WVO Fuel Line Specs?

[Adam]

OK, I just got yelled at by a Lordco parts desk guy when I tried to buy some fuel line for my WVO conversion. He flat out refused to sell me the same fuel line I'd bought previously to run WVO and coolant through. I finally talked him down and promised not to hold him responsible if it messed up my engine. He went so far as to make a note of it on my bill saying that I was using it for an unapproved purpose. I appreciate that fact that he's trying to warn me, but he was a bit of a dick about it. So I decided to triple check that he fuel line I bought won't be causing me problems down the road. I'd hate for the dick to be right. I've already run this same type of line for my coolant to my heated filter and for my WVO line.

What I bought was 3/8" ID SAE 30R7. Plant Drive recommends SAE 30R9 for the first 6" before and after the VegTherm, but other than that I don't see the specs for what I should use for coolant, WVO and diesel. Kevin, Josh, what did you use?

EDIT: I just check the Plant Drive site and it says: The line we have used for both SVO and coolant for years now, it is diesel fuel line. Use only for low pressure systems. Meets spec SAE-30R-7. 50' roll. I paid $26 for a 25' roll from Lordco, looks like PlantDrive is charging $40 for 25'.

Adam, I'm living out of a hotel during the week, and since I was browsing the forum in my van had to pop the hood to check. It's the same fuel line specs in there, though I use braided water line for WVO delivery. Also; within less then 10,000 km's and we'll have traveled 100,000 km's on WVO - and the fuel lines in our family deli still look new. And runs better then ever, it's faster then my deli to boot.

I will get tbose pump specs for you this weekend.

Kev - looking forward to the upcoming Courtenay WVO install...

Hi Adam,

The specs on the hose that is SAE 30R7 is that it is made from a nitrile tubing and the SAE 30R9 is made from a Flouroelastomer. The nitrile is fine but the flourel is rated as "suitable" for vegetable oils see http://www.watson-marlow.com/pdfs-globa ... -us-01.pdf. The nitrile as described by most manufacturers is as follow:

At temperatures up to 100C, or with special compounding up to 120C, nitrile rubber provides an economic material having a high resistance to aliphatic hydrocarbon oils and fuels. Different grades are available - the higher the acrylonitrile (ACN) content, the higher the oil resistance but the poorer is the low temperature flexibility. It has high resilience and high wear resistance but only moderate strength. It has limited weathering resistance, and poor aromatic oil resistance. It can generally be used down to about -30C, but special grades can operate at lower temperatures.

Flourel on the other hand is described as follows:

This is a family of rubbers designed for very high temperature operation. They can operate continuously somewhat in excess of 200C depending on the grade, and intermittently to temperatures as high as 300C. They have outstanding resistance to chemical attack by oxidation, by acids and by fuels. They have good oil resistance. However, at the high operating temperatures they are weak, so that any design must provide adequate support against applied forces. They have limited resistance to steam, hot water, methanol, and other highly polar fluids. They are attacked by amines, strong alkalis and many Freons. There are standard and special grades - the latter can be designed to have special properties such as improved low-temperature resistance.

I think that the Lordco guy was being a dick about it. He is probably one of those guys that if anything new, interesting or different is brought to his attention, he needs to act like an expert and shoot down any idea that comes his way. If he was at all open minded he would have looked into the possiblities and created an "alternative" customer. I love it when people come to my shop and bring a new project with them. If I am at all concerned with the compatability of the product I am selling and their "application" I explain why and alternatives. But in the end it is their money.

As for the WVO install Kevin, next week I would like to get together with you. Maybe Tuesday, later afternoon. I will PM later.

Adam, good work on the lines and such. You are almost there.

Adam,

I used the SAE 30R7 and so far so good....

Sean, Benn here from Cumberland.. How did your WVO install go? I have been stocking oil but have been too busy with the shop and ordering Vehicles from Japan. I have 3 Delicas and a Pajero coming over end of Nov. You know anyone looking for a Super Exceed, let me know. It will be for sale at the end on Nov for $10,900.
Post a few pictures of your install when your done so I can see how you fit it all in.

Cheers,

Benn
