Question: What are Retrofit Fuel Modules?
Answer: A retrofit fuel module is a device that allows you to convert your vehicle's fuel pump system to an in-tank EFI solution. Retrofit fuel modules can be used to replace an external fuel pump with an internal one, which can help eliminate issues like vapor lock and cavitation. Additionally, some retrofit fuel modules can operate with an external fuel pump by use of a device called a Bolt In Pick Up Assembly (BIPUA).
Question: Why don't your poly tanks include connections for the factory fuel and vent hoses?
Answer: Our poly tank is designed primarily for aftermarket in-tank fuel components and surface mounted in tank fuel modules. These components all include their own ports or barbs for connecting fuel hoses and vent hoses. If an installation requires additional hose barb fittings we recommend using nitrile or viton gaskets on the fitting you choose.
Question: How do I use a poly tank with an external fuel pump?
Answer: A "BOLT IN PICK UP ASSEMBLY" can be installed on the mounting pad of our poly tank. This unique assembly includes ports for fuel supply, fuel return, and venting. The installation will require plumbing the factory fuel hoses to those individual ports on the assembly head. We recommend using a Tanks Inc brand Bolt In Pickup Assembly (part number PTA-G). To complete this installation the following components will also be required:
a) Quantity of one (1) Tanks Inc 6-Hole Nitrile Rubber Gasket (part number 3G-N)
b) Quantity of one (1) Tanks Inc 6-hole Split Ring (part number 3TR)
c) Quantity of six (6) 10-32 threaded screws 3/4 inch long
Question: What other accessories are required to install an in-tank fuel pump or sender on the poly tank?
Answer: Manufacturers of fuel tank components typically include installation instructions with their products or online links to view directions. If they don't, best practices are always suggested. Most products will require nitrile rubber or viton gaskets and seals to be used instead of cork gaskets with a poly tank for a leak-free seal. Additionally, in-tank fuel pump hangers and senders may also require an internal steel C-shaped mounting ring (pre-threaded) or a flat steel shim to be used for proper compression on the internal poly tank wall. Be sure to check the installation directions of those products prior to purchase or contact us so that we may suggest a solution.
Question: Does your poly fuel tank include a baffle?
Answer: Our poly tanks are designed with a large baffle wall to reduce side-to-side fuel slosh. During development we evaluate the location and size of the baffle wall to allow for internal fuel component installation space and overall impact on external features.
Question: Can the original fuel gauge sending unit be used with your poly tank?
Answer: No, due the original senders unique spin-lock mounting flange and o-ring sealing design, it cannot be installed on our poly tank. An aftermarket surface mount fuel sender will have to be used instead. We offer our own custom designed fuel sender that can be wired into the existing fuel gauge harness under the hatch floor and operate the factory fuel gauge or any impedance (ohms) operated programmable fuel gauge.
Question: What fuel gauge and sender options do I use with a poly tank?
Answer:
Option #1 is to retain the original factory fuel gauge and pair it with our 10.0" long custom fuel sender.
Option #2 is to replace the factory fuel gauge with an electronically programmable fuel gauge that has a working impedance range of 0-300 ohms and pair it with our 10.0" long custom fuel sender.
Option #3 is to replace the factory fuel gauge with an aftermarket gauge and match the impedance range to a 10.0" long tube, reed, or remote-sensing style fuel sender of your choice.
Question: Which in-tank retrofit fuel pump hangers do you recommend?
Answer: Depending on the fuel system requirements of the engine, your budget, and ease of installation you desire, there can be many options to choose from. If you don't know where to start, reach out to us via the CONTACT PAGE and we can assist you. Please include the engine designation, fuel system type, engine modifications, and any changes which you may make in the future to your vehicle so that we can address your options. Popular pump hanger brands include: Holley, Aeromotive, RCI, and Tanks Inc.
Question: Can you manufacture a custom poly tank for any vehicle application?
Answer: Prior to any poly tank development our team conducts extensive research into the viability and sales opportunity for each year/make/model. If you're interested in having a poly tank produced for a very rare or low production vehicle, we are likely unable to meet that request.
