I recycled the old flexi pipes from under the drivers seat for grommets. It's good for the environment and it's ok for you Quote Link to comment Share on other sites More sharing options...

Retro Power Posted February 19, 2010 Share Posted February 19, 2010 copper or plastic, both work well, you want 5/16" or 8mm (8mm copper microbore plumbing tube works well and is resonably priced, as does 5/16" kunifer, though this is a tad pricey) Quote Link to comment Share on other sites More sharing options...
mantasrme Posted February 19, 2010 Share Posted February 19, 2010 I use Kunifer brake pipe in 5/16" (which is 7.9mm) purchased from my local Motorfactors in a 25ft roll (think its standard brake pipe on smaller wagons etc) Then short length of rubber fuel pipe split lengthways to get through jacking points etc Gives much better protection than grommets (also easier to fit with a bit of silicone spray inside ) Quote Link to comment Share on other sites More sharing options...
