How do I test a GSL-SE fuel pump?

Just as the thread title states...

I'm having power loss issues and want to check the fuel flow...I remember a while ago there was a connector I used to test it...but I've forgotten and I've searched but can't find anything quickly...

Thanks!

here are the details...

https://www.rx7club.com/1st-generation-specific-1979-1985-18/low-idle-power-loss-issue-part-3-a-334886/

a couple of weeks ago i felt a sudden loss in power...

i took the upper intake off and found that i never did put gasket sealer on the upper intake gasket...so i'm going to fix that...i still have to take the fuel rail off just to double check the injectors...

but question...

would an upper intake vacuum leak cause such a loss in power on an SE? if so then maybe i found the cause of the power loss but why all of the sudden? i've done this last winter and now its causing an issue...

oh well...on to the injectors

i'll let you guys know what happens...
