G GASKET CO. fuel pressure gauge 1.500 in — 0–15 PSI mechanical, 270° sweep","description":"\u003cstrong\u003eMr. Gasket 1561 is a compact 1.500-inch mechanical fuel pressure gauge that shows 0–15 PSI in 1\/2‑pound increments for quick, reliable monitoring.\u003c\/strong\u003e\n\n\u003cp\u003eIf you tune or maintain fuel systems, an accurate, compact gauge gives fast feedback without taking much dash or panel space. The Mr. Gasket 1561 was built to fit most installations: a 1.5\" diameter housing, chrome bezel, and a white dial with clear black numerals make readings simple, while the 1\/8\" NPT male fitting mates with any standard 1\/8\" NPT female port. The gauge uses a 270° sweep for fine resolution and is mechanical—no power required—so it works anywhere pressure needs checking.\u003c\/p\u003e\n\n\u003ch3\u003eHow precise is this gauge for adjusting fuel pressure?\u003c\/h3\u003e\n\u003cp\u003eThe 1561 displays pressure from 0 to 15 PSI with half‑pound tick marks across a wide 270° sweep, which improves needle separation and readability. That resolution is helpful when dialing in a regulator or diagnosing fuel delivery changes under different conditions.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eScale: 0–15 PSI in 0.5 PSI increments\u003c\/li\u003e\n  \u003cli\u003eDial: high-contrast white face with black markings for fast reads\u003c\/li\u003e\n  \u003cli\u003eSweep: 270 degrees for fine needle movement and accuracy\u003c\/li\u003e\n  \u003cli\u003eMechanical movement: no batteries or electrical hookup required\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat size and fittings does it need for installation?\u003c\/h3\u003e\n\u003cp\u003eThis gauge measures 1.500 inches in diameter, designed to mount where space is limited. It connects to any standard 1\/8\" NPT female port, making it compatible with most aftermarket regulators, fuel rails, and factory ports that accept NPT sensors.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eBezel size: 1.500-inch diameter housing for compact mounting\u003c\/li\u003e\n  \u003cli\u003eThread type: 1\/8\" NPT male fitting to match 1\/8\" NPT female ports\u003c\/li\u003e\n  \u003cli\u003eMount options: fits tight dash openings, panels, or fuel-system adapters\u003c\/li\u003e\n  \u003cli\u003eFinish: chrome bezel for corrosion resistance and visual clarity\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow easy is it to read and use while working on a vehicle?\u003c\/h3\u003e\n\u003cp\u003eThe gauge face emphasizes readability with bold black numerals on a white background and a chrome bezel to reduce glare.

Because it uses a standard 1\/8\" NPT connection and a 0–15 PSI scale, it pairs well with many aftermarket regulators and stock systems that operate in that pressure range.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eCompatibility: fits systems using 1\/8\" NPT female ports\u003c\/li\u003e\n  \u003cli\u003eRange: 0–15 PSI covers most carbureted and low-pressure EFI applications\u003c\/li\u003e\n  \u003cli\u003eDurability: metal bezel and sealed face for workshop environments\u003c\/li\u003e\n  \u003cli\u003eUniversality: mechanical gauge works where electrical gauges cannot\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho this is for: The Mr. Gasket 1561 is aimed at home mechanics, tuners, and professional technicians who need a reliable, compact fuel pressure indicator during setup, diagnostics, or regular maintenance. It’s especially useful when dash space is limited or when a simple, power-free pressure readout is preferred over larger or electronic options.\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: What thread size does the Mr. Gasket 1561 use?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: It uses a 1\/8-inch NPT male fitting to thread into any 1\/8-inch NPT female port.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Is the 1561 suitable for electronic fuel systems?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes, it suits low-pressure systems like carbureted and some EFI setups that operate within 0–15 PSI.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"MR.
