I recently got a used AEM fuel rail, picked it up for my setup. Now to the problem...

I'm going to be running a Aeromotive FPR seperate from the rail, how do you plug the hole where the factory regulator hooks up the rail? Is there some sort of threaded plug for it? If so, does anyone know the thread size and/or pitch of the plug?

Also what is a good size to run for fuel line to the regulator from the rail? Inside diameter.

Thanks for any help.

 

Well I've put one of these on my friend's turbo car and if I remember correctly we ran a line from the regulator to that spot on the rail so it wasn't plugged there was just a line between the regulator and the rail. I don't know the thread size because we had a fitting that was the right size with us already.

Just take it to home depot and see what fits the hole in the rail. This was on a turbo gsr (stock motor) and we used 1/4" barbed fittings I think.

Don't know if any of that helps, just letting you know that we didn't plug the hole, we used it.

 

That's kind of what I was thinking. I assume it might be 1/8 NPT, I might just try and call AEM's tech support and ask them directly.

 

Get a golden eagle Fuel rail, then ucan put a plug in it and run it off the toehr side of the rail........Like me!
