I am looking for some high quality hoses to attach to my catch can that won't collapse under the engine bay head.

What do you recommend?

 

regular fuel hoses

agreed. the crappy nylon reinforced hoses that came with mine collapsed once they got warm... ditched them immediatly for regular fuel hosing. Fuel hosing is build to withstand positive internal pressure, but is also great for negative internal pressure.

 

Theres no such thing as negative pressure... It's called vaccum

 

dennis

ive been running the endyne style breather kit w/ the nylon hoses for ever, and no problems what so ever, and so have a numerous other people i know.

 

Where did you buy yours Arno?

 

a plumbing supply near work.

I believe we have some left over if you want i can check.

any home depot will have it, its pretty inexpensive.

 

What kind of catch can do you have?

 

you could run Aeroquip / Earls if you must haveth the bling.

I use regular fuel hose.

 

I bought some regular 3/8s fuel hose today. I compared it to the bridgestone fuel hose that came with the catch can and the bridgestone is definately more quality. Much more dense with more of the threads(?) inside.

 

Just got back from the track last weekend and the hoses collapsed!

Anyone have any suggestions for heavy duty ones? The ones I ran were regular fuel line hoses.

Could it be the location? I have it sitting pretty far away right next to the driver side headlight where the windshield washer resevoir used to be.

 

how the ****?

well you could try coolant lines
they have more threads in them

are you routing them that they touch a heat source?


i can't understand how you collapsed rubber fuel hose lines

 

The fuel lines got really mushy and soft and as soon as I moved them, they curled up on me.

They really aren't touching anything HOT. I'll take a pic of it when I have time.

 

how do you have your setup routed?

PCV-&gt;catch can-&gt;manifold ?

return line? no return line?

Exactly.

I also filled it completely up this weekend.

1st and 2nd sessions it did not catch anything.

3rd session = half full

4th session = full, almost maxed out

I drained it immediately after the 4th session. On the trip home, not one drop.

 

Maybe your PCV valve is stuck closed?

How can I test?

Maybe your oil temps got too high during the 3rd 4th sessions.


i was chatting with some people who race alot of high out B series motor's and say its very normal for them to use oil, or catch can's to fill up quickly, nature of the best i guess

take it out, and shake it, it should rattle


one thing you can do, its ghetto, but it works pretty good

is clean in out with brake cleaner, just make sure to dry it out good before reinstallation

 

please post up when you find a solution.

my carbing catch can sucks the hoses shut too.....

 

You can blow on it. It shouldn't let you blow. Then suck on it. It should open up. You should be able to do it with a hose attached. Oh and don't do it while the engine is running.

 

3rd and 4th sessions were definately hotter as the outside temps did increase and I was pushing the car a lot harder.

No oil was burned during the session.

How does heat relate to the catch can accumulating more oil? Isn't it really all based on vacuum?

 

viscosity will change with temperature
my guess is that a thinner oil is easier to suck into the can

That logic works for me. Thanks.

yep, try runing an oil with a higher temp rating, RJ. i think was running 50 or something like that
