In tank fuel pump conversion

Post by Fred_L-P » 25 Nov 2018 16:28

Since I'm rebuilding the whole car I figured it is the perfect time to upgrade the fuel system with an in tank pump.

So far the 2 best options I found are the PA-2 kit from Tanks Inc or the Phantom stealth from Aeromotive.

I'd like some feedback from people who used these or if you have any other suggestions.

Thanks guys!

Sorry if it's been covered, but I can't find any thread on the subject.

From one of my previous build threads:

Fuel System

Since the SR20DE is a fuel injected engine, we would need an EFI rated fuel pump and lines to support the system. I really like in-tank fuel pumps, and many times we will do a 300ZX in-tank fuel pump conversion into the stock 510 fuel tank. But this project threw a wrench in the works as it had a beautifully painted gas tank in the car.

Image

I certainly did not want to have to repaint a fuel tank, and I had been reading about a very interesting new in-tank fuel pump that is a bolt in made by Aeromotive. https://www.aeromotiveinc.com/product/p ... el-system/

The Phantom 200 Stealth Fuel system is a bolt in system that has a foam catch can, and can be installed into a 510 fuel tank in about an hour. Here's how we did it.

The 510 fuel tank is divided into 3-sections-- one section where the fuel enters the tank, the center section (where the fuel sender lives) and the third baffled section to the left. We put the in-tank fuel pumps into that section as it does no interfere with anything else.

A word of caution here-- modifying and welding fuel tanks can be VERY DANGEROUS be sure to clean out the tank as much as possible and let the tank vent as long as possible before attempting any modifications-- if you are not comfortable with this kind of work, then leave it to the experts.

A location hole was drilled into the top of the tank-- basically centering the pump on the level portion on the top of the tank:

Image

The tank was then taped up with painters tape to prevent any scratches and the appropriate sized hole saw was used to cut the top skin of the tank:
Cut slowly and use a sharp hole saw and the procedure is pretty easy.

Image

Once that is cut, you will need to use some shears to cut away the internal baffle (it is T shaped).

Aeropmotive provides a drill jig to accurately drill the 10 holes in the top of the tank for the mounting ring:

Image

Then the C-shaped mounting ring can be installed into the pump:

Image

The mounting JIG is then reinstalled so you can install the foam "catch-can" which must be cut down to the height of the fuel tank:

Image

Since it is foam, you can squeeze it together and slide it thru the JIG and down into the tank-- it then expands into the inside of the tank:

Image

Image

The fuel pump assembly was then shortened to match the height of the stock 510 tank:

Image

The foam sealing ring was then installed, and then the fuel pump, and the assembly was tightened down making a fuel-proof seal:

Image

And installed in the car:

The Phantom 200 Stealth Fuel system
In your opinion, is it worth the price tag? For us it's more than 700 CAD$. It's the only reason I was leaning towards the Tanks Inc solution since it's half the price.

I have put in several of these systems with no issues-- they work great. The only possible thing that I would be concerned about is the eventual breakdown of the foam baffle-- and the Tanksinc. version has a steel catch can and steel construction instead of the billet aluminum that the Phantom has.

Is it worth twice the price? Not sure. They are a quality piece, there is no doubt about it when you hold them in your hand...

Looking forward to seeing what you decide to do.

That Tanksinc. setup seems pretty awesome. It even comes with a fuel pump unlike the Aeromotive unit. I'd be inclined to try it and I might go that route if I find an issue with my Z31 setup.

The Aeromotive Phantom unit comes with a pump-- and they have several sizes depending on the application needs (ie. turbo engine):

That's pretty much the reason why I went with the PA2 kit Fred.

I'm happy with the results, pics are in my build thread: http://www.the510realm.com/viewtopic.ph ... 70#p264905

I decided to go with the Tanks Inc kit.

I should do the work shortly, I'll update with the result.

"slow clap" to Summit for all the unnecessary packaging. This is insane
