Mercedes Fuel Line Pliers

Wouldn’t it be great if someone invented a single tool that can disconnect all the various types of connectors on fuel, vacuum, and transmission cooling lines on all the vehicles we see every day? This is not a rhetorical question: we own a drawer full of various tools that can each disconnect one type of connector, but not others, which can be annoying at times.

While we own enough tools to disconnect most fuel and vacuum line connectors on most vehicles, we have never been able to understand why it is sometimes necessary to buy yet another special tool to do something as simple as disconnect a fuel or vacuum line on a new model. Sadly, though, some questions in life have no answers but fortunately for us, some tool companies spend a lot of time pondering the question of how to make tools that not only do more things than similar tools but how to make tools that do more things better than similar tools.

One case in our point involves fuel and vacuum line disconnect tools, or more precisely, special pliers that are intended to disconnect as many different types of connectors as possible. We have all seen them, and we daresay that most of us have all wasted money on some examples that simply do not work as well as their manufactures claim but there are notable exceptions to this, one such exception being this particular pair of-

This tool is made by Cal-Van Tools, and it is is not just another fuel line disconnection tool. While this particular version of a disconnect tool is designed primarily for use on both quick connect, and slide and lock-type connectors on the fuel and vacuum lines on various Mercedes models, it also works on the same types of fuel and vacuum line connectors on other vehicle makes and models. Examples include, but are not limited to most Toyota, almost all VAG-group vehicles, and most Asian vehicle brands and models.

Note the small cross-section of each arm of the pliers, as well as the large gap between them just where the body of a connector would fit if you have to approach a connector long the axis of the line you need to disconnect. The small cross-section makes it an easy matter to engage the jaws with the locking tangs of a connector in situations where several lines are routed closely together, while the large separation between the jaws makes it possible to disconnect even the bulkiest connectors easily.  As a purely practical matter then, this tool can replace the vast majority of the disconnect tools most of us own, which can never be a bad thing. 

So what do you think of this particular fuel line disconnect pliers? Is it something you could, or would use, or do have another way of disconnecting stubborn or difficult to reach fuel and vacuum line connectors? Tell us about it in the comments section below. If however, you feel that you might want to reduce the number of line disconnect tools you already own, you can order this tool directly from the manufacturer’s website.
