I have not taken mine apart.

These photos were from Cap'n Carageous' and Hurshi's (I think) posts.

Meanwhile, with the EHA off, my car runs well when cold but crappy when warm - severe hesitation on acceleration, smoking badly on hard acceleration, surging idle...

What sort of symptoms do you see on your car which is prompting you to take the FD apart?

By the way, the tech who was supposed to fuel pressure test my car simply diagnosed a "bad FD" without even willing to diagnose further!So I haven't got any results...
