MFI fuel injector cleaner-ever use one of these?
I got this from a friend who used to work for a Porsche dealer, the fitting is for a MFI injector, anybody ever used one?
I'm wondering what medium is used as a cleaner.... It's been a long time since this one was used, if ever, so the o-rings may be bad but I think it should work with some repairs. Or, is it just intended for testing the spray pattern... Any ideas?   Also have a Kjetronic testor (kinda rough) and an old VW head fixture, probably stick them on ebay

The pressure would have to go higher for MFI. 10 bar is only like 140psi, the MFI injectors dont open until more like 215psi.
The procedure for testing is to hold the injector pressure 1 bar below opening pressure and if no droplets form in 15 seconds, then it is deamed "good". I always wondered, what if it passed that test but the spray pattern sucks? Is that just an aluminum block with a pump etc attached? Paul
