Not as pictured

June 22, 2015
Could have been made better picture should be updated to show the actual cap. The steel roll pin on the cap cuts into the aluminum cap so I don't see it lasting long.
Cons:
  • Cap Should Have A Gasket
  • Roll Pin On Cap Wears Alu
  • Does Not Include Bolts
  • Not As Pictured
No, I would not recommend this product.

Excellent design, average execution

February 10, 2014
The design is great, although you might need sticky fingers in order to get the button to rotate, thereby getting the cap open. My gripe is with the sub-par machining on the threads. Be prepared to knock some of the edge off the threads and add some wax as a lubricant in order for proper use. For $100+, this shouldn't be necessary. It would also be a nice touch to have an o-ring at the seal. The cap is non-vented.
Pros:
  • compact clean look
Cons:
  • needs tlc from manufacturer
Yes, I recommend this product.

You list two tank vents as rollover protection, will these give the proper venting the tank may need?

Part #91012521 is a non-vented cap. The rollover vents 458400 and 458364 will provide sufficent venting for non-exotic fuels in normal conditions.

Part # 91012521 A gas tank needs to be vented or have a vented cap. On this cap there is not a dedicated vent hole so another part of the fuel tank will need to have a vent. As fuel is drawn from the tank if it wasn’t vented would cause the engine to starve on fuel. Air has to replace the fuel as it leaves the tank. Another scenario is temperature. If a tank weren’t vented and was subjected to higher temperature or in severe cases sits in the sunlight the contents will expand and the vent will eliminate the pressure in the tank. Air getting past the threads on the cap in question will not cause problems but will also NOT serve as a vent that is needed on all fuel systems.

Since your tank is vented then you do not need a vented gas cap. This sealed cap will work fine.
