Aye,
I did, but would opt for a thinner walled version next time round.
Got 4mm ID x 7mm OD for the smaller connectors and 5mm x 8mm for the larger ones.

Photograph below is 4mm x 7mm on one of the larger bullet connectors.
Might try 4mm x 6mm for both sizes next time, but that could be a while, which would also help see how it stands up to conditions in an engine bay...

If its silicon then it should last for ever. I'm replacing my original Citroen ones with Silicon as they expire. I hate spade terminals.
