Availability set by the retailer

The RULLINE 3/8" and 1/2" Drive Diesel Injector Fuel Line Socket Wrench Set is a 13-piece socket kit covering metric sizes from 10mm to 22mm for servicing diesel fuel injector lines and related fasteners. The set includes 3/8-inch drive line sockets (10mm, 11mm, 12mm, 13mm, 14mm) and 1/2-inch drive line sockets (17mm, 19mm, 21mm, 22mm), each slotted so the socket can slip over an installed fuel line to engage the injector line nut in tight, confined spaces where a standard socket cannot reach. The sockets are constructed from chrome-vanadium (CR-V) steel with a polished finish for corrosion resistance and long-lasting performance, and are designed to grip fasteners securely to help prevent slipping or rounding. The set is suitable for use on injector lines, fuel points, fuel injector connections, bent pipes, exhaust gas temperature (EGT) sensors, and thermo switches. Each socket is compatible with the matching 3/8-inch or 1/2-inch drive ratchet, extension, or breaker bar. Brand: RULLINE; material: chrome-vanadium steel; quantity: 13 pieces; ASIN: B0CNTCGGT3.

Choosing Sockets & Sets

6-point or 12-point sockets — which should I use?

6-point sockets grip the flats of a hex fastener for maximum torque and resist rounding, ideal for stubborn or high-torque fasteners. 12-point sockets offer more engagement positions for tight clearance, but apply force closer to the corners and are more likely to round a worn fastener.

Do I need impact-rated sockets?

Use impact sockets (typically chrome molybdenum, black finish) with impact drivers and wrenches; standard chrome sockets can shatter under impact loads. For hand ratchets, chrome sockets are fine and are thinner-walled for tight spaces. Match the socket drive size to your ratchet.
