Ok I went ahead today and picked a fight with the wrong hard plastic line under the hood while changing the fuel lines. I ended up killing the hard plastic oil line to the pressure gauge. Well I look up the part and I see it listed at 70$ but I doubt it is available and I don't want to hound dog any more parts, it isn't very fun.

The hard line is a barb fitting and I thing I can "rebuilt" it using teflon tubing. I measured the line and it seems to be 1/8ID which is a pleasant surprise. I am thinking of using some PTFE teflon tubing which will be a nice tight fit. The oil pressure gauge runs to 3 bar so around 45psi.

I think I'd need around 5 or so feet to run to the instrument cluster. I also might be able to use polyethylene but I need to see if it can handle the heat and pressure.

Any tips or suggestions?

Have you looked at Pegasus's site? I know they sell tubing by the foot.

Try finding some Tygon tubing. I use it for industrial instrumentation lines. They have a variety of types for almost any fluid transmission application. It can work with barbs or compression fittings and you should be able to find what you need at a good price.

In reply to benzbaron:

Make sure whatever you get it's rated for the temp range. If it gets soft when it heats up and spits itself off the hose barb, you'll need $400 worth of elbow grease to clean it up!

Cool thanks for the replies. I'll order some up. I'm going to try to patch or plug it in the mean time.

Thanks again, I'll have to hit up the McMasterCarr website as I don't have their cubic foot book.

mcmaster is good as already stated. newage industries is where people in the hose world go for tubing. Tubing is requested by OD and wall thickness. Hose is specified by ID. (a little hose training - sweet?)

Pete learning how to buy seems to be the most difficult part. Some people don't like us ignorant suckers either.

So I guess if I'm getting tubing it would be 1/4OD and 1/16wall thickness. Good to know. The stock line is slightly thinner than 1/4.

There is also a DIN number on the stock tubing so maybe I'll look for that if I can find it. I am realizing that buying new parts for everything that breaks is out of the question so I am forced to repair. It is getting to be a pain to even find the parts and when you do they cost too much to afford. A piece of 5ft hard plastic tubing with fitting on each end is 100$. The fitting are barbed leading me to believe an easy repair is possible.

If you can take it off and go to a local hose shop they may be able to set you up with eactly what you need at a good price without guessing at the right size and material. Our local shop is very good at giving me the correct pile of hoses tubes and fittings inspite of my ignorance. usually while I wait for less then the dealer whould want.
