Detailed Description

Standard Ignition DS-1807 is engineered for vehicles that use a fuel tank selector switch to route fuel delivery between tanks. The design focuses on dependable electrical operation and a fit that matches the original connector and terminal configuration. This makes it a practical replacement when servicing older GM trucks and SUVs such as the Chevrolet Blazer, GMC Jimmy, and heavy-duty C/K and R/V series models.

This part cross-references OE-style applications such as 15599081 and FS502 for the same use case. If you are searching for a fuel tank selector switch for a 1987-1988 Chevrolet Blazer, 1987 GMC Jimmy, or 1990-1991 Chevrolet R1500 Suburban, DS-1807 is the cataloged replacement to verify against your original unit.

What It Helps Fix

• Inability to switch between front and rear fuel tanks
• Intermittent fuel delivery caused by a worn selector switch
• Electrical connection issues at the switch interface
• Dashboard switch failure on dual-tank GM applications
• Fuel system routing problems on older Chevrolet and GMC trucks

Installation Notes and Tips

Confirm the connector style, terminal count, and original part number before installation. This switch uses a 4-pin male connector with 4 blade terminals, so matching the OE layout is important for proper operation. Verify vehicle fitment against the exact year, make, and model listed for your Chevrolet or GMC application before replacing the original selector switch.

Quality Assurance

Standard Ignition states that its fuel valves and related components are developed with focused research and long-term industry experience to address technician needs and common OE failure points. DS-1807 is built as a replacement part for supported GM applications where the original fuel tank selector switch has failed.
