      would you guys know if you could fit a e36 tank on a 1990 e30?
      I've been looking in my area for a tank but I cant find one, and I'm not looking to dish out the 600 bavauto wants....

      I've only called a coupple scrap yards and they dont have one, but I know the E36 tank was plastic so I was thinkin in the long run this would be a better swap...

            Grizzly, I got an e30 tank from Autozone. If I remember right, I paid less than $200, and had it the next day.

              Is an 88 considered a late model tank? Or early? Or its own. My tank is bigger supposedly.

                        is the only downside to this is not being able to run the car on the gas gauge all the way to the E light comes on?

                        how low can you go?

                          Adding a picture of a late model that FrankM e30 and I installed.

                          **NOTE! that the rubber cover does not fit in the opening well at all. It was removed and installed. The red wire is the ground as you can see it was bolted to the old supporting bracket, trace is back to the pump and you will see it is black.

                          The black wire that comes off the pump bracket is the power from the car.

                          **I would cut the feed tube closer to the pump as it is hard to get the level sender to clear the hose clamp.
                          Hose used was 3/8 high pressure gas hose.

                            what is the purpose of the rubber cover?

                            also, I replaced my oe pump with a walbro 255 when it was boosted, and I found absolutely ZERO difference in performance.

                            only replaced to a higher LPH pump if your engine/setup is calling for it otherwise waste of $$ IMO.

                              I think the rubber cover was to keep vibration noise down. But the cover will not clear the turning tabs of the sending top that mounts to the car.

                              My stock pump was failing badly, not to mention it was so loud it came over everything in the cabin. I upgraded because it was only 100.00 and is good to have with my turbo that is happening this year.

                                Exactly and a stock pump from pelican parts is 162 if I remember correctly.
