Aeromotive 15632 Liquid-Filled Fuel Pressure Gauge 0-15 PSI 1.5 in Carbureted

Vehicle Fitment

• Universal - compatible with any carbureted fuel system equipped with a 1/8-inch NPT gauge port in the fuel pressure regulator, fuel log, or fuel line
• Designed for carbureted fuel pressure monitoring in the 0-15 PSI range - typical carbureted EFI bypass and mechanically regulated fuel systems operate between 3 and 12 PSI
• Suitable for street performance, drag racing, oval track, and road racing carbureted applications

Fitment Notes

• Installs in any 1/8-inch NPT port - including Aeromotive regulator gauge ports, fuel log gauge ports, tee fittings, and inline gauge adapters. The 15632's 1/8-inch NPT male fitting threads directly into standard 1/8-inch NPT gauge ports without adapters on most Aeromotive regulators.
• 0-15 PSI range - carbureted applications only. The 15632 is calibrated for carbureted fuel pressure ranges. For EFI applications operating at 40-100 PSI, use Aeromotive PN 15633 (0-100 PSI).
• Mounting hardware is not included - the gauge is designed to be installed directly into an NPT port on a regulator, fuel log, or tee fitting.
• This product is not legal for sale or use on emission-controlled vehicles except when used as a direct replacement part matching OEM specifications.
• Sold individually - one gauge per package.

Features

• Integral Equalizer Valve - Temperature-Compensated Accuracy: Aeromotive's key innovation in the 15632 is a custom integral equalizer valve that allows the liquid-filled gauge case to be instantly equalized to atmospheric pressure - immediately correcting any temperature-induced pressure reading error without removing the gauge from the fuel system. Standard liquid-filled gauges are temperature-sensitive: as under-hood temperatures change, the glycerin in the gauge case expands or contracts, causing the needle to drift high or low regardless of actual fuel pressure. The equalizer valve eliminates this limitation, providing accurate readings at any operating temperature.
• Liquid-Filled for Durability and Readability: The glycerin-filled gauge case dampens needle oscillation caused by engine vibration and fuel system pressure pulsations - providing a steady, readable needle position during engine operation rather than the erratic needle movement seen in dry-fill gauges installed on high-performance engines. Liquid filling also lubricates the internal mechanism and protects the Bourdon tube from fatigue under continuous pressure cycling.
• 0-15 PSI Full-Sweep Analog Display - White Face: The full-sweep analog display provides easy, at-a-glance fuel pressure readings across the complete 0-15 PSI range, with a white face, black numerals, and black pointer for maximum contrast and legibility under both bright and low-light conditions.
• 1-1/2-Inch Diameter - Compact Installation: The 1.5-inch (38.1mm) gauge diameter is compact enough to install directly on fuel pressure regulators, fuel logs, dash panels, or gauge pods without requiring large cutouts or extensive mounting hardware.
• Heavy-Duty Stainless Steel Case - Chrome Bezel - Shatterproof Lens: The stainless steel case provides corrosion resistance and structural durability in high-heat, high-vibration engine bay environments. The chrome bezel provides a clean, finished appearance, and the shatterproof plastic lens protects the gauge face from impact damage without risk of glass fragmentation in the event of a breakage.
• 1/8-Inch NPT Connection - Standard Gauge Port Size: The 1/8-inch NPT male connection mates directly with the standard gauge ports machined into Aeromotive regulators, fuel logs, and most aftermarket fuel system components - no adapter fittings required in most installations.

Product Description

The Aeromotive 15632 is a 0-15 PSI liquid-filled analog fuel pressure gauge designed for carbureted fuel systems - the companion gauge to the 15633 (0-100 PSI EFI gauge) and the correct pressure range for monitoring carbureted bypass regulators and mechanical fuel pressure regulators operating in the standard 3-12 PSI carbureted range.

Aeromotive's key innovation is the integral equalizer valve that immediately corrects temperature-induced pressure reading errors - a common frustration with standard liquid-filled gauges that drift high or low as under-hood temperatures change throughout an engine run. The 15632 eliminates this by allowing instant case-to-atmosphere equalization. The liquid-filled case provides smooth, stable needle readings despite engine vibration and pressure pulsations. The 1.5-inch white face gauge mounts directly in any 1/8-inch NPT gauge port with its 1/8-inch NPT male connection - no adapters required on most Aeromotive regulators and fuel logs. Stainless steel case, chrome bezel, shatterproof plastic lens. Universal fitment. 1-year warranty.
