Hi

I have a FFR fuel tank that has 3 holes in it. The first 2 are straightforward - one for the pump and one for the level sensor, as per the manual.

I am not sure about the third.

My donor is a 2005 Impreza WRX (UK spec, so things may differ to the US). It's a Blob eye. The fuel tank from the Impreza had 2 identical valves/vents in the middle of the tank.

Valves are these I think:

I believe these connect to the charcoal canister, with the 2 hoses joining together with a T piece before that.


Am I right in thinking that the third hole is for one of these valves?

I am a bit puzzled because the hole has no holes for bolts, as if it is some sort of push to fit attachment. The valves were attached to the Impreza fuel tank with 3 bolts/screws.
