Cool JDL Mfg In-Tank Surge Tank for Mazda RX-8 - Modified Motorsport Bulk Heads

Category: Engine - Intake/Fuel
Price: $520
Private or Vendor Listing: Private Listing
Part Fits (you may select multiples): Series I, Series II
Location (US State/Canada/Int): OH
Item Condition: Used

Selling my JDL Manufacturing surge tank for sitting inside of the Mazda RX-8 fuel tank. No fuel pumps included. Includes Fuelab Bulk Heads, and venturi for pulling fuel from both saddles of the tank. Never used, just modified and put back in the box.

If you're looking for a track solution or mild boost setup without fuel starving this would be a great setup. Also not shown is a venturi fitting so you can make the lift pump pull fuel from both saddles of the gas tank.

I modified it to fit dual brushless fuel lab pumps with their bulk heads. As such, 4 of the electrical studs for the pumps were removed, and two 3-wire bulk heads were added. In all, the 2 remaining studs can be used for the fuel level float, and the 2x bulk heads (x6 wires) can be used for up to 3 brushed pumps. If you want to run dual brushless pumps I have a second bulk head I was going to use for the level float. Just let me know I can add that in.

The Bulk heads installed can serve for two benefits: Using a brushless pump, or keeping a cleaner install with brushed pumps, plus extra wires for lift pump or fuel level float. Extremely nice units. IMO this provides a more robust, motorsport style wiring solution vs the studs.

If you need help wiring I am happy to help.

I am moving to a larger external surge tank, as I believe my specific setup will be too large for this.

Any questions please ask. Like new never installed, but modified.

Asking price is shipped. I ask the buyer to either cover PP fees.

Payments, I accept Zelle, Cashapp, Venmo, or Paypal; any protection fees I ask the buyer to pay. I am happy to show my FB seller rating as well as rx8club rating to prove legitimacy.

Thanks!
