I have been doing searching across the board and on reTeds site, about upgrading to SS fuel Lines.

I am still back and forth about doing the parrallel set up, so I would atleast like to redo the stcok setup. Is there a welded fitting that can be welded to the stock hard fuel lines/fuel filter? Or is there any other way to connect the SS lines to the stock fuel hardlines/fuel filter? As well as to the pulsation Dampner ( I got tired of reading about the pros in cons).


Also what is the biggest size injectors you can run in the OEM fuel rails?

 

Also how would you connect it to the pulsation dampner and FPR?

 

banjo bolts.

 

Welding on the thin metal of the fuel filter would be an adventure, to say the least. A TIG setup in good hands might be able to pull it off, though...

Adapters (AN, MS, etc...) of whatever sort you need make more sense...

Are you actually seeing the power levels where the fuel rails would benefit from being routed parallel?

 

I just redid all my fuel lines with -6 SS line. Still using the stock filter, pulsation damper and regulator. Just use some regular hose clamps around the SS line, it will hold fine.

I will be going to -AN fittings with aftermarket regulator, filter over the winter though...

 

Do they make a fitting (like on the brake lines) that you could flare the stock fuel rail hard lines? And use an AN fitting?

 

You can either clamp the -6 SS AN line to the stock metal fuel line - cheap.

Or, replace the whole fuel line system with SS AN lines.

The 2nd is preferred, but it's also the most expensive.

We don't recommended welding anything on the stock metal fuel line.
I believe the metal in the fuel line does not weld well, and trying to weld something is questionable.

WHat about the using a flaring tool? And I guess you would need a NPT to AN adaptor?

 

Flared ends to what?
SS AN stuff has "tube nuts", but they are not designed to be used with steel brake / fuel lines.
There's a reason why steel brake / fuel lines are NOT welded or brazed.

If you're going to insist on metal fuel lines, look at the Russells aluminum fuel lines rated up to 250psi.
Yes, you can use tube nuts with this type of metal line.
And as a bonus, you don't need to flare anything.

What I am trying to do is use the stock metal hard lines on the vac rack and the stock FPR/PD nipples and convert them to hook up SS lines to them. If they are not desined to be used with steel brake/fuel lines then what are they for?

I will look into the russels lines.
