Fuel Return Line Questions Options

[friethmiller]

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.

I would use a true circular hose clamp.

Early fuel injected Datsuns had FI clamps that are wonderful. I scrounged many...

Don't use normal worm style clamps.

As long as you can find the proper OD size a spring clamp works well too.

Both of those lines right there have extremely low pressure and thus are not as critical as "between fuel pump and regulator".



I wanted a beader set myself. Did some research a few years back.

The Hawk is RIGHT!

$200+ per size and I want 5.

1K+ worth of beaders would have marital consequences...


Also, I have never found a hose to tube sealant that worked without damaging stuff down the road.

Normally I use my spit to lubricate the hose before installation and, it seems to form a light seal by itself.
Soap might do same thing better.
