Yesterday I binged on 30 some of your van build vid's, never have I seen better on You tube. Outstanding build.

[@FreedomStrider]

Thank you ☺️ ...30 videos, you watched like 6 hours of us, you have some endurance, good on you 🤣👍

[@frankiez7414]

flip flops, t shirt, gravel road and filming too. Well done you pair and also for not getting frustrated and pissed off whilst struggling there. good team work there. The lengths that we go to for these vans.

[@FreedomStrider]

Aye we do do a lot for these vans ☺️

[@sprinterdiscovery]

Here I am, panicking as you guys have the fuel tank out of the Sprinter and unable to open it up. There's no going to the local hardware store if the clamp breaks to get a new one! Very well done. Impressed with how you guys research everything, show the innovative ways to get around failures, and get the job done! Thanks for sharing - have an awesome weekend!👍

[@FreedomStrider]

Cheers for the support! That fuel tank twist cap was the hardest thing to do in the whole job, no matter what it would not open! But we managed to not break all the tabs off 😂

[@paufarreny989]

Congrats for the tecnique on the blue rope to open the lid ! Looking great

[@FreedomStrider]

Cheers, took us a fair bit of trial and error 🤣👍

[@UrbanVanlife]

job well-done guys , the it won't start look PRICELESS, the cucumber sandwiches NOW I CAN'T UNSEE THAT

[@FreedomStrider]

Haha I know I'm so glad I caught it on camera!! 🤣 We technically didn't have cucumber sandwiches we had cucumber and sandwiches...though it doesn't sound as cool 😎🤣

[@UrbanVanlife]

@@FreedomStrider well I’ll let that go but I may bring you a cucumber to the meet

[@Andysouthcoast]

Ive just done this on my van and your video has made it so much easier to do. I would not have even thought about doing it with out your step by step guide and helpful tips. Thank you

[@FreedomStrider]

You're welcome! It could have been worse, but always helpful to see someone else do it first before you give it a go. 👍

[@mclucky7086]

Heroics to the very end. Congratulations. Great job and very well presented. Thankyou.

[@FreedomStrider]

Thanks, fingers crossed nothing leaks now 😎👍

[@bash0774]

The relief when it starts 😅 great video well done on the removal and refitting

[@FreedomStrider]

Very big relief, for a moment I thought we might have to drop the tank again 🤣🙄

[@GH-dn3oh]

Thanks for all the effort putting up such a great video. I was watching this to prep for the same work on a friends 2022 3500 XD. After watching it, I went to look at her setup to discover something amazing ... As I looked around, I spotted a unit under her van where I saw "Webasto" on it, and I said "whaaaat?" After tracing things around and looking in the manual, I discovered her van came STOCK with Webasto water heater that is used as an engine pre-heater!!! As you can imagine, this made my work much easier. I didn't have to drop the tank, instead I tapped into the fuel line going to the engine preheater. What's more, it looks like Mercedes makes their own fuel pump bracket that is far superior, and quieter, than the fuel pump bracket that comes with the Webasto Airtop. So I'll be doing some research to figure out how to order one of their brackets, if it's not too expensive, for my fuel pump and hers. For anyone curious about the functionality of the stock engine pre-heater: There's a switch on the center panel to enable it. It will only enable with outside air temp under 40 deg F and can run for only a max of 50 minutes. It does enable the vent blower so it can also preheat the cabin once the engine coolant is hot. It can also be programmed to come on at a later time (like in the morning before you plan to drive away). Like I said, the pump is more quiet but the heater unit is quite loud. Nonetheless, it's a great thing to have and look for it if you have a new Sprinter (I'm assuming it's only on newer ones?).

[@FreedomStrider]

Amazing, I wish our van came with a preheater, especially since ourheater is one of these hydronic heaters, would have saved us the trouble of installing one in the first place! Yes you do have to be careful with some of the preheaters as you said, they have a max time function on, and when we were buying our actual heater we had to dodge the models that did this. It actually seems only sprinters, yes, and srinters especially in Canada, USA and Scandinavia that have these as standard. ;)

[@georgeboydratcliff1036]

You can buy (very cheap!) jam jar openers. They’re a handle with a rubber strap, and work perfectly

[@FreedomStrider]

Yes that would probably work to, just not a tool we had in our arsenal at the time 🤣👍

[@theoteam4641]

Well done both of you, that job is long and hard. I know because I did ours with a hell of a friend. And I ended up cutting the fuel line into the tank short lol, so I’ll have to take it down and do it again lol

[@FreedomStrider]

I remember you saying, but hopefully you figure out why it only works when 3/4 full 🤣

[@drewbradford7608]

Thank you Thank you Thank you!!!!

[@FreedomStrider]

You're welcome 😄

[@HuskyBlueFire]

Just did this for our build, warning to anyone going into it, our fuel sender unit was not the same as this one, we had to heavily improvise to make it work. Our blanked connection had no tail on it to connect onto, and the lower cup structure wasn't as open to drop a line down into. Try to find out which sender you have before buying parts. Overall very helpful video to get a good look under there before getting into the job. Thanks.

[@FreedomStrider]

Thanks for sharing, fuel tanks and parts can and do vary from model to model. We are glad that you managed to make your fuel tap work 🙂

Buen trabajo 👍

[@FreedomStrider]

Thanks ☺️

[@ttirrell]

Good job guys. Curious how your heater loop works. Looking forward to an update

[@FreedomStrider]

Us too, it's coming soooooon 😉

[@studios696]

Get your boy some eye protection for that overhead work ❣️

[@FreedomStrider]

You know, I do keep chasing him to put his goggles on, but he is so determined and focused on the job that the numpty forgets half the time anyway... maybe I should glue them on his head 😉😂

[@GuitarsNBikesNBits]

Hi great work, fitted many of these units onto boats so was just curious, generally you did well except for one glaring safety issue, getting under any vehicle that only held on a jack, no no no!

[@FreedomStrider]

well, can't argue there 😅

[@Joop3000]

Good explanation! By the way, did you Notice which color is the fuel return line? I notice that one is marked blue, but i cannot find anywhere what this means.

[@FreedomStrider]

I'm afraid not, didn't see what is the return line

[@user-kl4ju7iw5b]

Where did you get the reducer pipe for your fuel line think it was the 3/8 to 2mm

[@FreedomStrider]

It actually came in our heater kit, from a company called 'Mellor Online' - it is very difficult to find online but if you email them in sure they can do a piece for you :)

[@roberthook9768]

Jobs a good un !

[@FreedomStrider]

Thanks

[@kevinthepilgrim5441]

Great work and well researched. Just a polite suggestion to wear safety gogs when working under the van I wouldn’t want to see you in A&E.

[@FreedomStrider]

Yes, we did wear them sometimes thought they sometimes made it difficult to see so it's a bit of a coin toss but you are right 👍😊

[@nabarnes]

6:14 - How on earth did you get at the top of the fuel tank at that angle? I did mine yesterday and ended up clamping pliers to pull and still managed to take a bite out of my thumb knuckle trying to get to an angle I could squeeze those f*****g buttons together. Did it in the end! 7:46 - Luckily I had watched this video a few weeks ago and bought a strap wrench in preparation - it made undoing that black cap a piece of cake, so thank you for that!

[@FreedomStrider]

Good question... I don't quite remember how that magic angle happened, I'm fairly sure that the cardboard boxes helped it. Sorry about your knuckles ☺️ Well done for having enough determination to finish the job 👏

[@kevinmulligan9055]

I'm watching this as I'm gonna do same for an onboard generator. As I can't get red diesel no more it makes sense to get rid of the onboard generators fuel yank. Only issue is a generator hàs a return line so I'm wondering if this is possible with a return line fitted. Can I drill and seal the top of fuel tank with the return line. Anyone done this

[@FreedomStrider]

Check the top of the tank (not in the lid) some tanks have an extra point on the tanks for this. If not, if you seal it up, I don't see a reason why this would be an issue, not sure what pressure the fuel tank is under?

[@kevinmulligan9055]

@@FreedomStrider cheers. I've looked online and found stainless steel inlet/outlet connections. If I take sender unit off, drill holes and put these in, they come with rubber gromits, and put some high pressure sealant that don't react with fuel around em I should be able to try these

[@sinajayne]

Great video, thank you 👌🏼 What auxiliary fuel line did you buy or did it come with your kit? Thanks 🙏🏻

[@FreedomStrider]

The blue pipe is the fuel line, and that came with the kit... It's a 2mm pipe internal diameter.

[@32eoin32]

Those p clips, how did you attach them to the frame? Self tapping screws? Did you use any rust prevention?

[@FreedomStrider]

We drilled a hole, cleaned and sprayed anti-rust primer and then used metal screws to attach the clips. Alternatively, you can use zip-ties if you have the appropriate hooking spots (but that is just not always possible). 🙂

[@32eoin32]

@@FreedomStrider thanks. Just 1 more question, that connection from the tank to the 2mm plastic hose; that's 6mm to 2mm? Or no? How did you get/make that?

[@FreedomStrider]

If I remember correctly, it was 6mm ID to 2mm ID, and there was a little piece that came in our kit for this. You can alter a piece of 2mm ID rubber fuse line, and dirll out one side with a 6mm drillbit so it would fit (www.melloronline.co.uk/Heater_Installation_Accessories_/5170/Webasto_Marine_fuel_hose_5mm_ISO7840_-_6cm_Length_to_fit_14mm_hose_clamps_.html), hope this helps :)

[@ajaysmobilediscokaraoke102]

What size fuel line did you use the black pipe please

[@FreedomStrider]

The blue fuel line was 2mm ID (1/8"), and the black rubber hose going into the fuel tank was 6mm (1/4").

[@UrbanVanlife]

who ever left that 1 thumbs down , please go back to licking windows and eating crayons , you sad sad little person

[@FreedomStrider]

🤣🤣🤣

[@Andysouthcoast]

Great Video, at 1233 where did you get the reducing connector from, that goes from the 6mm tank fuel line to the 2mm heater fuel line? Thanks

[@FreedomStrider]

Would love to say I remember but I don't - I think we actually drilled out some standard hose that fitted the 3mm fuel line to fit the 6mm port. I did see this in our saved link box: www.butlertechnik.com/eberspacher-reducer-tapered-id-hose-connector-6mm-to-4mm-251888800102-p2281 but it's way overpriced for something so simple.
