Hey guys,
Just helped a buddy drop a new motor in his 03RX-1. Hurricane Motor with Alpine turbo.
Was wondering if it matters which connection off the fuel tank we use for feeding the elec pump & the other is return from fuel regulator.
Buddy didn't mark them when he pulled tank & Im not sure if it makes a difference or not.

We have it hooked up left side fitting feeds fuel pump, right side fitting is return? Ive cycled the pump and we get fuel to the regulator but I want to make sure before firing sled up.

Thanks, guys & Happy New Years!!
 
Is this the Stock RX-1 fuel tank?

If it is you can use any of them.

The Stock setup used two fuel pumps pulling fuel from two nipples Close to each other in the front of the tank.

Also, the old RX-1 did not have any fuel Return because it used the ancient membran type sucktion pumps.
