Just put my modified 4x4 (i think) fuel rail, with aeroquip fittings welded on, onto my new ST escort inlet with rochester 1000cc injectors and i get a fair bit of movement in and out of the rail/head, not enough to reveal the o ring either end but too enough to worry me slightly
ive read a thread from a while back with people saying this was a problem with some billet rails but this is all OE stuff apart from the injectors
also did the 2wd or 4x4 rails have injector clips? as the ST fuel rail i have taken off (i want to keep the aeroquip fittings) used proper clips to keep them secure.
Thanks.
