CARB compliant fuel cans (plastic)

admin

This has been discussed before but I can't finds the old thread, what fuel cans (plastic) are you finding that don't leak, or what modifications are you doing to make them like pre-CARB cans? I found the $25 Harbor Freight Midwest can to be reasonable, I am able to use it so far with no leaking although it is painfully slow putting 5 gallons into a vehicle. It is also less than 6 months old and have only used it twice. On the other hand my more expensive Blitz always leaks and this weekend on the road the vent plunger fell of and went to the bottom making it useless, fortunately I was able to screw on the cheap HF spout and empty it that way. I saw some kits where you install a new fill tube and a vent, my concern is the vent leaking while offroad on rough trails etc. (I am using diesel so no worries about the rapid expansion of gasoline here).Miller Challenger 172Miller Thunderbolt AC/DC 225/150Miller Maxstar 150 STLVictor 100CVictor JourneymanOxweld OAHarris O/ASmith O/A little torchNo, that's not my car.
Reply:I have had good luck with E-Z pour brand spout replacement kits. The trick is to NOT drill the hole for the vent cap too large. You want that vent cap to be difficult to install, so it retains a snug fit. I have had to use a rubber mallet on them to get them to seat properly. But if you do that right, these have never leaked on me. Look for the kit with two caps (usually one black and one yellow). One of the two caps will likely fit your can and the other will not. I am not sure if they have different thread sizes or what, but its been the case for me where one always works and the other leaks. https://www.tractorsupply.com/tsc/product/ez-pourI think the instructions call for a 1/2 inch drill bit but I used a 31/64 inch bit for a tighter seal. At one time the instructions for these actually recommended a 31/64 inch size bit, but at some point they changed the instructions.Miller Multimatic 255
Reply:Also, make sure you place the vent cap above the max fill line of the can you choose, and better to seat it on a flat surface rather than say the round part of a handle. Its also good to avoid the mold seam as your site for inserting the vent.Miller Multimatic 255
Reply:I don’t know who thought having that stupid spout and no vent was a good (safety?) idea.My fix is to install a small tire valve stem up top behind the handle with the valve removed. Then use the cap to seal it. The other modification is to remove the spring in the spout.To use it you lock the spout open, remove the cap and it pours pretty normal without having to push the spout to keep it open. There are a bunch of Utube videos of this. Simple, cheap and it works.Ernie F.

Reply:No-Spill cans are very well made and work well.  Only downside is having to hold your thumb on the button, which gets old, but I drilled a hole through the plastic shroud behind the button, so I push the button now, then slide a drill bit or rod through the hole to hold the button open.  Obviously only do this if you KNOW you can empty the full can without overflowing your tank.-DaveXMT304 with: 22A Feeder, or HF251 Hi Freq DC TIG air cooled
Reply:I just bought one of those plastic midwest cans for about ten bucks less at TSC a while ago. I found it worked fine if I waited for it to glug but leaked from between the telescoping spout when I added a vent. So, I pulled the spout in half did a little trimming to make everything round and slipped a piece of vinyl hose between both sides. Pretty happy with it now.

Those ez pour spouts worked great for about a year or two, but If I wasn't careful when tightening the lid the flimsy flange at the base of the spouts would get misshapen, And/or the thin rubber gaskets would tear. Then they would leak from under the cap when pouring. Menards has a knockoff version for five bucks that suffers from the same problems. I also had the same trouble with those vents, wrapped a little bit of teflon tape around the part that pops into the can to make them fit tighter in the half inch holes. Seems to work.
Reply:I've used the replacement spouts from TSC for years, they work great, I'v also gutted some of the "safety" spouts,  added some hose and used a crutch tip or something similar for a cap, I think I have 2 like that that have been in service for 5 years or more. Whoever came up with the "safety can" & spout ideas has really got it together, the damn things are 100% safe because they're 100% unusable!NRA LIFE MEMBERUNITWELD 175 AMP 3 IN1 DCMIDSTATES 300 AMP AC MACHINELET'S GO BRANDON!"Those who would give up essential Liberty, to purchase a little temporary Safety, deserve neither Liberty nor Safety.” BENJAMIN FRANKLIN
