Splicing gas lines

[NHCharger]

I should have looked better at my fuel lines before welding in my new sub frame connectors. I need to replace the front to rear fuel line.  The sub frame connector has a slot in the front where the line goes but I can't snake the line thru two consecutive 90 degree bends.
Is there any problem with cutting the fuel line and using a connection in one spot?

Of course the best way is to have one solid line.  But if you must splice, I would suggest AN fittings, or even barbed AN fittings.

use a double flare connection

DO NOT USE SLIP ON COMPRESSION FITTINGS
