TEA20 FUEL LINE

kaesark · Jun 29, 2018

Have purchased some brand new 1/4" copper tubing to make up a new fuel line as what I took off was a complete dogs breakfast. Would any of you good folks have a picture of what direction the fuel line should follow and if possible where, how and if it is secured from carb to fuel tap.
Appreciate any feedback.

1/4" line is too big Kaesark , try a smaller size available from air conditioning suppliers . You need small compression fittings to connect this line to the tap and carb . I'll try find some photos for you . Copper will work harden over time and may crack but mine has lasted for years with no trouble. It also transmits heat more than steel so route it away from the manifold as much as you can .

6mm outside diameter is what was there before do you think I should use 3/8

Sorry I meant 3/16

You can see the copper tube I used in this photo Kaesark , I can't recall the exact size but it was the closest to the original steel tube that was fitted from new at the factory .
It is difficult to bend such small diameter tube without the correct bending jig , heating it helps a bit because it is sometimes work hardened when being formed .
The compression fittings are seen at the carburettor inlet , the brass barrel nut crushes a small olive onto the pipe and seals the joint tight , the same happens at the fuel tap end .
Notice that I ran the tube low in order to keep it away from the manifold , it does get hot but as yet I've not had any vapour lock . I bought the tube and fittings from a specialty hose and fitting suppliers that supply air conditioner and hydraulic services .
