Advice? RR + bowl delete
I've been struggling with high fuel pressure on and off for a while.
Since rebuilding the FPR, trading walbro for stock pump, and using the silver FRX spring a few months back fuel pressure had been a reasonable 65 psi which jumped to and settled at 72 psi a month later. After running a steady 72 psi for a couple months it pegged the gauge at 100 and bowl lid was leaking.
Gauge is working because it shows bleed-down.
New filter changed nothing.
removed bowl, blew compressed air through return line (again), thoroughly cleaned bowl and rebuilt (again)-- no change.
I really don't know what else I can do. The only thing I can figure is either some issue in the return line or problem with the bowl I haven't identified.
I'm at the point where I am ready to throw in the towel and go with a full regulated return system with bowl delete.
Any comments or advise on this move?

a regulated ireturn is very nice and makes your fuel system alot more efficient....it also makes adjusting your fuel pressure easy and adds a place to put a gauge in your truck if you want to monitor as well.....its one of those mods you dont want to spend the money on but when you get it completed and drive the truck youll know it was worth every penny....i run a dieselsite cpr regulated return and bowl delete and love it....i did however switch up from running the 2 micron dahl in front of the stock pump to sticking an aridog 1 in there to lift the fuel to the stock pump....since these pumps like to push and not suck i figured the airdog would feed the pump all it could want instead of making the stock pump suck through a filter and shorten the life of the pump.....on an side note since installing the airdog and sending totally air free fuel up to the engine at cruise speed my truck is extremely wuiet now....my buddy said that if he didnt know my truck was a diesel he would have thought he was riding in a gasser....

~3 months ago I rebuilt the FPR using the kit from dieselorings. After that pressure was fine until it pegged the gauge.
I appreciate all the feedback. I'm going to order the ITP kit today.
Bill you're right, it's one of those things I don't want to spend money on but the time has come. Going with ITP over CPR based on: price, already have intank mods and prepump filter (comes w/ CPR), and prefer second fine filter post-pump. Airdog would be great but is cost-prohibitive for my budget.

I called Strictly Diesel to ask a couple questions and Dennis suggested I disconnect the return line at the front shock to see if pressure dropped due to restriction downstream. This sounded like a good idea so I did it, pressure did not drop. He told me a good way to check the gauge but I went ahead and placed the order. I have multiple indications that the gauge is good:
__checked with another gauge from the other port ~3 months ago
__it shows building pressure as bowl fills
__when pump times-out is shows dropping pressure
__It read 72 psi until spiking to 100 at which time the bowl lid started seeping fuel
