What you guys think of my air filter idea?

Post by flatfourfan »

Since I've had my motor on my bus, I've not really shined to the K&N style cone filters that were fitted to them, one sits slightly off-centre and has to be screwed onto the carb in order to get it on. Plus they look too sporty.....lol.

So I did some thinking and was trying to get something more stock looking, until Armand suggested an idea to me that I'm half miffed that I didn't think of it myself in the first place as it's so obvious.... :oops:

Use two round style oil bath filters. This way you get that vintage look of the older worked motors, but also probably the best filtration that you can on the vw motor. Of course I'm going to be re-painting a few items in the engine bay to go along with the theme, (alt backing plate as well as coil will be painted black).

Did a search on the Samba and came up with a few really nice looking engine bays.......but this one got my attention.

What you think of the idea?

Never, ever fit an inline fuel filter inside the engine bay above the dizzy unless you want to get rid of your van in a most spectacular way......

Fuel filters on my rides are fitted behind the left rear wheel where the fuel line enters the engine bay through the firewall.

Just a tip. ;)

...and while we're on it, replace all fuel hose in your engine bay AT LEAST once a year, twice if you're extra cautious. :mrgreen:

The first accessory fitted to any old VW should be an extinguisher - a big one. :D

That's a nice looking air cleaner set-up; very stock looking.

On closer inspection, though, I don't think those are VW air cleaners. All VW oil bath air cleaners I have seen have clamps holding them together, not wing nuts as those have. And the clincher is the instructions on the stickers refer to K&N filters (always read the small print)!

Do you know if early Beetle oil bath air cleaners will fit on 32PDSIT carbs? I must dig one out and check ...

And on the subject of fire prevention (this should have its own thread or sticky):

The best fire protection you can give your ACVW is a solenoid cut-off at the base of the fuel tank. There is a gravity feed of fuel to the engine compartment, so essentially unlimited fuel to the fire. Even after dowsing with a fire extinguisher, fresh petrol on hot metal combusts almost instantaneously.

The solenoid allows you to shut off the fuel supply if you notice an engine fire, so when you fight the fire there's no fresh fuel.

And it doubles up as theft protection. If you activate it with a hidden switch then if someone drives off in your car they only have the fuel in the carb and with any luck it'll die in the middle of an intersection and attract attention.

Yeah fig I noticed that the *oil filters* that I posted seem to be cases for K&N filters. I've managed to pick up two older style round oil bath air filters that I'll be looking at modding to get them to work. The intake arm that goes off to the side will have to be cut off and the hold welded closed as it's going to look pretty kakky with them.

As for the fuel lines, I only use HP lines, they may cost a bit more than the cheap rubbish, but they're good for much longer and are steel reinforced as well.............bonus.

I've started working on this project already and should have some pictures to post up soon. Just need to find someone with a mig welder who can neatly weld up the holes for me and install a pipe for the oil breather..........

Stay Tuned.

Flatfourfan, I was also thinking about twin oilbath aircleaners. I was considering various engine options for my 1970 Baywindow 1600 sp.It is very reliable at the moment so I decided to leave it as it is for the time being. I use my bus to tour to remote places and love dirt roads (Namaqualand, Namib desert, etc). Most upgrades would necitate twin carbs (although I prefer single carb setup) and , yes, dust is one of our beloved aircooled flatfour's biggest enemies. My dream engine would be a 2027cc (90.5x78.4) engine with Nicasil Cylinders, brand new Auto Linea casing, forged pistons,conrods,crank (8 doweled counter weighted), full flow oil system,etc. Such an engine would need twin carbs unless one can fit a decent fuel injection system. But the setup on your pictures looks very neat, I will definitely make a note of it.

As for the fuel lines....

if you are referring to HP lines as copper or stailess lines.... you need to put in at least one flexible piece of hose to take up vibration and the resulting stresses.
I know, its been done before without the flex hose, but it wasnt right then and it still isnt right now. I have seen a copper fuel pipe (on a ship) crack and leak because of the vibration which caused it to work harden and become brittle.

Fig, the Beetle oil bath air cleaners will fit on 32PDSIT carbs, but you will need to cut the T3 mounting set up off the top of the carbs, the dia of the top of the carbs and the oil bath air cleaners are similar about 52mm, longer SP type inlet manifolds will help clear the fan shroud it will be more of a fidlly job if you use the shorter T3 manifolds.
Gary, your idea is great, but it's a bit complex. Firstly your carb dia at the top is about 57mm and the filters are more like 52, your 34PDSIT have an idle circuit which is blocked off on your left carb which sticks out about 35-40mm above the carb which will cause a problem when fiting the filter, again the longer SP manifolds will help ths setup a bit as everything sits higher.

The fuel lines I used are intended for use on Fuel Injection systems and they can take up to something like 20Psi, I have never had a single faliure using this type of pipe, more than enough for a little mechanical VW pump, the weak area in many cases are the cable clamps, when they get over tightened they will fail then a leak will just be waiting to happen.
