03 Blazer engine code X Fuel pressure falling off after prime, Long story short after getting just about back together did another check, new regulator in can't tell how high as it falls off too quick after prime to tell. Leak is under the spider body near the regulator. Would this be where the nut kit would come into play? It is the newer assy. with the injectors in the LIM so would I need the whole spider assy. instead?

 

went and bought a new spider today and got it in, pressure now holds as it should, need some more daylight to finish. The old injectors were a lot of fun to get out.
