fuel pump
are you sure the fuel pump is turning on ?,there should be a place on the motor to check fuel pressure,but make sure the pump is turning on,also there is a shut off for the fuel pump in cse its been rolled over or a big bump might set it off,i have forgot before to plug the wires back in after i changed a fuel pump once,,?.

Yes I can hear the fuel pump amd relay when I turn the key. I did push on the schrader valve but nothing came out....so definitely a pressure issue but I'm confused as to where the pressure issue is. I used a flashlight and looked best I could at the fuel pump and do not see any leak. No leak at the filter either. So.....???? IDK.... lost....

Since your '98 does not have the fuel filter internal to the fuel tank, the next thing I'd suggest you try is to disconnect the fuel line input to the fuel filter, connect a hose to guide any fuel spray in to a container, then turn the key to the Run position a time or two to see if fuel makes it to the fuel filter. Also pay attention to what the fuel looks like that might drip out of the fuel filter. There's a chance your fuel filter is plugged. If it is though, you may want to drop your fuel tank and clean it out as well since the input sock on the fuel pump is likely similarly restricted and the tank probably needs a good cleaning.

Is there anyway to rule out the regulator? Its the only thing I didn't replace that I can think of. I had tested the fuel pump by switching it on and catching the fuel before I connected the line to the filter so I don't think that is the problem.... I suppose something could have got stuck in there after I connected the hose to the filter but I don't think thats likely. To me it would have to be something after the fuel filter causing it which makes me wonder if it's the regulator?

If the fuel pump is working properly, the fuel should come out the line before and after the fuel filter with a lot of pressure. If you didn't check before and after the filter, or it was more of a stream than a pressurized flow, you might still be looking at an issue with the fuel pump. The good news is since you recently had the fittings free from the filter, it shouldn't be nearly as bad to get them apart now.
