I had some similar questions helping a friend put an LS engine into an S10. In his case we found a fuel rail and came up with a way to change the upper part of the regulator. As I remember there is no access to the Vette regulator in the filter combination assy.

What did Merc originally do for regulator? This seems to suggest they used an external part.

Does the damper look anything like a regulator? I've has some success taking regulators apart and putting them back together using special clamps. Hard to see but this regulator has one of these clamps holding the halves together.


I have built special fittings to install these regulators in places where they were not originally found. Here's one on a smallblock marine intake:


The steel sleeve fitting was made on a drill press. The regulator, a stock part from a Cavalier 2.2, can be rotated to any position.
