491 Fuel Tank Filter Bowl Wrench Nylon 85 mm for 495-4 496 Series

Filter AccessoriesCE / ISO 9001

This is the wrench for the 495-4 see-through bowl. That bowl has eight bumps around its rim, and no standard strap or chain wrench grips them without cracking the polymer. The 491 wrench has eight matching notches cut into an 85 mm inner diameter ring, so the load spreads across all eight bumps at once. It is moulded from reinforced nylon, and the handle ends in a hanging hole sized for a peg or a hook on the storage tank.

❓ FAQ

The 495-4 rim carries eight moulded bumps and nothing else to grip. A strap pulls on the outside of those bumps and crushes them; a chain rides off between them. This wrench has eight notches that sit over the bumps and turns them as a unit.

It is moulded from reinforced nylon, the same family of material as the bowl, so the load goes through the eight ribs rather than through a hard metal edge. That is the difference between this and a steel strap wrench, which is what usually cracks a bowl.

Yes. 495, 495-3/4, 496, 496-3/4 and B10-AL use the same eight-bump rim, so the 85 mm ring indexes on all of them. You do not need a second size when you move between the 495 bowl and a 496 assembly.

Check what came in the box. The 496 assembly ships with a plastic wrench, and if you still have it, that is the same tool. Buy this one when the original has been lost, left on the tank, or when you keep a bowl on a second tank.

Yes, the handle ends in a hanging hole. A peg or a zip tie through that hole keeps the wrench with the tank, which is where you need it when the bowl has to come off at a fill stop.

Description

Product Overview

The 495-4 bowl is held by eight bumps moulded around its rim. A metal strap wrench crushes those bumps; a chain wrench slips off them. This 491 wrench is a ring with eight matching notches at an 85 mm inner diameter, moulded from reinforced nylon, with a hanging hole at the end of the handle. It fits 495, 495-3/4, 496, 496-3/4 and B10-AL fuel tank filters and is meant to be the only tool you need to get the bowl off without breaking it.

Key Features

Eight notches, not a friction grip — the ring indexes onto all eight bumps of the 495-4 bowl at once, so the torque goes through the moulded ribs instead of squeezing the rim.
Reinforced nylon — the same class of material as the bowl, which is why it cannot crack the bowl the way a steel strap or a chain does.
85 mm inner diameter — sized to the 495-4 rim, deep enough that the ring does not cam off when you lean on the handle.
Covers the whole family — 495, 495-3/4, 496, 496-3/4 and B10-AL bowls share the same eight-bump rim, so one wrench covers them all.
Hanging hole — the handle ends in a hole, so the wrench lives on a peg next to the tank instead of in a drawer.

Applications

Draining a 495-4 bowl — spin the bowl off with the ring indexed on the eight bumps, empty it, then refit by hand until the gasket seats
496 and 496-3/4 assemblies — same eight-bump bowl, so the same wrench opens them for an element change
B10-AL bowls — the aluminium bowl uses the same rim pattern and the same wrench
In the truck box — nylon will not rust and the hanging hole takes a zip tie, so it can live with the tank
