Alright guys, here's my issue... 3x2 setup with freshly rebuilt Stromberg 97's on a sbc. Summit electric fuel pump with a Holley low pressure regulator with a Mooneyes pressure gauge off of the open port on the regulator. Have about 400 miles on the setup with it running flawlessly then one day it starts running a little funny for a few runs then all of a sudden there is fuel GUSHING out of the top of the primary carb. I messed around with the regulator a bit and could never get it fixed so it sat in the garage for a week or so. Go back out today, car fires right up, check pressure and its set right at 2 psi. Drove the car for a few miles and it seemed to run ok, checked the fuel pressure gauge again and it seemed to drop pressure on its own to 1 psi and then 0 psi a few minutes later according to the gauge. Drove home and tried messing with the pressure but could never get it to show any pressure on the gauge but car was still running. Then once again fuel starts gushing out of the top of the primary carb (look at attached picture to see where from) and car will not run. If I turn the pressure down SUPER low the car will run for 30 seconds or so but then die I'm guessing due to lack of fuel, but then if you turn pressure back up to 2 psi or so it starts gushing fuel again. Any ideas on what's going on? It's obvious that the issue has something to do with fuel pressure but what could the issue be? Any ideas would be much appreciated. Thanks.
