RV8 3.5 injector hoses

[Steve_D]

Early RV8s had fuel injectors with a short length of hose to join to the fuel rail.
The top of the hose (onto the rail) is secured with a hose clamp but the bottom (onto the injector) looks to have nothing securing it just a metal ring that looks to be just a trim for the end of the hose.

So, is there anything securing the hose and can I replace them as they are pretty old?

Splendid info there thanks very much.
As an update for others I tried replacing a hose today and found that unlike the Jag injectors that have a plastic barbed fitting where the hose fits the RV8 ones are ali which means you do not have to be quite as careful not to cut or damage plastic when trying to remove the old hose. Whilst doing this I found particles of probably dried fuel etc in the top of the injector which is not good plus it takes quite a time to carefully remove the old hose so as a business it is not cost effective. That injector company will clean,service, test and replace the hoses for £16.80 each so that is what we will advise the customer.

Thanks again
Steve
