Working on my 70 914-6 resto and the plastic brake reservoir feed lines that I have need a little work in the bends for a better fit. I tried to use a hot air gun but didn't have a lot of luck with the bends in the plastic lines. Anyone have suggestions?

Yeah, get ready to fill the swear jar. Worst job on my project so far. (IMG:style_emoticons/default/mad.gif)
I did manage to use a heat gun to get the bends in but it takes time, patience, and patience. I didn't get the bends perfect and don't think it is necessary. Get them close and then use the metal strip hold downs to hold it in place. Getting those fittings that go into the MC on is where the swearing starts. There is nothing fun about those lines. |

Put a want to buy, should be easy to find some. Not an item that is sold very often, usually end up in the trash.

I've got mine correctly situated in the MC (yes, with considerable swearing) so not going to try to find a better fitting set. I think I only need to make some small progress. I probably did not heat up enough.

What makes you think the vinyl tubing was bent into shape in the first place?

 They were, NOS piece. It's Polymide tubing, same material as early CIS fuel lines. |

I agree, that they came that way (bent) from the factory.
I recently bought some factory tubing from the dealer and both pieces had similar bends as the pic above. IMHO....The type and number of bends just wouldn't happen naturally to a straight piece of plastic tubing over time. |

Polyamide is nylon. Insert a thick gage copper wire as a mold. Use a heat gun and hold it until it cools down.

You can also use spring benders. Slide the tubing into the bender, bend tubing to shape, heat bender enough to warm nylon tube, let cool with the bender on it and remove bender. It should hold the shape.
