[sdwarf36]

I just turned 70k miles on veggie yesterday!

plaggy tank & plaggy pipe it is then 

cheers for all the good input

[macka]

please define plaggy so I can use it in proper context

Hes a Limey..so that might be an actual word there..but Im guessing its a case of "predictive" texting.

*Limey is as derogatory as being called a Yankee...and I love limes..hate scurvy..and love my island dwelling vw diseased brothers*

Mr Bandit,

I have one of those exact tanks, unused, if you want one. Are you near York at all? If so Im there on Monday...

Cheers, MM

ive got my eye on one at the mo

Plastic seems to be the best bet..  Just make sure that if you use something that wasn't necessarily intended for this purpose that it can take the heat.  First time out I used a 15 gallon plastic drum turned on it's side..  Although never a major problem, when it got up to temp it would get soft and slide about in it's mounting straps..  I probably never would have had to change it, but the thought of 10 or so gallons of hot WVO flowing from behind the back seat always worried me a bit..

[tunedbandit]

true,,,what a mess that would be

dont think you"ve every get rid of it

I actually imported some of those tanks from dieselveg. The nicest, thickest plastic tanks i've seen yet.

Most of the plastic tanks I've encountered lack proper baffling and venting.  Lack of baffles is really noticeable with a 30 gal tank half full  transverse mounted in a Mercedes.

Lack of baffles is really noticeable

Indeed!!!   It's the one thing I have neglected on all 3 tanks I've made now Even with the 8 gallon tank in the spare tire well I can feel it slosh..   THe 15 gallon drum was horrid..  Had I not coated the inside of the tank in both cars with the Eastwood gas tank sealer (essentially plastic coats the inside of the tank) I'd be temped to break them open and weld something in there..

Speaking of venting, some more food for though..   I guess if you have something with a normal ole trunk this isn't an issue, however since all I ever seem to run is MK1 Rabbits the tank is basically in the passenger compartment..  Eventually I got sick of the smell inside the car (always arriving at places smelling like fast food grows old)..  The latest rig I installed an external filler neck behind the license plate, and vented the tank though the cap.. No moer worries about spilling inside the car at fillup!  Took care of the smell but now with all the heating and cooling I tend to draw a lot of moisture into the tank.. Especially in the lovely damp spring weather..  For now I went back to running a sealed cap and venting back inside the car..  I fashoined a foam filter like thing for the vent hose and chukked it into the quarter panel..

For those of you who are cheap like me and end up building a tank that costs 3x as much as one you could have bought, I've been looking at this PVC tubing that they use for heated driveways and radiant floor heating..  It must be able to transfer a reasonable amount of heat since in it's normal applications that's what it does..  I think it's rated for something like 300 psi @ 300 F...  Might work nice for the in tank heat exchanger...

It is definitely worth however much effort it takes to make filling happen outside the car.

PEX tube?  it should do fine, just be sure no part of it is exposed to UV.

[maxfax]

It's wonderful to be able to back into the pump, flip the plate down, and grease 'er up..  I just snagged a fill nozzle from a fuel pump for my pumping station so it'll shut off before overflowing things..   

Venting externally, however, wasn't as much fun of an experience.. I spend the better part of a month trying to find the source of the water...  The current setup seems to be working okay now..  The car still has a bit of that smell going on, but nothing a pine tree can't fix..   And not near as bad a basically having a hole at the top of the tank..

This tubing I spoke of reminds me a lot of PEX but it has thinner walls.. It feels really flimsy, but according to the specs it should hold..  I'm assuming the pressure and temp specs are for just the tubing, and not for the tubing encased in say concrete..  I'll have to look into what they call it next time I'm buying house crap..

I have PEX  wrapped with insulation stuff for the coolant lines back to the tank, and for the fuel lines too...  Works spectacular... One just has to remember, when using PEX for coolant lines, to use the inserts inside the ends of the tubing with compression fittings..  Ask me what not to do, I've probably done it..

PEX comes in two styles, one that is rigid, and one that is flexible.

the rigid stuff acts alot like PVC, but is a great inert plastic, and the flexible stuff has much thinner walls(while being made of the same inert plastic) and can be bent pretty easily around some pretty tight corners.

I like both, much easier to use than any other tubing system, it can all be assembled without heat or chemicals, and can even be disassembled later if you use the right couplers.

I would not hesitate to use it in a veg fuel system(if I built one, which I have no plans to do so)
I do have plans to use some for the plumbing of an air water intercooler in the fall.
