as title states, are all B series fuel pressure regulators the same? they sure as hell look it lol. have 42psi w/o vac which is what a ls should be, need to be in the 50 range w/o vac

forgot i posted this tbh. cars been in the driveway as i slowly do bushings/traction bar. Looking at the link you posted though, its obvious the regulators are different because of the psi, but they seriously all look the same lol. if i recall looking at the last post, my LS fpr was bent, and the current fpr im using is straight down, but its still only 42 w/o vac.

Found my adjustable AEM in the garage so maybe ill swap that on in a few days, might not work though lol

 

They are all bent different i guess thats the only way to identify them
Unless someone knows a different way.
They all have same letters and numbers
Easy way would be to get the blox style fpr and pressure gauge and just set it that way
The diaphragm would be same in all of them its the spring that would be different

 

It that aem has been sitting a while, I would highly recommend getting a new diaphram. My aem split on me and hydrolocked my gsr not to long ago. Oem or aeromotive after that.

 

so you gave up on aem because it sat for long time and diaphragm split up?
