This compact controller supplies three seconds of power at key‑on to fill carburetor bowls, then allows the pump to run only when it detects a tachometer signal (or coil negative on cars without a tach). Built in the USA, it’s potted for weather resistance and includes a self‑resetting fuse and 15 feet of wiring for straightforward installation.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this controller protect my vehicle after converting to an electric pump?\u003c\/h3\u003e\n\u003cp\u003eThe controller constantly monitors engine run status via the tach signal; if the tach stops, the unit immediately cuts power to the fuel pump. This prevents fuel from being pumped into an idle engine or an accident scene, improving safety compared with simply wiring the pump to ignition power.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eShuts pump off when tach signal ceases, stopping fuel flow if engine stalls.\u003c\/li\u003e\n  \u003cli\u003eWorks with inductive (stock) or square‑wave (aftermarket) tach signals.\u003c\/li\u003e\n  \u003cli\u003eFor vehicles without a tach, connects to the coil negative to sense engine rotation.\u003c\/li\u003e\n  \u003cli\u003eFully potted housing resists moisture and vibration in engine bays.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat happens during key‑on and how does it prime the carburetor?\u003c\/h3\u003e\n\u003cp\u003eOn the first turn of the key the controller supplies three seconds of pump power before requiring a tach signal, giving enough time to fill carburetor bowls and prime the system. This brief timed run avoids the need to crank the engine repeatedly to get fuel into the carburetor during cold starts or after maintenance.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eThree‑second timed output at initial key power to top off carburetor bowls.\u003c\/li\u003e\n  \u003cli\u003ePrevents unnecessary long runs — pump only continues with confirmed engine rotation.\u003c\/li\u003e\n  \u003cli\u003eReduces starter wear and eases cold‑start procedures for classic cars.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat installation and compatibility details should I know?\u003c\/h3\u003e\n\u003cp\u003eThe controller is designed for 12V systems and ships with 15 feet of 16‑gauge wire and mounting hardware for most classic car installs. It includes an internal 7A self‑resetting fuse; higher‑current pumps can be controlled by using the unit’s output to drive an external relay.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eIncludes 15 ft of 16 AWG wire and mounting hardware for flexible placement.\u003c\/li\u003e\n  \u003cli\u003eInternal 7A self‑resetting fuse protects the circuit; use an external relay for pumps above fuse rating.\u003c\/li\u003e\n  \u003cli\u003eCompact dimensions (2 × 1.5 × 1 inches) fit tight engine compartments.\u003c\/li\u003e\n  \u003cli\u003eMade in USA and fully potted for durability in automotive environments.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill the controller work with my tach or aftermarket ignition?\u003c\/h3\u003e\n\u003cp\u003eYes — it accepts both traditional inductive tach signals and modern square‑wave outputs from aftermarket ignition systems. If your vehicle lacks a tachometer, simply attach the tach input to the coil negative to allow engine speed sensing and safe pump operation.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eCompatible with stock inductive and aftermarket square‑wave tach outputs.\u003c\/li\u003e\n  \u003cli\u003eCoil negative connection option for vehicles without a tachometer.\u003c\/li\u003e\n  \u003cli\u003eReliable sensing avoids false runs from electrical noise or intermittent signals.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for: Enthusiasts restoring or modifying classic cars and trucks who want the benefits of an electric fuel pump without sacrificing safety. It’s a compact, easy‑to‑install solution for hot‑rod builders, weekend restorers, and anyone replacing a mechanical pump with an electric unit who needs automatic priming and engine‑sensing shutoff.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Does the controller work on 12V systems?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes.
