Title: LPG filler hose length
Post by: TheBoy on 17 March 2011, 16:22:41
How much do I need?

Teilo says the hole on tank is as near as centre as to make no difference, filler will be in same place as MV6 behind numberplate?

Why bother with a JIC pipe... Just get the correct end to use Polyflex ;)

Incidentally, you can get a polyflex fittings that attach straight to JIC type fittings, although Teilo may not do them

Or, in answer to the question, dunno! What route did/does the pipe take? I assume around the tank? All I can suggest is getting out there and having a little measure

Because I get cold hands waiting 3hrs for the rather thing to fill.  A certain Mr Wood likes to gloat he can fill his very fast (at certain stations), so thats the line I'd like to go down ;)

There are very few stations in the UK where you'll get the benefit ;)

Most of the cheaper ones don't have fast enough pumps... In fact, I don't recall anywhere I've been in the UK with a fast enough pump (apart from where KW fills, although I've never been there)... On the continent, however........

[edit]Oh... And the 4-hole tank fill valve will be faster anyway :y[/edit]

Here's my guestimate...

750mm from Tophat to centre of tank
750mm from tophat to osr corner
500mm from osr corner to middle of number plate


Is somebody with more intelligence than me confirm that 2m is correct?

I have a feeling mine was 2m and that goes straight down through the boot floor and along the tow bar. No chance would it make that run. I had to get a longer one at any rate.

I would probably route the hose  round behind the trim panels, down through the first aid kit cubby hole, out behind the bumper and across to the filler. They don't need to be inside the airtight ducting. :y

Also consider whether you need straight or right angled unions on the hose and filler.

That's 2m all right... But does that allow a little "spare" as well?

Mind you, that should be OK :-/

why doesn't it need to be in airtight duct?

whats wrong with following similar route to the polyflex route on MV6?

The JIC pipe just gets sealed inside a boot at the Tank end and on the back of the filler (if internal) :y

Right, OK, so what route would you follow Lazytinker?

KW's route sounds very good and tidy... Similar to mine (as far as the filler in the rear wing) and would be neat and tidy... Only down side I can see is securing the pipe every 600mm (maximum) as per COP11 and the open hole in the floor, although I'm sure Teilo could chuck a spare boot in the post to seal the hose to a "Top Hat" in the floor ;)

TBH, I would just use Polyflex for the fill and run it through ducting because I'm tight I can't see the point in paying the extra ;)

I think that the spare filler I gave you is for JIC type hose though :y
Title: Re: LPG filler hose length
Post by: Lazydocker on 17 March 2011, 21:34:05
Of course, if you really wanted to make more work you could drop the petrol tank and run it in a reasonably straight line ::)

If you want to use a similar route to the PF on the Silver Bullet then you either still need the second boot or to run it through ducting ;)

Last time I lowered the petrol tank (on Tractor) it was fairly quick and easy, so thats always a possibility  :-/.  Is there room above it though :-/

I was thinking of running it in corregated tube from tank to top hat.


Unclear what gains (or disadvantages beyond it looks more challenging) Kevin Wood's route has  :-/


Kevin Wood - LD has already said he wouldn't use anything other than polyflex, what are your views?

Mine's done with JIC hose but there are so few UK filling stations with a pump fast enough to get the benefit I'd use PF if I did it again, especially with the filler located where yours will be ;)

If mounting it on a tow bar I would probably change my mind again ::)

I looked at routing my pipe round the offside of the petrol tank and found very little to screw it to and lots of edges to protect it from IIRC. Would need to have another look under there to be sure.

You might get away with routing polyflex above the petrol tank. Might need to space it away from the boot floor a little perhaps?

If you prefer routing it under the floor go with polyflex.

With hose you need to know an accurate length and you really need to offer up a dummy length of hose along the route to know that. With polyflex you can wing it and then cut it to length so from a point of view of ordering everything you need before starting the job it has an advantage.

Haven't ever had to live with a system that fills through a small diameter pipe so can't really comment on that.

You also want to tell him if that's what you're doing... He might be able to supply one of these (eGay Link) (http://cgi.ebay.co.uk/Flared-1-2-UNF-LPG-Autogas-Polyflex-Pipe-End-fitting-/250620269742?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item3a5a21d4ae) for the fuel outlet and one of the ones further down the listing for the fill end and filler end... Just for neatness :y

I have... My RR filled one of the three tanks through 8mm copper pipe (the 80L Single Hole Cylinder) and, TBH, I don't think it was any slower filling than my current setup at the same pumps :-/

hmmmm, I'm even less decided than I was before ;D.  Now I'm beginning to think Polyflex, for an easy life ;D.

Does that mean there isn't room for the large pipe above tank?

Only you can decide... But you've got plenty of Polyflex and would only need to buy £5 or so of ends instead of a £35 odd pipe ::)

Like I said, unless the rear of the filler was located within the passenger compartment (including the boot) I would use polyflex without a second thought ;) :y

ISTR that there's only about 15mm at the most :-/ :-/

If you go for JIC pipe and it's too short then it'll be a very short fitting weekend ::) ::)

Yep, no chance of getting the hose above the tank. IIRC, the tank is pretty much hard up against the boot floor, so I reckon it would need dropping a little to fit polyflex.

Sounds like polyflex is the best option. Especially given the cost. Don't think Jeremy ever got round to charging me for the filler pipe. Or telling me where to return the one that was too short. :-X

Re routing, can we not copy the mv6? Ie out of the boot floor screwed to chassis rail behind wheel arch/over drive shafts behind petrol filler and along the back of the cross member? Thought we had enough last time?

Re length I have some left over from last install, which we had available last time but didn't use iirc?

Re fill rate I assumed, possibly wrongly, that a single hole was slower to fill than 4 hole anyway?  :-/

Seems that route can only be used with polyflex, I was hoping to use the bigger stuff, but seems this may be a challenge, and needs the hose to be premade to a precise length...

If going for polyflex, remember you will need a boot to connect a duct on both sides of the airtight box. Mine came with one for one side, and a rubber boot to seal against the filler hose on the other.

Or just vent it with vent hose... This more than covers the cross section required in the COP ;)

I don't understand how you'd seal it at the tank end, though. :-/

When you say vent hose, I assume you mean the convoluted plastic stuff?

Yep... Tank comes with 2 vent "outlets" on the Gas Tight Box as standard, one of which we used for the JIC boot ;)

This type of box:

(http://i173.photobucket.com/albums/w63/kjwood/LPG%20Conversion/IMGP2109.jpg)

The fitting on the right hand side is a big rubber boot that seals to the jic hose. I don't remember getting anything that would seal that outlet to the convoluted tube, although I might be wrong.

I think you can blank that off :-/ :-/

Sure Teilo will sort it ;) Actually... I'm sure I've got a boot that would fit polyflex anyway ;) Or perhaps it was in the "Spares" I gave TB at the meet :-/ :-/

Think polyflex. Tried to call him today, no joy. Got pretty limited phone for next few days, but will try again Monday.

Kit is being delivered in just over a week :)
