A little tip is to put some gasket maker (just a very small dab) on the outside end of the tub and this will almost ensure a perfect seal. You can use the same stuff you used for the gas tank assembly. Otherwise I found these tend to leak a bit with out it (3 of my 4 did without the little dab). Overall, much easier than a flaring tool and fittings.

The right fittings for the job.
Looking for the right adapters to use with aluminum fuel line? Then look no further than these adapters from Russell. Designed to connect aluminum tubing to -6 or -8 AN adapters, their unique crimp design eliminates the need to flare the tube, thus saving you precious time. They're available with both male and female ends for 3/8 in. or 1/2 in. diameter tubing. " |
I used these fittings on the 1/2" aluminum hard line from the tank to the engine bay. Another thing to watch out for is how much tube extends past the brass olive before you tighten it up. I had trouble getting one to seal properly. The olive was compressesd onto the tube OK but the end of the tube was bottoming out in the fitting and preventing a good seal. Trimming a few mm of the end of the tube fixed it up.
The rest of my lines are flared with tube nuts and they seal great. Not difficult to do either.
