Mid to hi 12s AF at WOT in the higher RPMs. The unit learned and leaned it out, and by the third run it looked pretty good. Took the car out for a quick runs tonight. Seem to seal great and don't try to squeeze out when you tighten the sender or pump down like the neoprene ones. Didn't want to wait so I bought some cork gasket material and made my own. Thanks for the suggestion on the cork gaskets rel3rd. As soon as I started driving the needle moved up near full. I checked it with a meter after install and all was good so I had no idea what could be wrong. Had a scare when I put gas back in it.I knew I put at least 15 gallons in but the gauge only read 1/8 tank. The universal sender from Tanks was ok, but i think if I was to do it again I would buy nice tube type I found. I contemplated using the stock 1/4 return line that was originally used for the carb, but everything I found online said this was a bad idea. I decided to do as others have done and use my stock 3/8 line as the feed and then ran a new 3/8 return line back to the tank. I had to get a little creative to plumb in the nitrous fuel solenoid, but nothing a few fittings from Home Depot couldn't fix. I did add an AN fitting to the supply line to make a nice leak free attachment that is easy to disassemble in the future if needed: I went for a long drive today - no problems. I disconnected from the factory vent line and installed the roll over valve supplied by tanks inc. I figured out that the tank was not venting enough. After a few minutes, car would start and run again, then stall again after a few miles. ***edit 4/20***took the car on the first long drive yesterday. Unfortunately I forgot to take any pictures of the venting set up. I capped the other two driver and passenger side stock lines off. I hooked into the middle line on the car from the supplied T fitting from the tank that connects to the tank and pump. I elected to use the factory vent system rather than the roll over valve. The only details on our cars would be the venting system. Rather than show you the pics this time, Reference the camaro site that has great pics and details: This is also with 28" tall drag radials and 3.08 gears.Car's been with 4.10's, so I'm 100% sure it'll go 11.20's as is, with a gear swap, but am getting used to the 3.08's.I must really be getting old.lol. Well weather was better on the carburetored runs, and I usually have a half tank of gas, but it was full the other day.Īlso the WOT AFR was actually very rich, like mid 11:1 rich, which I think is because the ECM "learned" WOT with the lame FiTech Fuel Command Center, and kept dumping fuel, trying to compensate for no fuel being there, and now that the supply issue is fixed once and for all, it's needing and trying to learn around that.At least that's my theory, lol. Ran 1 mph faster than ever, and a couple hundredths quicker. I actually went to the dragstrip finally, on Wednesday evening. The tank, pump and sending unit all look and work very well though. I'm not happy I'll have to pull the tank down again in the near future.especially since the straps they supplied are very flimsy, soft metal and bent up on the ends when tightened. I'd also HIGHLY recommend using their CORK GASKETS for the sending unit and pump.I did everything exactly as they said to, even searching for and finding Indian Head Shellac sealer, and 1st fill up, they both weeped a little gas. I also have a vented cap, as I definitely did not want any more venting issues.lol. I didn't want to risk using the 1/4" vapor/return line, so ran a completely new EFI rated rubber 3/8" return, and used the factory 3/8" steel line as my feed. I have it looping up over the driver's side of the tank, and secured up behind the rollpan or whatever it's called. I also had the 3 vent lines on my stock tank, but chose to use their 2 into 1 vent system.
