Starting problem

[SeKcGamer]

Interesting thing I found while working on here for an hour before I go to work[emoji849]. This filter that we replaced had a tiny black filter and this new one hasn't even been touched by fuel. Interesting...

I think that you have too many filters back there.  The EFI pumps are high volume "pusher" pumps, they don't like inlet restrictions.  And they'll pass a lot of junk.  People like to put the prefilters on (no offense to you guys that do) but they make the pump work harder.  Can't tell from you pictures for sure, but it looks like you have a filter before the pump, then a smaller glass one after the pump.  Then of course there's a big EFI filter in the engine bay.

If it was mine I would remove all of the filters in the back by the tank, especially because you've cleaned and coated the tank.  There should not be anything to filter out before the pump, unless you're buying dirty fuel.  Set the system up just like Nissan did, they had a very coarse sock filter inside the tank and that's it.  I've been running mine that way for about 60,000 miles, and my tank is not coated, and it has rust on the filler tube.  The pump has been on for those same 60,000 miles and it sounds fantastic.  I can't hear it.

Dropped the tank. And all I really see is that that one filter is untouched.

No fuel passes through there

Does the tank need to be full? Because trying to trace those lines, and it looks like it leads to this one small line.

I only have two filters back here.

It takes some air for me to blow through those.

That's two too many.  You could bypass them just for a short test.  Then you'll know something.  Also, if you're careful, you can connect up your pump and lines and put some fuel in the tank and let it run.  Don't let the battery spark.

Not really clear what you're doing now.  Is the tank out, or are those old pictures?  What is your plan?  Gotta have a plan.

You can run a wire through those ports.  The return line should be open, the inlet will have the sock on the end.
