Breaking News – Walbro Knock Off
Recenly, there is some amount of Walbro fuel pump knock off surfaces on the market. Please be sure yours is not one of them. Here are some ways to identify those knock off products.
- Notice the size difference between the Walbro. Authentic Walbro is slightly shorter while the knock-off ones has a longer body.
-
Notice the difference between the bottom inlets of the two pumps. The Walbro does not have the “vent hole” in the bottom in comparison to the “knock-off” which does. The so called purpose of this vent is to purge the pump due to the way the “knock-off” operates.
- Notice the difference between the two fuel inlets on these pumps, along with the “+ & -“ terminals.
-
In addition to the above stated observations, you will notice that the “knock-offs” have a distinct rattle to them as the Walbro pumps do not. This rattle heard in the “knock-offs” are the rollers moving around in their casing, you are able to shake any of the Walbro Gerotor style pump and there is no rattle to them.
Another way to ensure that you are receiving an authentic Walbro is, of course, getting it from a reputable dealer and which we are here for.
