Shannon-- or anyone else who went the discounthydraulichose.com route... can you help me with what lines you chose and fittings? I see 3/8" for supply and 5/16" for the return.
Not sure what product or length that you ordered. Any help on this would be appreciated-- buy once cry once. Dont want to be changing them out every 5 years.
Thanks in advance.
It took awhile to figure all this out. Hopefully this will help prevent some frustration.
A little history: The AN standard is a military fitting standard developed in the 1940's. The specs on AN are crazy precise and while that's great for military and aeronautical industry, its completely overkill for automotive applications. The 37 degree JIC standard is an SAE standard for high pressure hydraulic and fuel delivery up to 10,000psi. The fittings are interchangeable between AN and JIC... the "slightly" lower tolerances for JIC means being able to get the fittings MUCH, MUCH cheaper than AN fittings.
One thing you'll need to do is to make a 37 degree flare, which is the standard for AN and JIC... most flare tools can only do 45 degree so understand that when you go shopping for a tool. I already had an Eastwood tube flaring tool so all I needed to do it purchase the 37 degree die for it.
I used 3/8" line (also referred to as -6an) for both the supply and return lines. Why? I could buy one size of fittings and hose lines. The price difference is negligible and its just easier.
Once you have your line cut, you need three things to join a tube to an AN or JIC fitting (Assuming you use 3/8" tubing):
- A 3/8" tube sleeve (Link here)
- A 3/8" tube nut (Link here)
- Any JIC or AN fitting like one of these as an example (Link here)
You then put the tube nut on the tube, then the sleeve, flare the line and bolt it up like this:
The fittings you need are really going to depend on your fuel rail configuration and where your tank outlet is. My tank outlet comes out inside the trunk, so I go through the trunk with a bulkhead fitting then follow the passenger side inside frame rail, up to the rear of the engine bay, out to the fender-well routing under the front suspension, then back into the engine bay right in front of the shock tower then up to the fuel rail (I am using a fuel rail from a 91 Mustang GT). The lines under the car are cut into three sections to make it easier to install and jointed with these (Link here
). Each time I go through metal I use a bulkhead fitting like this: Link here

. Click on the shape you need an pick out the 3/8" version of that shape.
Hope this helps! I'm sure I missed something so let me know if you need more info. I would take pics of my setup, but I've got it all torn out to paint the undercarriage.
