Injector O Ring dimensions

[Juddder]

Anyone know the dimensions of the O Rings for the Ford Scorpion / Granada Bosch injectors that the Cerbera uses off the top of their head?

I ordered these ones from eBay but as you can see from the photo below they are 'a little' large (at 44.17 x 1.78MM)!



I think they should look like the ones in this picture



Many thanks in advance!

I think you'll find those are the air intake O rings.

Thanks for the replies

The air intake O rings were recommended to me to use for refitting the throttles to ensure a leak free seal to the cylinder head.

Annoyingly I've just put them in the post box to return them, thinking they were the ones for the injectors, so I'll need to go and buy them again!

Thanks for the advice on the Injector O Rings - the nearest they had is 7 x 3mm which gives

Inside Diameter (S): 7mm
Outside Diameter (D): 13mm
Section (S): 3mm
Material: Nitrile
Shore Hardness: 70

[update]

They also had 4mm section ones at bearingshopuk so I've ordered those too

That gives an outside diameter of 15mm

Inside Diameter (S): 7mm
Outside Diameter (D): 15mm
Section (S): 4mm
Material: Nitrile
Shore Hardness: 70

Hi Alex

Did you get the job done and can you recommend which of the fittings worked best ?

Hey Paul

Here's some photos showing the comparison

7 x 3mm on the left (if the writing was the correct way up!)

Existing Injector O-Rings in the middle

7 x 4mm on the right

As you can see 7 x 4mm look much more like the original so would go with them - HTH!
