Fuel Tank Sending Unit For 1978-1984 Chevy C10 C20 K10 K20 Suburban Blazer & GMC Trucks – 31/40 Gal Tank With Fuel Return & 4 Outlets

About This Product

Got an older Chevy or GMC truck that's acting up with the fuel gauge or struggling to get gas to the engine? This sending unit might be exactly what you need. It's a direct replacement for a bunch of models from 1978 to 1984 – we're talking Chevy C10, C20, K10, K20, Suburbans, Blazers, and their GMC counterparts like the C1500, K1500, and Jimmy. Fits both the 31-gallon and 40-gallon tanks. It comes with the fuel return line (important for keeping the fuel cool and preventing vapor lock) and has four outlets, so it should hook right up to your existing lines. Build quality feels solid – decent materials that should hold up. If your original unit is rusty, leaking, or just giving wonky readings, swapping this in can save you a lot of headaches. Installation is a tank-drop job, so set aside a few hours and make sure the tank is empty. Always double-check the compatibility list with your specific year, model, engine size, and tank size before you order. For a lot of these classic trucks, finding a good new sending unit can be tricky, so having a reliable aftermarket option like this is a big help. Get your fuel system working right and your gauge reading accurately again. Keep that old beast on the road!
