same here, just a red wire to splice in.

and the draw straw airdog now includes is slightly different than the vulcan drawstraw. it uses the same anodized aluminum fitting/grommet but in silver instead of green. the main difference is the threaded fitting that the plastic straw goes into. airdog supplies a cheaper brass fitting from china. the vulcan fitting is beefier also vulcan pre-assembles the drawstraw using diesel thread sealant. its not a big deal, just a small way of cutting costs slightly.

 

**Update**
So after some time driving this set up I had become very annoyed by the fluctuating fuel pressures at 1/4 tank..it was like a switch soon as the needle touches the 1/4 tank line on the gauge...I would start to get 0 psi readings at "take off", slowing to a stoplight, or going down a hill or up...it drove me nuts!!!!! the whole point of the system is to keep air out....
so I decided that I would maybe save some cash by moding my stock fuel canister instead of buying a liberty canister....it went pretty well...here is what I did...
this First pic is of the parts I used to mod it...the small black cap was NOT used..

my plan was to have the stock engine return stay where it is..then I would plumb a 1/2" pick-up and the a 1/2" return for the AD150 ALL inside the stock canister...my thinking is the Airdogs return fuel will help keep the can full even when the tank gets down to 1/4 tank.
so you have a..
stock engine return line
Airdog return line
Airdog suction line
all plumbed into the top of my stock 06 canister.

in the pic above you can see the BOSS O-ring fitting 4 AN(3/8") that I screwed into the bottom part of the canister..I was going to tap some threads into the plastic BUT the BOSS fitting screwed right in...and the o-ring even ended up seating down into the canister bevel...it's like it was made for it!!!!!...then you use a 3/8" push-loc with a 4AN swivel..
I used ether hose...when I asked about a fuel line that could be submerged they told me that I should NOT submerge regular hose like what comes with the airdog...it needs to be rated for submersion IN diesel fuel...they said the ether hose would be perfect for that.
so you can see the clear ether hose that I plumbed up to the engine return port..all this does it help drop the fuel right into the canister...just like stock.

here you can see I modded my Vulcan drawstraw so that I could put a bigger piece of the ether hose on the end and use it as a FLEXIBLE pickup...the hose fit really tight but I put a clamp on it just to be safe...I also zip tied the stock fuel pump wires out of the way.


this is a shot of the return line with a hard line attached to help direct the airdogs return fuel back to the canister. (note the extra pick-up holes I drilled in the bottom)

the zip tie on the big clear hose is to help keep the hose inplace..I would hate to have it move and block the fuel gauge float movement..



I tried to get the pics the best I could...here is what I did....drilled 5 more holes in the bottom of the canister..I did not get a pic of it but there is a small screen on the bottom of the canister just take a small screw driver and pop it off to access the bottom for drilling..I drilled the holes about the same size as the stock holes..I think they were 21/64 or something??
there was NO WAY to retain the factory flapper valve set-up..like what the liberty can uses..but I am not convinced it is needed at this point...

as you can see you have to mod the top support grids on the canister in order to make the vulacn drawstraw fit...I used a 90* angle grinder with a course 3M scotch brite pad(worked really well!!) you also have to do the same to the bottom side...

the pick up tube was kinda tricky to get set....I cut a small "V" out of the corners to make sure when it was compressed by the springs on the canister that it did not close off the flow or kink any lines....the ether hose on the engine return line keep wanting to kink so I had to preload the springs buy making the line a little shorter...not a big deal...but you need to make sure it is not kinked other wise you could have some issues on your hands.

So hows it work??????
I LOVE IT!!!!!!!
I have super solid pressure now before it was all over the place at 1/4 tank..but now on the same hills it was fluctuating on, it now holds 17psi..the only time I was able to get the FP to drop was on a big hill while stopping...and it did not go to "0" psi like it did before it went to 9 psi and then bounce right back to 17psi...I LOVE IT!!!! before on the same hill the FP would go to "0" then it would bounce up to 17psi and then back to "0"...you could actually watch the fuel sloshing buy the readings on the FP gauge.
so now I have ALL my tank capacity back and I dont have to watch the FP going all over the map...I am really happy with the mod so far...I even filled the truck to just 1/4 tank to make sure I was good...and I am.... I can take it all the way into the red on the gauge now with NO "0" psi readings!!!!!

note...make sure you blow out your stock fuel supply line when you finally disconnect it, other wise it will leak all over the tank and make you think you have a tank leak...( I almost pulled my bed back off..before I realized where the leak came from)


I think I covered most the install???? if you have questions just ask.
there is a lot of cutting in this mod...you pretty much have to gut the factory canister....

I spent $8 for the hose and the fittings and also had to buy a new pick-up/drawstraw
I am happy with the results!!

you would have to buy the same drawstraw to mod a liberty canister to work with a AD150...so this does save some cash..if you have the tools to mod yours..

 

Nice work ******. I may copy this in the future. Mine only starts to hit 0psi at about 1/8th of a tank, and only when I am stopping or slowing down. But 20 miles or so after that, it starts hitting 0psi on turns & everything, and it will stay there for like a second or two.

My tank vent mod is done just like yours, (copy catted ya") and it is great. I noticed the other day that after a fill up, by the time the needle is off the right peg and in the center of the first "full" mark, I had gone 94 miles.

I want a bigger tank some day. If I do it, I am copying this too.

Thanx.

 

As always a great write up Mark!!!

 

how did you patch the hole in your tank from where the drawstraw used to be?

 

I used a old school airdog bulkhead fitting...(the old grey one)

 

pic.....it now has a real steel AN cap on it not the plastic one pictured here...

 

Cool, nice work Mark!

I'll be in touch for more info when the time comes to do mine.

What is that rigid looking hose, is that what comes with the Vulcan?

that clear stuff looks like RV water hose...

 

I used the rigid line on the airdog return...I wanted to make sure the fuel was dropping into the cup/canister so I used the rigid stuff to get it down there...

Thanks for the comments guys!!!! I am really happy I did this mod so far..I was really getting annoyed by the crazy FP readings before
now it stays soild...hardly comes off 17 psi....

 

I had mine drawing out of the stock canister and there was not enough fuel in there once I got below 1/4 tank to keep the FP up, so I went back to the draw straw and have not had a problem with it yet. I did not plumb the Air Dog into the stock canister though. I guess if I start to get the fluxuating FP again I will consider this mod.

This is true, I used diesel rated hose in my tank, not sumersible diesel rated and it was starting to deteriorate within a few weeks of the install.

 

Wow I guess the AD sucks a lot of fuel up but must return about the same...my FP has been great!!! I have had the best FP readings I have ever had since I changed the pick-up........I am really surprised that the hose was going down hill that fast!!!! I almost used the regular hose with out asking them,,after hearing your results I am glad I did not!!!

 

My Air Dog return does not go into the canister, it goes into the filler neck. It was not deteriating bad, but if you rubbed it it would flake and it was very very soft.

 

yeah that's what I was saying...the only difference between yours and mine is mine has the Airdog return line plumbed back to the canister....Charlie told me before I even installed mine the first time that the AD150 would suck a stock basket dry when the tank got low..I asked him about plumbing the return line back to the canister and he said "I don't know try it!!!" I am very pleased so far.

 

Well I hope I don't end up eating crow on this one, but I have the same hose that is supplied with the airdog submerged in my fuel tank. And it has been that way since new years. Lil' over two months. Guess we'll see.

 

Mark, very nice work and write up with pics.

Thank you for sharing,
