Send those injectors off to Witchhunter, but I would still advise to get some fresh gas in there otherwise you might gunk them up in a short time. Are you planning on upgrading the fuel pump? Might be a good time if you don't know the history of the one that's fitted. Either way replace the fuel filter, clean out the fuel pump with some fresh gas, and drain your tank to half way while you are there. Then add some fresh gas to top-up and you should be good.

 

Thanx

 

another souped up black 951 out there to look out for ....

 

 

I'm thinking these injectors are probably high impedence and wouldn't fire. I'm going to send them off for testing, but I think I'll pick up a set of low impedence Seimens from Racetronix. Thanx everyone for your help!
