Fuel system parts question...

I just ordered a return line kit today...not the one specifically for the turbo, though. I figured that for the $15+ difference, I'm gonna go ahead and order some Viton O-rings and some Buna-N hose I found that's supposed to be very good for veggie oil, since I may try that stuff eventually.

Now, the question I have is about tees. What materials can I use for tees that will be compatible for veggie oil? Looking on McMaster, when you look up barbed fittings it gives you some options as to what you're using the tee for. If you select "Fuel" it gives you acetal plastic tees. If you select "oil" it gives you plastic, anodized aluminum, and stainless steel tees.

Would the acetal plastic hold up with veggie oil? I ask because those tees are $1.60 each, vs. $6 each for the aluminum or stainless steel.

I think they will be fine.

Veggie oil is not what causes the damage to fuel lines and stock O rings, the biodiesel in strong concentrations is where you start having trouble.

I bought one off ebay.

Dave, Mcmaster-Carr has a chart of hoses on their website abd what materials they can carry, with a rating of A, B, C, D. There is one type of hose that's rated an A for diesel and a D for veggie oil, whereas the stuff I'm looking at is A for diesel and A for veggie oil.
