Working on an LS swap and having lots of fuel line issues. I connected a LS style regulator up the same way the stock bmw filter was labeled. It has an in from the fuel pump and what I’m assuming is the return to the tank line. The first LS regulator I tried was a cheap Evil Energy brand and on first crank, it blew the line off and it was trashed. Second one I tried held together and the car ran ok. Fast forward, I get a fuel pressure sensor and it’s reading high, like 80psi. A few days later and the rubber line on the inlet to the filter ruptured. Has anyone dealt with this? Am I plumbing it wrong? ChatGTP is saying check the return line for obstructions or blockages.
