Fuel Pressure Regulators

I have a 2001 Jimmy 125,000 miles - Replaced original Fuel pump, Spider ,and fuel filter. After 3 months of running great , the Fuel Pressure Regulator failed . Installed new one and it lasted about three days. Now I'm going on the fourth one . They only last a few days then the diaphragm ruptures.

Has anyone had this trouble ? If so what was a solution ?

I"m new to the forum ,so go easy on me

UP DATE : I just installed another new FPR I hooked up the lines and checked the pressure to see if the new one leaked. Everything looked OK . I relieved the pressure at the test gage . When I removed the fuel lines to begin putting the plenum on a little gas ran out of the large fuel line (this would be normal since the line in vertical and a little gas would be in it)

When I removed the small fuel line it had pressure on it and squirted gas out .

Is this normal ?

Any help would be appreciated !!
Best Regards !!

No build up of pressure in the tank and all plumbing looks ok I went to AZ this morning and they gave a store card for the cost of the Sorenson FPR. I just didn't want to put another one back in. . So I left and picked up a BW brand and just got it installed ,changed oil . The Jimmy runs fine. I may have trouble but I have to say the quality of the BW looks better than the Sorenson. I 've not had a leak around the seal but the BW seal looks so much better and some of it is brass.
