Quctaki Fuel Injection Pressure Regulator Set — Direct-Fit for 1993–1996 Chevy Trucks & SUVs, OE Replacement

Quctaki's Fuel Injection Pressure Regulator Set restores and stabilizes fuel rail pressure for select 1993–1996 Chevrolet trucks and SUVs, replacing OE numbers 19143609 and 17112907.

If your older Chevy is showing signs of inconsistent fuel delivery—hard starting, rough idle, or decreased fuel economy—this direct-fit regulator kit is designed to bring the fuel system back to specification. Built to match the original mounting points and quick-connect fittings, the kit includes the components you need to replace a worn regulator without modifying the fuel rail or manifold.

How does this regulator set affect everyday driving?

Replacing a failing regulator stabilizes the fuel pressure that the injectors rely on, which improves throttle response and reduces irregular idling. You may notice smoother acceleration and fewer stalls if pressure was previously fluctuating.

• Reduces hard starts by restoring correct fuel pressure at key engine states.
• Helps smooth idle quality and reduces surging under load.
• Supports more consistent fuel atomization for steadier acceleration.

Which Chevrolet models and years will this part fit?

This kit covers a wide range of GM light trucks and vans from the early–mid 1990s, fitting fuel rails designed for the same OE style regulator. Confirm compatibility with the listed model years and known part numbers before ordering.

• Covers 1993–1996 Express/G-series vans, 1993–1995 C/K series trucks, and 1993–1995 Suburban/Tahoe/Yukon models.
• Also fits select 1992–1995 Caprice, Lumina APV, S10, G10–G30, P30/P3500, and Safari variants.
• Replaces OE part numbers 19143609 and 17112907 (also PR113T, 143-426).

What does installation look like? Can I do it myself?

Installation is straightforward for anyone comfortable working with simple hand tools and basic fuel-system safety. The kit uses the factory mounting points and quick-connect fittings so no special adapters are required.

• Typical install time: minutes to an hour depending on access and experience.
• No fuel-rail modification or machining required—direct replacement design.
• Follow standard safety steps: relieve fuel pressure, disconnect battery, and take fire-precautions.

What performance improvements should I expect after replacement?

Once the regulator maintains correct pressure, drivability and efficiency usually improve, especially if the old regulator allowed pressure loss or oscillation. Results depend on overall fuel-system health and other engine conditions.

• Smoother idle and reduced engine surging under light loads.
• More consistent starting behavior when cold or after sitting.
• Potential for improved fuel economy if the previous regulator caused rich running.

Who is this for: This Quctaki regulator set is intended for DIY mechanics, independent shops, and fleet owners maintaining 1992–1996 GM vans, trucks and SUVs that use the specified OE regulator style. It’s a practical replacement when you need a cost-effective, direct-fit solution to restore fuel pressure control without altering the fuel rail. Always verify the vehicle’s year, model, and OE part number before purchase to ensure proper fitment.
