i want to clean and tart up the outside of my metering unit, and was wondering, if i take the main top cover part off, is anything going to be spring out at me, or is there nothing inside there really?

i know i will need a new gasket, which i will check with fords first to make sure they still have them.

if i do this tho, am i likely to fook something up? or is it prity straight forward??
