Had fuel injector quit on my 88 GL wagon EA82 SPFI.  Have a donor throttle body from a previously running EA82 (buddy replaced with EJ22 swap).

 

Everything cleaned, ready to install the donor throttle body.  Went to apply the new rubber gasket/seal (from NAPA, could this be the problem?) to the channels in the underside of the base only to discover the seal seems to be too small.  When I get one side in place and work my way around the perimeter to the opposite side, it pulls the first side out.

 

Is there a trick to installing these rubber seals like applying some sort of substance (whatever that might be) to make it expand a bit?  I know when installing an oil pump seal, it must be installed dry since it expands once the oil contacts it.  Does the throttle body seal require a different approach?

 

Or is this simply a defective seal and I should find a different brand?

 

Use a dab of ultra grey to hold it in place.

Hey thanks, MilesFox. I used some ultra grey along with a few spots of High Tack sealant and the gasket remained in place. Throttle body is bolted on.
