I tried a single 3.125" ID x 5mm in the housing but it was too thick so will try a 3.125" x 1/8" next time. |

Mine's not leaking but I'm looking for an appropriate replacement for the seal in the housing. Loose o-rings on the throttle body don't enthuse me. |

Great work. I ended up replacing the hose, the throttle body, the donut hoses and the other pipe with the fragile plastic connector to resolve my intermittent restricted performance. However, when the seal starts to go on the throttle body connector, as it surely will, I’ll do this mod.

Just to add that I recommend the gas specification PTFE tape as a diagnostic step or temporary repair only (considering it costs 50p and you can get some in any hardware store), to confirm if the seal is causing a restricted performance problem or hold out until you can obtain a new part, not as a permanent repair.

Did mine with 0 rings and PTFE as it was leaking a bit. Pretty sure it's made an improvement to drivability and the harsh 1-2 shift is now not noticable. Cant remember how many rings I used but it took considerable force to get the retaining ring to engage and it then became solidly fixed. 2012 TDV8 Vogue (L322) |

Me also, ten 75mm x 3mm O rings for £5.50 on eBay, so I’ll have spares.

Just completed this and now have a movement free joint between the plastic intake and throttle body so assume it’ll be leak free, but I’ll check for any oily mess escaping after a few journeys.
