Odd fuel pressure issue

[Mr Hagg]

90% of the time when I have higher fuel pressure like that its the fuel pressure regulator in the back of fuel pump. Most of the time you will here like a serging sound where relief valve is doing its job and relieving fuel pressure from high pressure rail. THus causing alot of return fuel maybe why you blew the rubber line. Id start there first. ALso note the plug for it is not at the regulator but about 6 inches away on the block...
