and it should pull down to nearly the bump stop (depending whether it has any air leaks or a aftermarket dump valve etc) when running at idle or on the overrun.
ok thanks mate
it does sit on 0 when the engine is off,and it sit's on the bump stop
when car is on tick over,it does not have any aftermarket dump valve
and i have just fitted a brand new t28 not a recon,the problem is it seems
to have developed a surge when driving and the needle seems to take
a lot longer to climb up the gauge.......
