Default 91 ucf10 air line bypass

So i got to thinking while continuing the troubleshooting on my non-op air suspension woes. Cant i put together a manual dump/fill line that bypasses all the factory stuff or a setup that uses the main feed lines for the entire system?

So what i need to know is:
-What size is the tubing/lines running to the bags are.
-if i reuse the main lines, couldnt i just add a t fitting to tie the front/rear bags together then add a line with a schrader valve (think tire valve stem) to inflate/deflate the system. This option would remove the factory air pump
-where could i get a simple valve for quicker delfation of the system?

Thoughts, tips or ideas folks?

technically yes you can do that but without a fill tank you will need to fill each bag depending on how you plumb it all. this is also assuming your bags are not leaking, when most factory air suspension bags do at this time and age! what is broken on your air suspension now?

the tubing on factory air suspension is 1/4" hardline, like the brakelines, with flare fittings. you will need to know how to work with hardlines, cut and/or tap and flare them, in order for your idea to work.
