Has anyone gotten the extensions for the M2 fuel tanks? Only place I can find is manufacturer in Canada.

Gord is the inventor of them, great guy. I have never seen anything similar online.

I bought them and really like them. Funny, cause we are on a trip and I was telling DW today how much easier they make fueling up. Good investment. And Gordan’s customer support is great.

And I forgot to say I have them and love them!

These are worth every penny. Much cleaner and it actually holds the fuel nozzle.

Have them - love them. I don't understand why they aren't on a Seneca to start with. They do save the paint job by the filler neck.

I'll continue the praise for them. I have them and love them also. Allows you to fill the tanks fuller. I have easily gone 500 miles with fuel to spare once I put these on.

Wished I had them from the start before I beat up mu paint job. Great idea, great service.

I had posted about them awhile back just like this post. I was also wondering about them. I ended up buying them. My only regret was waiting to buy them, should have bought sooner.
Best customer service I’ve had in a long time. I had some questions come up so I emailed Gord in Canada....my phone promptly started ringing. Gord immediately called and all my questions and concerns were answered.
Can’t say enough nice things about Gord.

I understand everyone's love affair with these extensions, but I need to know how much additional fuel can be stuffed in my tanks (without causing overflow issues) before I can think about falling in love with them. I don't have any problems with the stock setup, but would like additional capacity. Any real world, before:after results to report on the volume extension front?

Does anyone have a picture of these or a link?

[Mountain Cajun]

Extendafill.com I’m trying to order some now but I can’t get the site to work. Just emailed them.

I love mine and the customer service from Gord is AMAZING - I have read someone was able to get 7 more gallons of fuel - I think that I get 5 but I don’t completely fill the neck ( it would have to be filled a few ounces at a time because of the foaming ) a very good investment for the convenience and added fuel capacity Les

[Mountain Cajun]

Y’all are right. Customer Service is Great! Got my set ordered!

[RVermont]

I get about 4-6 gallons depending on the truck stop. If filling at gas station with regular pumps I can get close to 6-7 but that is really starting to fill up into the neck. Even though these are 70 gallon tanks I really only feel comfortable with 45-50 gallon fill ups. What that is worth is really up to the individual. For driving it is about an extra 30-40 minutes. For boondocking it is and extra 8-12 hours of generator time.

They speed up the fill process as the fuel hose stays in the tank much more securely and shuts off closer to full then without these.

If you are ready filling to the point of having fuel In the fill tube you might not see as much increase. I used to fill just below the tube now fill to the seam where the extenders connect to the tubes.

I have them too... and am very satisfied!!!. I have not really measured how much more fuel I can add, but it appears to be at least 3/4 of an inch.
I understand your concern on the overflow questions, I had them too.

To satisfy my own doubts... I tried to make them overflow by putting every drop of fuel I could in our tanks, knowing that if they did - we had a place to capture and deal with the additional fuel.

We arrived in Fruita CO and filled up the Seneca until the fuel was half-way up the extensions and capped them off. (we could not take another drop of fuel) We proceeded 5 miles to the concert venue where we stayed five days without running our on-board generator except for the first 3 hours after we arrived and were setting up our camp. (we brought an auxillary gen set for the entire group of RV's we partied with)

We went the entire week without any fuel expansion/escape from our tanks - period. We did come prepared with two oil-drain pans that we put under our tanks, as I actually anticipated that we would have some overflow. Since we were running an auxiliary diesel generator - that was where the overflow fuel was planned to go - but never had to.
