Two type 44 questions

[Hale, Duane A WRAMC-Wash DC]

Problem #1 - Replaced the 'check valve' on the fuel pump but it didn't solve
the stalling at idle (primarily when the car is warm) problem.  Any other
guesses as to the culprit?  It does it when coming off throttle, as in
pulling up to a stoplight/sign.  Really annoying, and it takes about a
minute before it will restart.

Problem #2 - any quick tips on replacing the right (Passenger) motor mount?


Thanks!
