Extensive Testing Scope: JoyFans car fuel leak detector looks small, but it is good enough to deal with the auto sealing detection and diagnosis test on general vehicles and widly workable for multi-systems (including exhaust system, intake system, cooling system, fuel system, and EVAP system), gas lines, cylinder's internal mechanical parts, and engine air tightness. When testing the EVAP system, please check the real-time pressure and turn off the working switch in time.

Visual Detection: Automotive smoke leak detector works by vibrating the specific tester oil (or baby oil) into smoke, and blowing the smoke into the sealed systems to be tested. Oil gas can be quickly generated and transferred into the entire tested system in about 2 minutes. If there is a leak in the sealing system somewhere, gas will come out of that place, just fix it. No need to prepare or rely on other air machines, the instrument has its own built-in air pump to save cost and effort.

WHY YOU NEED IT: This Fuel Line Disconnect Tool makes fuel filter replacement easy. The quick disconnect coupler fittings have a locking mechanism inside the outer housing that goes over the lip of the fuel filter while the tool gets under the locking mechanism and releases the inner lip.

APPLICATIONS: This disconnect tool is necessary for Fuel, Heater, and A/C line service on many late model vehicles. Use it to release locking mechanisms on 3/8-inch and 5/16-inch fuel lines on 1989 and Newer GM, 1990 and Newer Ford, and some 1990 and Newer Mazda Vehicles.

TIPS: Relieve the pressure in the fuel line before disconnecting it, and remember to pull on the line after the spring (locking mechanism) has been released. Some Fords have “Blue Clips� (pictured in this listing) which can be released with a screwdriver, but you'll need this fuel line disconnect tool for the other side of the Ford fuel filter.
