TheSamba.com :: View topic - Routing Hoses To A Remote Full-Flow Oil Filter

Sun Aug 24, 2008 7:45 am

With the doghouse oil cooler-equipped engine now installed in my '64 Bus, I have decided to place the remote oil filter behind the left rear wheel, with the filter mount bolted to the frame support for the bumper bracket.

It looks to me that the most direct routing of the hoses from the oil pump to the filter and back to the crankcase oil gallery passes them between the intake heat riser pipe and the cylinder head. The heat of these objects makes me a little nervous.

I suppose I ought to get steel-braided oil hoses that would stand up to the heat better than rubber hoses.

Any comments from those with experience mounting remote oil filters and routing the hoses thereto are welcome.

My remote cooler is half way along the bus between sill and chassis and the hoses are simply run along chassis with filter under battery tray and pipes straight to the full flow from there

I have my oil filter behind the left rear wheel as well.
I header wrapped both the header and the oil lines to insulate them from the heat.
I also used hydraulic lines. No issues.

Thanks to both of you!

Riff Raff, please define header wrapped.

Also, you are using hydraulic hoses, but are they rubber or steel braided?

And lastly, I came across a website yesterday that said that steel braided hydraulic hoses require a different kind of fitting, but no further information seemed to be available. Does anyone have experience with using steel braided hydraulic hoses for a remote oil cooler or filter?

Header wrap is a non flammable fabric wrap - looks like burlap - that is used to wrap exhaust components to reduce the amount of radiant heat they eminate.
The concept is that the exhaust heat will be rejected out the tail pipe instead of along the exhaust pipe route. Most engines utilize the heat of combustion at the ratio of about 1/3 into usable energy, 1/3 out of the water jackets (or, in our case, cooling fins) and 1/3 rejected out the exhaust, so there is a fair bit of heat to contend with.

The hydraulic lines I used are not steel braided. I suppose exterior steel braided hoses would reflect more radiant heat, but I would header wrap them regardless. I don't know if exterior braided hydraulic hoses will require different hydraulic fittings.
The thread pitch is not unique to hydraulic fittings though, so you can have the lines fitted with hydraulic fittings that will thread right into your block on one end and into the filter housing on the other.
I got swivel fittings on the filter end because I thought I would want to unscrew the fittings to pull the engine. Turns out it is easier (and cleaner) to unbolt the filter housing off the frame and remove the engine and filter assembly intact.
Swivel fittings are still required to plumb it in initially, but not for engine removal.
Hydraulic hoses and fittings have the advantage of being designed for high heat and high pressure applications, so the lines will not degrade because of high oil temps and the fittings will never blow off.

Can you post pictures of your set up please!!!!! :D
