i refitted my bosch 040 in my 33 after the guy owned it before me sta it in the factory position so i could use a full tank of fuel and get rid of fuel surging round corners, was a good write and showed me where to position the pump correctly to get the most out of it without the noisy pump issue
just becarefull as i had mine suck up a pump full of sedement and had to pull the tank out to clean it, this is not a fun job on a R33 at all.
