....Now what do I do with this aeromotive filter I bought.. No point in using two filters
Well I decided I will update the PDF. For the filter delete section I only mention that it shouldnt be done unless you are adding an external filter. I did not mention that it requires a return fuel conversion if you do it. I underestimated what people will try and do I had not figured anyone would fit an external filter inline an otherwise stock returnless system. I wish I had not overlooked that possibility, as it might have saved you some trouble.

Good thing Phunk came in for the rescue! Just get the the return fuel system, you'll want it eventually anyway and you already have the pump
you did call it, that it was flooded.

The G37 version of the pump is several inches shorter. You will need to use your 370z stainless hat rods, and you will need to carry over your 370z level sensor riser (the black plastic spacer that it mounts on).

Otherwise, you are good to go with the G37 version of the pump. So long as you didnt get an early G37 pump which is actually a 350z pump, which would leave you in bad shape.

It looks identical to the 370z pump assemblies from the pictures, I only planned on using the filter basket from it.

And yeah sorry, my thinking was yeah sure why not cut the internal filter out and add an external? Wouldn’t hurt if I ever needed to change the filter out! Didn’t think about the regulator being affected lol

Running a return system from Charles for a while and have the external filter with the top hat store at home with the dilemma of whether to ask Charles for the dual pump assembly or do what the op did and look for a stinking use stock fuel pump assembly and ask Charles if i can send it to him for the filter delete and upgrade to a 450 pump since for some odd reason my shop doesn't want to do the modification. Yeah don't ask me why guess they are afraid they might **** things up.

Sounds like you’re going to have to pull it all out again and find out what was not setup correctly. If you want you can ship it to me and I can set it up for you for $85 plus return shipping.

Wow well that’s sort of good to hear but I would recommend taking it out and rebuilding it again. It should fire right up and start and run perfectly as if the car was factory stock and brand new.

It does now, I believe it may of been flooded at first. When it finally started it shot smoke everywhere, now it runs like normal. Just needs a re-tune to adjust for the bigger pump.
