Fuel Lines? Where do they go?

Hi,
I recently had my engine rebuilt last week. I am tryin to put in the motor. I have most everything connected except for the "fuel line"? I have the line with the Red clip hooked up to the fuel rail. But where does the fuel line with the blue clip go? The blue clip has a mounting bracket on the line. Any help? Pictures?

Thanks

There's a thing called workshop manual... you can find it on foxed.ca!

Hmm, that one is on the fuel rail. I think mine are connected their, but there seem to be 1 more on the car itself? So, another blue fuel line? Are there 2?

From my understanding, Its not a fuel line it is an evap line. Goes to the bottom of the upper intake.

One end connects under the UIM (like it shows in Highway8's pic) and the other end will connect to a line above the rear spark plugs, next to the red disconnect.
The mounting bracket holds the fuel and evap line and is bolted to the bottom of the UIM.
I usually keep the bracket off because it can be a pain to remove the two bolts securing the bracket.

Which fuel line needs this. Did I lose all but one or do I only need one. Putting engine back in after a rebuild.

All the fuel lines have the same fitting from the factory. They may differ on color or whether they are 90° elbows or straight, but the connection point is the same.

I don't recognize that one. Looks like it might be from an aftermarket replacement or a random piece of plastic completely unrelated.

Are you missing a fuel fitting?

Some on the connections have this piece, some do not.

I’m thinking it’s the one straight red connection that takes this.

I had one of those come out of my fuel pump quick disconnect... the other ones were missing from the other quick disconnects.

Unhappy part number for the stopper or plastic seal clip

Unfortunately my little plastic basket that goes in the red line got stepped on does anyone know the (part number)? Or do I need to order new fuel line, maybe S2 has upgrade fuel line compared to RX8 S1?

I just ordered a new fuel line. It is slightly different where neither end had that basket. I suspect whatever hose they have now is probably the S2 or 3 and supersedes / replaces the old ones.

From what I understand, the blue clip line should connect to the bottom of the upper intake manifold. But I could be wrong, still learning about these engines myself.

Do the yellow tabs come off the new fuel lines or stay on?
