VSR/E External Remote mount Fuel or Differential Vent System
NEW PRODUCT: Shipping Spring of 23.
NOTE: If you are waiting on a VSR and want this external mount option we will switch at no charge.
The II MUCH VSR (Vent System, External) relocates fuel tank venting from the cap on pre-emission era vehicles which were not equipped with evaporative emissions systems. This provides the following benefits;
- Dramatically reduce or eliminate fuel vapor odors
- Eliminates fuel spillage and overflows on the track or at the show
- Easily meets airflow demands of very high volume fuel pumps, preventing pump failure due to cavitation.
- Allows air to exit tank while fueling preventing "burps"
- Relocates venting from leak prone vented fuel tank caps.
- 40 micron air filtration
When used for differential housing venting it provides the following benefits;
- Eliminates gear oil spillage
- Reduces gear oil odor
- Prevents pressure buildup inside housing which can push lubricant past axle seals, especially important in floating axle arrangements.
- Integrated 40 micron 304 SS Filter
- Mounting Bracket, 6061 Aluminum
- Mounting hardware, 18-8 Stainless Steel
- Temperature indicating decal

The II MUCH VSR vent system features two 1/4 NPT ports on the bottom.
If the VSR is mounted inside the vehicle the "Tank" and "Filter" ports on the bottom of the unit will need adapters. And a bulkhead fitting (below) will be needed to thread the included filter to the underside of the vehicle. A second bulkhead fitting may be required if the fuel tank is outside of the vehicle. See installation instructions for more details.
If the VSR is mounted externally the included filter can be threaded directly into the port labeled "Filter"

Can II MUCH vents be used to replace an evaporative emissions canister?
No, this would violate the Clean Air Act, and is against the law.
Do II MUCH vents contain activated carbon or any items requiring maintenance?
No, there is no charcoal in the unit or items requiring maintenance.
Is it compatible with E-85?
Yes, Its compatible with properly stored E-85, but not aged and contaminated fuel.
Will this eliminate the fuel odors in my car or garage?
Most customers say the odor has been eliminated or dramatically reduced. The installation instruction go into detail about this.
What is that port on the bottom of the canister?
Look at the “Fittings” tab on the product page for examples available to purchase from II MUCH.
Can I use one unit for both fuel and differential?
No, this would cause gear oil and fuel to mix.
How high does the unit need to be mounted?
Enough that fuel in the vent line will eventually drain back into the tank via gravity.
Does the filter on the bottom of the unit need to be replaced?
No, but it should be inspected and cleaned with carb. cleaner periodically.
Is there a roll-over valve in the unit?
No, but we recommend gravity style as they don’t restrict airflow the way one or two way check valves do.
What is included with the unit?
The first page of the installation instructions lists everything the unit ships with
Can I mount the unit sideways or under my tank?
No, please read the installation instructions for more details.
Why can’t I buy this outside of Canada or the USA?
We’re working on this, but its not an option yet.
Why can’t I buy II MUCH products from Summit Racing anymore?
Summit is great, but we are focused on selling direct during COVID-19 due supply chain disruptions.
