What are the best fuel lines?

[SouthcoastAus Biofuels Forum Newbie Find all posts View Profile Close SouthcoastAus]

I've been thinking about fuel lines to run in my set up between pumps and heat exchanges, knowing that the oil is going to be pretty hot, I'm looking between polyethelene hose and what they call trucker hoses from the hydraulic shop, these are braided with stainless steel and have a high tempreture rating, but cost a fortune $100/metre. I've looked at plex lines but they are too stiff for the bends I need, regular polyethelene hoses might not handle to tempretures , deteriorate and leak at joins, I'm wondering what other wvo uses are using, or what problems you've had, any recomendations would be greatly appreciated


If I could also get any info in relation to oil tempreture, can the oil in the system get too hot and effect the solenoid valves or pump?

Under no circumstances use polyethylene or polypropylene. These will soften when hot and will not take the pressure over time. Normal fuel hose made with an inner lining of nitrile rubber is ok for vege oil, 3/8" hose costs about $8/meter. Some people use the semi clear PVC braided line but that will harden over time when subject to heat.

Has anyone seen the purple poly tubing that is used in boiler or hydronic heating scenerios. I would think that would handle the heat and give enough flex to run from engine bay to tank for hose in hose application??. Any thoughts

Re: What are the best fuel lines?

if you can find
Polyurethane
Rated for temperatures from -65 to 220 deg F. -54c to 104c
Excellent resistance to Bio-Diesel so it would be fine for vegetable oil
I am using it between my fuel filter and the IP on my VW.
It is clear so it gives you the added benafit of being able to see any air leaks in the system. It is avaible in most motercycle shops. hope this helps

I suggest to my Vegiecars customers, that they go to a fluid drive supplier such as Pirtek or Enzed and talk to them. I get my hoses from Pirtek, with a fuel line rated to about 120c being about twice the price of their ordinary fuel line, but not much more than buying from an auto shop.

Re: What are the best fuel lines?

Most houses are now plumbed up with a thick walled black poly ( Romac i think its called ) and it uses a special crimper for the joins it is used for both hot and cold, would this work for the outer hosing for a hose in hose set up. More flex that copper and more robust than rubber.

Mate , Get all your fuel hose from Clark Rubber. This very same hose is sold there for $5.45/meter. I checked at ENZED and it was $17/ meter.

Cheers.

Re: What are the best fuel lines?

What is the best diameter for fuel lines? Is bigger better? Can all the lines be the same diameter?

Thanks

I went to supercheap the other day and got some 1/4" line for $11.95 a meter then I spotted it at the local Clarks for $6.95 /M off the roll and the exact same stuff.
They also had the regular clear plastic line and the reinforced variety cheaper than other places.

Hi urvey when replacing fuel lines replace with the same size hose..... smaller simply will not fit and larger hoses will leak
Quite simple replace same for same size.

Re: What are the best fuel lines?

If you are adding fuel line for a veggie conversion, then a larger internal diameter will allow for a lower resistance to flow, especiallt in the unheated fuel lines and long runs. You can get the hose barbs to suit and design your system to handle these hose sizes. Where the hose barb is a fixed size (eg Pollak valves and IP), step down to that hose size at a convenient location (eg filter)
