Got my two new fuel pumps and installed them - was surprised to see no gaskets between them and the engine block - unless they BOTH fell out and I cannot see them where they lie - unlikely. My Clymer manual says there are gaskets and to replace them when replacing pumps.<br /><br />But the parts explosion on the "parts" section of this web site (from whence I ordered the pumps) shows no gaskets.<br /><br />What gives. Don't those run on manifold vacuum or whatever and they need to be airtight?<br /><br />Engine does run fine with new pumps mounted metal to metal, so I'm completely confused.
