My Red '74 (a.k.a Denise) is getting a return line but I'm having issues finding the right size return line hose to go between the tank and the SS line. I have a 5/16" (8mm) rubber hose that looks like it might work. Waited 4 days for Sierra Madre to ship a 7mm ID braided hose, which turned out to be > 8mm (just too loose). (IMG:style_emoticons/default/headbang.gif) I want to go with the 5/16" line but I really think both of these ends should be bubble flared. Has anyone done this? Anything to watch out for? Any other solutions here? I don't need these connections leaking or sliding off.
Also, I have a rubber washer on the return pipe and just a brass washer + screen in the feed. Is this normal? Can I use something like Curil T to help seal these connections? Thanks in advance.   |

The return is very low pressure. I would not change it. The engineers said it was good to leave the factory that way.

Dyno Yes, and that might be the way it goes. Planning to slow-roll through the FLAPS at lunch today. I'll see if they have anything to flare these ends. If not, I may just go with two fuel clamps. Thanks for all the input guys! Any opinions on sealant here? Go/No-go? It doesn't seem like a good thing to even try with gasoline. Thought I'd ask though. |
