Working on this Gen III into 84 SWB swap - getting fuel system sorted out and about to order fittings, etc. I just want to get some more feedback on using rubber Fi hose v. braided line from the sending unit to the C5 filter/regulator. It would make things alot simpler and cheaper but I don't want to have to worry about dryrot or leaks and have to pull the tank again.
Are there a lot of people running FI rubber hose? Even on the sticky threads it goes thru using rubber hose for fuel lines. Safe or not?

Rubber line works fine. Just be sure you use good/hi pressure line that is intended for injection. Another very inexpensive option is the hard plastic/nylon line like the GM cars/tucks come with factory. There are kits you can buy that have all the barbs, quick connects and the tool to install the line over them. Pretty trick.

The rubber will work fine. Just get the good FI hose.
It's a short run, use FI clamps too.

I used Russell Pro Flow braided line and fittings in black the whole run, front to back. It is rated for the pressure and is way easier than working with the stainless braided stuff.

I have the rubber FI hose from the pump to regulator on mine. 3 years 8k miles, so far so good. As others said, make sure you get the good clamps too.

I would use the socketless as a bare minimum, its easy to work with and very durable...

Depending on what out put your engine and pump are producting.. FI rated hose and clamps will work just find... IMO, Many make too much of over killing there systems for show off reasons when FI rated rubber hose and clamps will work just find for there application and driving requirements.

But if your car has racing requirements and high stress safety issues to meet. Then AN and Braided spec'd hose/lines should be used.

I used Aero-Quip Push-Lok hose & fittings on my truck. Have used them for 20 years since they first came out, in all my marine high performance applications, even though the hose is not J-1527 Achohol Rated by the Coast Guard. The only negative is the permeation of gas fumes through the hose when in an enclosed garage. This is one of the reasons why the factory(s) use hardwall tubing of either ridged plastic or metal.
