[TR] TR3 fuel pump

[KingsCreekTrees at aol.com]

Hi;
 
I have an early TR3A. I've just replaced the fuel pump with a Moss Motors  
unit. When off the car, the pump sucks and blows (if you'll pardon the  
expression) just fine with the primer. However, once bolted to the car, after a  
couple of pulls up on the primer lever, there is no more resistance on the lever  
and no more priming. When I then remove the pump, suddenly there is resistance  
on the lever and you can feel air blowing/sucking.
 
I am sure there are no leaks in the fuel line, incidentally.
 
Any ideas what I should do next? Am I installing it wrong?
 
Thanks;
 
Tim
