Ok so I pulled the tank fuse and drove it for a bit on just the main pump. And put the in tank fuse back in. Now seems to be running well again. May have been some sort of vapor lock in the pump that has now cleared.

OK so when i pull the in tank pump fuse the car runs better, but you can tell there is a load on the main pump. But when i pull the main pump fuse the main pump continues to run. Could this be the source of my issues? And what does that mean?

I've checked and the pump is installed correctly according to http://www.cleanflametrap.com/transferPump.htm and there is still an issue. The install guide says to check the polarity of the electrical system. How do I check that? And where?

it was the same model pump and there was only one way to wire the pump in. Is there a way to check if it is pumping the proper direction?

The car has been idling rough for a bit, then two days ago it died after a mile down the road. It seemed like it ran out of gas. I decided to replace the fuel pump relay and the in tank fuel pump. Successfully replaced each and the issue was not resolved. It'll turn over just fine, then about 30 sec...
