breakaway separation no drive off or external force

[RLKNIGHT]

We have a site where a 3/4 HP Red Jacket STP supplies fuel to a Wayne Select S1 Compact dispenser. The site is claiming that the breakaways, 2 different manufacturers and 2 different styles , are separating. Separation is not due to drive off, site rep claims he witnessed the breakaway ( OPW 66V-1300 single use) separate while the dispenser was not in use. Has anyone else encountered this issue? breakaways were Catlow single use, OPW reconnectable, and OPW single use.

Our company uses this type of set-up frequently. I'm not sure what's happening, but I have few questions for you to help diagnose the issue-
1. does the S1 select have the hose mast option ? 2. what is the overall length of the hose assembly? 3. Is there a whip hose in the hose assembly?

set up is Wayne dispenser on stand mounted beside Convault tank> pipe run from STP to dispenser is under 10' > 1" ID elbow from dispenser outlet to filter housing > 1" ID elbow > 1" x 12' steel flex curb hose> breakaway> 8" whip> 1" (2) plane swivel>reducer bushing OPW 11B-0100 Nozzle. There is a PEMCO retractor utilized approximately 5' from the filter housing to keep hose off the ground. Don't have photos saved online so cannot provide a link.

you just might have a pressure relief issue.

Red Jacket pump.

If Red Jacket adjust line hold pressure at functional element (if newer style), screw out pressure less screw in more pressure.

A first on the forum where two modorators comment.

Agree with Zane, it could be a pressure issue. I am also wondering if there is too much tension on the hose from the hose retractor assembly.
I found an old manual here's a link with instructions on how to adjust the tension if that is part of the issue https://www.dropbox.com/s/5iec4lq6zirpm ... 9.pdf?dl=0

I wonder how the pressure is getting through the pump or dispenser to the actual hose? sounds like a breached solonoid valve could be a piece of this issue

Ive had that issue on some old Tok's that had check valves with fouled pressure relief's installed inline after the meter. Swapped those out with new and no more issues.

Thank you to all. Zero tension on hose, will pass along these recommendations sorry for delay in reply was on vacation.....

03-17-2023 Update: tech put gauge. on line prior to dispenser and after dispenser prior to filter housing presures while dispensing fuel, line pressure is 28-30 on line both prior to the dispenser and after the dispenser. Stop fueling return nozzle to cradle(STP stops) line pressure prior to dispenser meter drops to zero while line pressure exterior of dispenser prior to fuel filter housing climbs to above 50 PSI. This is without reenergizing dispenser or STP. installed a T in line and ran copper line back to Tank port of STP. line pressure drops to zero. Tech believes issue may lie with proportioning valve/ solenoid interior to Wayne dispenser...... any input?
