SB,

Noted. I'll have to dig it up, but I'm fairly certain that is how it was described on the receipt. All good.

is what is going back in during rebuild.

Thanks. Brad.

Guys,

So, I'm chewing on this, viewing this as a potential solution for others down the road, and need a consensus....

What size fuel inlet -AN fittings, and what size return -AN fittings? Maybe two different setups for NA and boosted? These decisions are NOT in my wheelhouse....

Thanks. Brad.

8-AN fitting

Rookie,

Inlet? Outlet? Both?

NA? Boosted? Both?

Thanks. Brad.

Both

Should support 800+HP. And at that power level if someone is asking fuel line size they probably shouldn't be rigging a 1000HP engine.

Rookie,

Fair enough point. To be fair, I won’t be doing the rigging. I’m just building a fuel rail for what is going to be rigged. I’m also thinking down-road for others that may be looking for a replacement fuel rail

Not to nitpick, but would this be for each rail, or a single line before splitting to the two separate rails? What I’m building is a PAIR of rails, that will be plumbed together by Ys or Ts. What I’m looking for is what should be at the end of each rail, incoming and returns.

Thanks. Brad.

You could just tap the ends of the fuel rails to 3/8 pipe and the installer can use whatever size AN fittings that he wants.

There was a lot of discussion in my EFI thread about Y's and T's and they talked me out of them. This is what I ended up with. Probably wont work for your application.
I'd stick with -8.

would probably be better to cut them for an O-ring fitting as the pipe thread could split the aluminum rail as the ends would not be very thick. I am not a machinest so that is just a guess.

Shouldn't the return line be sized bigger than the feed line?
