Clark's sells a kit, but the electric is not the optimum way in my opinion. I would swap out the pressure switch they supply with a PS64 pressure switch. That way you only have one oil pressure switch in the system.

Theirs adds one for pump operation and keeps factory for indication on dash. PS64 switch combines both functions.

Can I use Cunifer lines for fuel? Much easier to work with than steel if they are suitable.

Also, who knows the source for a small air filter for the top of the crankcase vent tube? I am running single K&N filters on the carbs and I hoped to keep the PCV tube functional. At the moment, it just has a cap on it.

Capping is not good, pressure can build up and force oil out of the dipstick tube.

However, the little filters look nice, but allow vented gases into your heater sysem. There are pics on the site that show how people routed the PCV tube to an air filter - your best bet.

On my Cunifer lines they are stamped Brake and Fuel.

Steve sez: Not only do the fumes enter the heater
system into the cabin of the car BUT a fine mist

of oil gathers on the fan shroud around the filter.

It is so easy to plumb to both air cleaners and use
part of the PCV vent tube with the jet orfice to
the balance tube. Engine will breathe as it should.

Look at Mark's (solo2r) engine pic in this thread
for very nice plumbing and detail.

I have the entire PCV (?) tube present. I plumbed the small orfice nipple to the balance tube as normal. I just don't know exactly what to do with the end of the large tube. Not quite clear in the photos if it covers my issue/question.

Bob you "T" from the end of the tube to both small air filter units. Just cut the PCV vent tub to length or shorten and weld the vent tube. There have been lots of pics here showing nice plumbing.

Steve, My individual air cleaners do not have anywhere to plumb the vent line to. They are attached to the carbs by an integrated rubber collar. Do I have the wrong air filters?

Also, what about venting to the outside with a hose? Like the early engines had.

Bob... how tall are the rubber collars? Drill a hole in them!

Bob, you could do that.
Many people on here have.
But it is not optimal, nor does it look good at at.
If you have any degree of blow-by then every time you accelerate, the guy behind you will see a puff of smoke!
Most cars with a road-draft tube are front engine so the smoke dissipates before it reaches the rear of a car.
But our Corvairs, it is all right there for everyone to see!

Bob Matt has shown the fix, fittings into the rubber hoses.

Mel is correct about blowby into the open. If you find an area
with emissions you run the risk of being ticketed for visible
pollutants BUT worse is the showing your Corvair makes to the
public by having the blowby vapors around the car.

This photo may help to explain my situation. There is no place large enough on the K&N filters to attach a hose from the blow-by tube. Should I connect it to the cross over? That seem counter to having the orifice hose attached there.

Some people make an adapter to sit between the filter and car and rout the hose there. Running the large opening to the vacuum balance tube won't work.

I'll have to make that mod after the race weekend. I hope the engine compartment doesn't get oiled badly.
