Cannot pour in fuel additive

[Denzil]

Hi guys

I've got archoil fuel additive that i want to use, but when i try to put the nozzle into the fuel tank, the black plastic flap will not open.

I've even tried a funnel with a different sized nozzle, but still no joy. However i never have a problem with the flap when filling up with fuel.

Any ideas on what is preventing it from opening?

Cheers

Must have an anti-syphon system on it. For safety so nobody nicks your fuel

Hi guys

It looks like I'll need a tube or funnel that has a 25mm diameter which is the same as a UK diesel nozzle.

Can I just ask why the additive? Unless your car is spitting plumes and is generally very unhealthy, I’ve always taken fuel additives as a last resort?

If your feeling slightly bogged down. Maybe an Italian tune up is in order?

If you are sure you will not try to fill her with unleaded - take out the miss fueling device.
Takes about a minute - simple enough to refit if you really want it back in.

Instead of using an additive use premium fuel like V-power it has all the additives and cleaning agents you'll ever need.
