[QUOTE="Rednaxs60, post: 228512, member: 4617"] Another notch in the belt. Tested the diaphragm fuel pressure regulating valves, OEM original on right, and Delphi FP10490-20822 3 BAR. Had the Delphi return connection straightened to fit: [ATTACH alt="FPR Valves.JPG"]49418[/ATTACH] Used a scientific apparatus, water in the hose - connected the compressor, used the compressor pressure gauge to determine FPR valve relief pressure: [ATTACH alt="FPR Test Rig 1.JPG"]49419[/ATTACH] The OEM original FPR valve held up to approximately 37 PSI, not bad for the age. The Delphi only made it to 30 PSI. Connected the adjustable fuel pressure relief valve to the test rig: [ATTACH alt="FPR Test Rig 2.JPG"]49420[/ATTACH] Adjusted this FPR valve to approximately 43 PSI. Flows well when adjusted pressure is exceeded. Install space is limited but install will be done. [/QUOTE]
