You have to look how many turns are on the worm of the pump. How many turns have you got as paint not an accurate indicator

350 has yellow blob of paint on one of the housing screws, 250 has red blob. Bit of a mix regarding 4L1 markings some 350's did have it some did'nt.
Maybe Arrow pump expert will come along and put you right.

Leave the pump on for now dude. As its a power valve its much more unlikely to have a 250 pump on it. Have a look at my "A word of warning" thread in the tech section. This should put your mind at rest.
