Doesn't Jim Cathey make shims from the sides of abandoned dishwashers, or some such??
Seriously, though, it is at least interesting to know how it is done. I have not looked around here to see who might do this sort of thing. What sort of pressure is required to test these things? One would think that hydraulic hoses and fittings might be sufficiently strong. Don't know how small one can get though.

If going that route, choose materials carefully. The injector is calibrated by disassembling the injector body and replacing shims of different thickness on the nozzle. I've never bothered to go that route, the testers aren't all that expensive, but finding a supply of shims is another story. my local Bosch injection shop doesn't charge me anything to test them either, so it just hasn't been worth it to invest in the extra equipment. -------Robert R A Bennell wrote: > How difficult is it to do this yourself?
