The GS300 and Aristo use a different hanger, listed separately.\"}},{\"@type\":\"Question\",\"name\":\"How much power will the fuel system support?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"The 8AN feed with 6AN return combination has been tested upwards of 1200hp. That is the tested plumbing capacity of the system as configured.\"}},{\"@type\":\"Question\",\"name\":\"What is different about the V2 compared to the V1?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Four things. Stainless stud connectors replace the bulkhead connector, removing the amperage ceiling that restricted V1 usage to Walbro 450 and 485 pumps. Every hanger is hardcoat anodized in house. The stud isolators are Delrin rather than 3D printed or general plastic, so they tolerate heat and alcohol-based fuels. And the siphon venturi is machined directly into the pump bracket instead of being a modified factory piece, which is more compact and flows considerably more. The V2 is the same price as the V1.\"}},{\"@type\":\"Question\",\"name\":\"What pumps can I run on the V2?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"The stud connectors give a practically unlimited amperage threshold, so pump choice is no longer limited by the connector. Fuel pump adapters are available for most popular pumps on the market including brushless options, and each adapter ships with its own instructions via QR code.\"}},{\"@type\":\"Question\",\"name\":\"Should both pumps run all the time?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"No. The pumps should be staged. The car should start, idle and cruise on a single pump, with the second coming on only when demand requires it.\"}},{\"@type\":\"Question\",\"name\":\"Do the dust seals go inside the fuel tank?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"No. The dust seals are for the outer connector only. They are not fuel safe or watertight, so they serve no purpose inside the tank.\"}},{\"@type\":\"Question\",\"name\":\"Is the relay harness specific to my car?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"No. The same relay harness is used across every ASE pump hanger. Standard four-pin relay wiring is identical on any application.\"}},{\"@type\":\"Question\",\"name\":\"Can I run just one pump?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Yes. The hanger runs one or two pumps. For a single pump setup, plug one of the two ports with the supplied 6 ORB plug.\"}},{\"@type\":\"Question\",\"name\":\"Why will the second pump not thread into the manifold?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Because the pump outlet is eccentric rather than concentric — it is not in the center of the pump, so threading it straight up makes it rotate around its center point instead of seating. Snug one fitting into the manifold, leave the second loose enough to still have threads engaged but rotate freely, then walk the pump into position and tighten the fitting up into the cavity using the hex while keeping the pump perpendicular to the base.\"}},{\"@type\":\"Question\",\"name\":\"What size are the assembly screws?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"3mm. Start with a clean Allen key so the heads do not round out, since they are not available locally. Walk around the perimeter pulling the assembly together gradually. A trimmed short Allen key makes the screw tucked under the fuel manifold far easier to reach.\"}},{\"@type\":\"Question\",\"name\":\"Is it E85 compatible?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Yes, anodized for E85 compliance, with Delrin isolators that are safe with gasoline, ethanol and other alcohol-based fuels.\"}}]}\u003c\/script\u003e\u003cscript type=\"application\/ld+json\"\u003e{\"@context\":\"https:\/\/schema.org\",\"@type\":\"VideoObject\",\"name\":\"Why It's Ultimate IS300 Dual Fuel Pump
