Like the title says, this thread is on swapping the quick disconnect lines at the tank/pump (aka- fuel feed and return lines).
I have the resources and some knowledge on doing this from my time in Marine aviation. I have done this on other fuel injected vehicles. I do not like the quick disconnect lines and accidentally broke the two feed and return nipples on the fuel pump housing. I wasn't being as careful as I should have been and since I already have performed this on the oil cooler lines on my automatic transmission and engine oil (and added an external oil cooler), why not do this as well?
I just so happened to have a -8 AN to 5/8 x 18 inverted flare adapter. So, I pulled the feed line from the fitting at the adapter where it transitions to the steel tubing. I also plan to make the new lines a little longer to allow for more room to work in the future.
I will also fabricate a -6 AN return line.
My plan of attack is to put -8 and -6 bulkhead fittings on the pump housing. The fuel feed will have a -8 female to female adapter to a male to 10mm barbed fitting that will connect to the feed tube from the pump.
For the return line, I plan to just let it flow directly from the bulkhead fitting. We will see how that works out.
I purchased a lot of my material (hose and most fittings) from siliconeintakes.com . The fittings that they provide are aluminum. On a side note, I fabricated my own intake pipe system from their silicone elbows and aluminum connectors. They provide real nice silicone hose and tubing.
The -8 and -6 to 5/8 inverted flare fittings were purchased on amazon.
The reason for posting this was because I haven't found anything on this and wanted to see what you guys have done.

What had happened is that I had moved the gas tank to the side to gain better access to the fuel pump wire harness and the two lines broke off....
