II Much Fuel Vents??????

[CSG]

I will add that he sent out quite a few "new order" vents before he ever filled my order. He promised me a refund 3 times and I never received one. During our dealings, I called & emailed several times with no immediate response. The responses that I did receive came directly after speaking negatively about him on this forum and on FB. The product that I finally received was a cheaper version with different mounting then what I ordered. Personally, I would not recommend doing business with him.

Just a quick side note, you really shouldn't vent the tank directly into a charcoal canister. I know lots of people are doing it and there are several products out there to facilitate this, but it's bad practice.

If you look at what the factory did when they added charcoal canisters, they added a vapor separator first. This is essentially what a IIMuch can is. I still run the factory separator in my Camaro but without the charcoal can. My garage doesn't smell like fuel at all. ****Side note in a side note - most guys that complain about their garage smelling like fuel still have carburetors and that is typically the source of their issue. ****




That is to keep liquid gasoline out of the charcoal. Once the charcoal is saturated it is junk. Later tanks were all built so that you can't fill them all the way or they have a vapor dome on the top. That allows the fuel in a "full" tank to expand without pushing liquid to the charcoal canister. This is a vapor dome.

That aside, the IIMuch vents are awesome but it doesn't matter because they can't be delivered in a reasonable time frame.

I simplified my vent system down quite a bit with my Tanks EFI tank... bypassed that fuel separator thing behind the seat (which I never really liked anyway)

I have a 90° 5/16 hose barb fitting high up in my filler neck near the non-vented cap. The barb is NPT and screws into the steel filler neck. The neck is thin wall steel, but I tapped it and it works adequately. That barb connects to the steel line going to the front of the car (using 5/16 rubber hose), and the steel line goes to the charcoal canister.

The vent port on top of the fuel pump module goes to both of these two vents which are set up "in parallel" with eachother.






The rollover valve is mounted upside down. When the charcoal canister is activated by the ECM, the tank draws air in through this valve. When the car is off, the valve seals up and doesn't let vapors out. I know that's not the purpose of that rollover valve, but the odds of me rolling the car over are essentially zero.

The mushroom vent valve is there for safety. If the CCP system fails to operate or something, the mushroom valve will bleed off pressure before it becomes dangerous.

I've had this setup for many years now and it seems to work beautifully. Never get pressure build up in the tank (positive or negative), and never get any smell in the garage.

II MUCH Status Update 4 FEB 26
Our site is back up. The hosting issue is resolved.
If you need to contact II MUCH the only method we monitor is the chat function on the www.iimuch.com web page. We have a back log of people to get in touch with but should be resolved soon.
The business did temporarily pause due to the damages caused by tariffs. We've made some major changes to avoid closing our doors for good but we are looking at halting orders to the US at least until shippers are able to handle our USMCA tariff exempt goods without randomly applying massive and inappropriate fees to us or our customers.

appreciate the update. on some level, I feel bad for the guy....I hate to see the tariff games affect small business owner. but at the same time, the order was placed 3 months before the tariff tsar was in office and 6 months before any talk of tariffs. if you cant turn an aluminum box around in 6 months, you should probably stop taking additional orders for aluminum boxes.

It's been 8 months since I placed my order with no word from II Much. I have left voice messages, emails, and chat requests. I will reach out to my cc to recoup my payment. I'm located in the US; Canada might be different.
Order 3699 RIP.

This economy is tough on small businesses. That said, communication goes a long way toward keeping customers happy.

Same issue here. My order # is 3721 placed March 30th, 2026. I have left messages, emails, and used the chat that he is supposedly monitoring. Not a peep from him. His website even states the tariffs will not affect him dated April of 2025. I collect vintage audio receivers (well, I try not to) and have received 2 from Canada in the last year. The tariff charges on those were about 12% of the sale price. And a chunk of that 12% was the charge for UPS to collect the money from me. I understand materials cost will go up but I'd pay the difference to get a good product. Hell, I'd feel better even knowing I wasn't going to get it, if he'd just string me along a little with false promises!

"Tariff Update 2 April 25
Posted on 2 Apr 19:19 , 0 comments
New tariffs were announced by the Trump Administration today. Fortunately they've continued the exemption for products compliant with the USMCA treaty which II MUCH products fall under. This means there will be no immediate tariff related price increases. Though some of the inputs, or materials we purchase, to build the products such as stainless steel are going up. We'll attempt to absorb those costs as long as practical.
NOTE -- if you recently received tracking for your order its delayed due to some of the issues with properly coding harmonized tariff schedules. If it doesn't go live soon check your email for updated tracking.
This has all been highly disruptive to getting orders out, but things are improving here and if you have a backorder it should be headed your way soon"

Update.
Filed with Discover shortly after the last post. He can't respond to me, but when they did a chargeback, he responded to them. He sent them proof of my order, nothing else. No tracking number, no refund information. Because he responded with that, I now have to wait until September 25th to get my money back from Discover. He knows what he is doing. All he had to do was communicate. There are tons of people on other websites with the same problem. At this point I consider him a smalltime Frank or Mark. Maybe I'll actually get it since he doesn't want to lose the money so bad that he's fighting it. Hell, it's less than $300.

Yeah, at this point I’d quit waiting on them. Nearly two years with the same “materials are coming” story and now straight to a generic voicemail is a pretty big red flag. I’d dispute the charge with the card company and keep all the emails, call logs, and order confirmation handy. Shame too, because their vents were a solid product and well regarded.
