I just installed an aem FPR and it will only hit 20psi(steady) and I tried adjusting the fpr and nothing, only 20psi. Could this be a pump problem or is it the fpr?
Stock fuel pump right now, have a walbro 255 but I want to see if the FPR is working.
 
Its possible the diaphragm in the afpr is is damaged, check for leaks in the vacuum line, and possibly the pump is on its way out, hope this gets you started. Vic
