OK so I just bidded $500 on an R33 GTS4 that no one seems to want. Waiting on a call from the agent to see if I won. 32 GTS4 is for sale. I can't deal with the temptation to mod it. -

Might be there for work later in the year. Wouldn't mind catching up with you fellas - can't have too many beers, but will consume copious amounts of takoyaki while executing an asian squat on the side of the road while you blokes sort out your hangovers. -
I know one example is a anecdote not data, but I'm running the same Aeroflow 525 at full voltage through a regular relay, and while I've had other fuel problems including melting the factory fuel hat, the pump itself has been fine for years. Of course, they aren't *that* expensive these days, you could swap in a new one and see if the issue is resolve. I think you had a previous thread about fuel problems, have you been monitoring and logging fuel pressure? Is there anything voltage related (for example does the voltage go up when the pressure goes down) -

So last night pulling away from the lights, I lost power for about 1 second. Bit weird, but I kept driving... 5 minutes later the pump completely dies. When I tried to start the car, the pump won't even prime. I left the car for about an hour, tried to start it and it all appeared fine. Pump primed, car started, got the fuel pressure I should have.... Start driving home, 5 minutes later it dies again. I'm stuck in a shit spot this time going up hill with a car right behind me, so I just let the car continue to turn over while praying to the fuel pump gods. After about 2 minutes of turning the engine over, the fuel pump came back to life and I got home (only about another 5 min away). So I've been digging around online, it seems like the 525 fuel pumps really don't like to be run at 100% all the time. I've found quite a few examples online of people killing their Walbro 525 pumps within about a year of usage when they are run without PWM. So, my pump is an Aeroflow 525 (AF49-1057) and I've been running it at 100% without PWM. I'm thinking the Aeroflow 525 didn't like being run at 100% and has burnt itself up. I really am sick of dealing with fuel pump issues, my current thoughts are - 1. Use a Walbro 450 and run it without PWM. It seems like these pumps hold up pretty well to being run at 100% all the time. I only make about 350kw and can't see me making any more power any time soon so this is probably a fine option. 2. Get a Walbro 525, run it with PWM. I know doing this will annoy me as I feel like with only 350kw, its extra expense that I don't "need" and I'll be thinking the whole time while setting it up that I should have gone with option 1. I know I'll be happy with this option when its setup and running, its only the initial setup frustration and cost as an issue. 3. Get a Walbro BKS1001 brushless pump. This is the fu*k it I'm already going PWM, might as well go full retard. This option just seems better in every way, with the only downside being cost. But I don't know much about this pump so I could be wrong. Happy to get everyone's thoughts before I go digging around in the fuel tank again.
