Default Fuel Line to firewall

If you get aftermarket fuel rails, how do you remove fuel line at the firewall so that you can run a 90 degree fitting from there to the fuel rails?

Thanks!

I don't know the exact name but the companies that make AN fuel fittings make ones that attach to the factory fuel line fitting.

Thanks!

So it is just like the side that attaches to the stock fuel rails.

Thanks for you help!

It is, but not the same. I bought one, "Aeromotive" and became concerned about the plastic clip that holds the lines together. I actually ended up using the stock piece and modified it to attach my hose to. The stock one is "all" stainless steel with 4 locking clips and also has a safety clip securing it to the line coming from the tank. With almost 60 Psi of fuel hanging over the exhaust, you could have a catastrophic issue real fast.

ZRCLONE, I understand exactly what you are saying. I am planning to start this project when the snow starts to fall, so I will look at other potential option, because I like the safety of the extra clip.

Thanks!

There is a much better choice from Swagelok to convert your stock fuel line to AN fittings. Read about it here in this thread...

I am sure that would work. However, I would think it might deform the stock fuel line to the point it will not allow the o-ring to seal as designed anymore. I was also concerned to be able to go back to stock if needed..........just some thoughts. I also had modified one of the GM safety clips to work with the aftermarket fitting and it did work, but I was concerned if it turned and sprung the plastic clips it would pop off.

Using the Swagelok fitting is a permanent change. You will not be able to re-use the OEM quick connect fitting if you go this route. The first time you smell raw fuel under the hood of your prized toy using any of the quick connect plastic fittings though you will rethink that plan!

Thanks!
Tim, to answer your question. They make a simple piece to remove the Q/D fitting from the line. But you can also take 2 slivers of tubing on each side of the line () and while pushing the fitting toward the firewall, push the () in the fitting and it will release the 4 locking tabs.
If you are interested in a "better" "safer" Q/D fitting that works on the stock line without being permanent. I simply cut off the GM fitting and welded an adapter to it. Now you have the best of both worlds, with a fail safe fitting to boot.
