Quick fuel pump question! Options

[R4R44V15]

Right, so I'm pretty sure I need to replace my fuel pump on my '97 GT. I'd like to just go ahead and get a Walbro, but I don't want to use a universal since I'm afraid the electrical connectors won't match up. Is there a Walbro aside from the universal that will just fit straight away that doesn't require any modification to the existing connection? Or if anybody knows more about the connection there and knows if they are universal as well, let me know. Any info appreciated!

Oh, and one more question while I'm posting... this has only happened a couple times so far, but maybe some of you would know something about it. There have been a couple mornings where I will start my car and it will be very rough, almost "puttering", and fluctuation between right around 800-900rpm. This has happened both when it is really cold outside, and really warm outside, so I don't think the weather is really a factor. Either way, if I give it gas, the rpms go up like normal, but when they fall, the car will die. Though once the car is running like that for a bit, it like... awakens. Haha. Any help or insight on that one?

Thanks so much for the help, all.

have you replaced the fuel filter anytime recently?
also the Idle Air Control IAC could be old/dirty/unplugged
