Almost a year with my F150 and I’m loving the capless design. Don’t see how anything more than fine dust could get onto the flap but I haven’t even seen that happen and I drove on quite a few dry gravel roads in rural Maine this summer…
Yep, how often have we advised someone with a CEL and EVAP code to re-tighten the gas cap, and/or replace it?
Not just the gaskets!
Back in my gas jockey days, it wasn’t unusual to have a car come in sans gas cap. Because some of our guys were occasionally guilty of leaving a gas cap on top of the pump after filling a customer’s tank, we had a shoe box full of random caps, and if a customer came in w/o a gas cap, we would let him rummage through that box to find a replacement.
A solution in search of a real problem.
More failure modes than the alleged original problem.
California thinking (and I’m from there).
I can’t tell you how many failed fuel pumps I’ve had to replace or how many contaminated fuel systems I’ve had to fix because the car had a capless fuel filler.
I can’t tell you because I’ve never seen it.
What has not been discussed yet is the cost of repairs. What happens when the rear quarter panel takes a hit. What is the cost of that new filler tube with the complex capping system?
For comparison, I recently replaced the entire filler tube on a 1995 Mazda B2300 and the part alone was $140, and it included the cap.
I imagine the body parts and paint needed for the repair would constitute the majority of the cost. A hundred bucks either way isn’t going to make any difference.
I don’t know if I’m more impressed that you could still find parts for a 31 year old car or that you found it that cheap.
2020 transit Connect 2.0L here and we’ve had (2) connect since 2014 and never had an issue with the capless systel. However this doesn’t mean you won’t have issues. I’m concerned with water getting into the system when it rains. Plus I’ve been searching for a way to lock this or install a plug within the filler tube.. nothing’s available. just keep the rubber seal pliable and clean from dirt.
Living in Florida we have very heavy rainstorms and hurricanes, plus I have an unlimited car wash membership. Truck 13 Y.O., car 6 Y.O., no water intrusion yet, knock on wood.
Tester provided a source for a cap that fits over capless systems.
You have to be kidding.
This is getting ridiculous! We engineered an expensive and unreliable fix for a problem easily solved by replacing a 10 dollar fuel cap IF it got damaged.
Lets just end the madness with unreliable lifter eating displacement on demand engines and these absolutely ridiculous capless fillers.
My Tahoe has a capless filler and it really upsets me all the filth on the little flap. If anyone doubts me look at the micro particles you wipe off if you so inclined.
Ok, so you will tell me, Rick, just change your fuel filter more often! Oh…Wait that’s right we did away with those too.
It seems vehicles reached their pinnacle in 2005 or so. Its been downhill from there.
I have a 2013 Ford with 168,000 miles, 2018 Cadillac with 90,000 miles, both with capless fuel filler. I will let you know if either of the cars ever has a fuel related issue. 
You’re looking for a solution to a problem that doesn’t exist.
Again, sell it. Lots of older vehicles with gas caps available.
Honestly Mike, I believe you are correct. I have not had a problem. Its just that I am having a hard time enjoying this vehicle knowing that the lifters may fail at anytime along with the transmission.
I am also very suspect on the capless filler, I just don’t trust it to last 300k miles.
I don’t really want to be Captain Obvious, but I will ask the following questions, anyway:
Why did you buy it in the first place?
Why don’t you sell/trade it in the near future?
My 2005 4-5unner was the first vehicle I ever owned which didn’t have an external fuel filter. I was extremely skeptical of this type of system because the dirt is NEVER removed from the system unless you drop the tank.
So, after over 300k miles in 2014 I bought a new Highlander and never ever had a problem with any part of the fuel delivery system or injectors.
I’m no longer skeptical of this type of system
As opposed to the 70’s-80’s era Chevrolets that never had camshaft or transmission failures?
In hindsight it seems obvious that filtering the fuel before it goes through the pump instead of after is the right thing to do, but we all were skeptical of this setup when it was something new.
