[TR] TR3 fuel pump

[dave1massey at cs.com]

 Have you tried it with the fuel line disconnected at the carburetor to verify fuel flow?? It is normal for the fuel pump to stop "working" once fuel pressure is reached.? You may have an obstruction in the fuel system so check that out, too.

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?
