I do now I'm retarded. I used to see it in the drop down tab now I just have to actually go into my profile. Love the new look of everything!

I don't see the tab for my photo gallery in my profile area with the server update. Am I missing something?

Correct, that's what my JDM harness plugs look like.

No the JDM connectors just differ from the US versions.

Got the OBD1 consult plug wired in and ordered a PLMS USB Adapter with the Nissan Data Scan program. I installed everything on a spare laptop which will just be for the Z now which will have FSM's for the 240z and R34 on it. Extremely happy with how this turned out. It's a great tool to have especially if I attempt the ITB route.

Ok last question hopefully. I ran the new fuel return to the 3/8 vent nipple above the fuel sender. I've got the 1/4" rubber line that was for the original vent hard line running to the unused little fuel return line. My question is what do I do with the 3/8 vent tube I removed from the top of the tank? Does that just need to vent to atmosphere somewhere now?

I cut the vent hard line at the passenger side and still used the old small return nipple on the tank. It got rid of the crazy high pressure but I suppose I should still run it to a larger vent port up top, just not easy to get my hands up in there. I've always used Walbro 255's in my turbo cars. I just know it's a reliable brand, I didn't realize it would cause this domino effect in my fuel system hah.

Ok so I've got the return line plumbed into the vent tube in the engine bay now. My next question is, do you route that back into the same return port on the tank? That nipple is the same small size as the line I just bypassed.

Alright I'll work on using that larger vent line for my return now. Any recommendations on where to run the tank vent line after I do this? I've found a lot of info on this but there's so many different ways people are doing it I'm getting mixed results.

http://forums.hybridz.org/topic/42476-240z-fuel-injection-fuel-line-setup/ Same issue and motor but never heard the outcome. I actually bought this motor for another Z I owned at the time hah. Looks like running the bigger vent line is my best option.

Pretty sure I've got that part right. The return line to the gas can solved the high pressure. There's definitely some good flow returning the fuel back to the tank, it's no wonder that tiny return line isn't up to the task. With the gas returning to the can my vac pressure dropped 5 psi or so..I'm assuming that's normal considering there was zero back pressure on the fpr at that point?

Yeah it's running back through the tiny little return line. Interesting I never heard of running the return through the vent line, the cars efi setup was already installed when I bought the car. With the old pump my FP was always around 43psi which should be 36 iirc. I'll try the gas can test and see what happens.

My fuel gauge is located just before the fuel filter on the feed line.

The motor is an RB25 non turbo. So I was having some performance issues, motor seemed down on power a bit and I was getting some starting problems. I would start the car and it would die, had to blip the throttle to get her going. I suspected the old in line fuel pump needed replacing so I put a new Walbro 255 in as shown here with a pre filter to catch any gas tank debris. Also changed the fuel filter while I was at it. After I did this the fuel pressure was maxed out on the gague. I searched around and heard the rb25's fuel pressure regulators don't do well with a high pressure fuel pump like the Walbro 255 and an adjustable regulator should be fitted. So I bought an afpr and the issue still persists. Turning the fp down does nothing. When I key on the fuel pressure does it's normal thing and it will hold a psi within the normal range but once the car is started it maxes out. The car runs and can be driven this way. I've heard high fp can be a kink or obstruction in the return line but no kinks and what are the odds an obstruction happened right when I changed the pump, I never even touched the return line during this whole process. Any ideas? I'm at a loss here..
