According to the '74 service manual, you have a vent on your fuel cap and just one hose to the intake with one little overflow bucket or something in the path.

 

For some reason, my car has a "wagon" setup in terms of the ventilation. Although mine doesn't have the fuel cap vent, its actually a different fuel cap all together so its hard to find one (I didn't want to drill it for that reason).

  • OMG! FINALLY! She will live again!  THE HOLE.... IS GONE! (more photos to come soon - i just opened the box, crappy phone pix!)       Now the fun begins. 

  • SEAT PHOTOS!   Again, seats are from a 1982 Mazda GLC. They were from the original owner, who'd removed them from his car when new to install Sparco seats. Sat in his basement for 30 years waiting

  • Horns work!  (BEEP BEEP you've been warned!)   click here for video       Engine will be back inside of the car TODAY

Kosta, i doubt that the fuel cap actually seals the tank 100% so run the system as you said but check to see if the fuel pump shuts down when it gets to pressure, but if the carb has an overflow pipe, route that back to the inlet side of the filter

The carb doesn't have an overflow pipe. I have seen other IDF's with overflows, but those were only ones that were equipped on specific vehicles from the factory. The carbs themselves aren't sold with them.

 

 

Anyway, my crown jewel is ready to go, just waiting on cylinder heads to come back from the shop!

Hummmm, I been wanting some MSD myself.:banana:

 

Edit: BTW, if I understand right, I'd want to run a return line at the carb with no regulator. To the tank would even be good. Hummmm?

Don't know, thats what I've been trying to figure out.

Kosta,

 

Like you had in #2 with the fuel return. The venting is all seperate from this. I would have to see/know what's on the other ends of those lines in the tank. That would help.

Looking as to where the coil and pump is situated you not carring the spare under the bonnet

What spare? :lol:

This is a Hitachi 4 Bore fuel inlet. Fuel in big one, the small one is drilled like a large carb jet on the return line.

With something like this, and roll-over protection to shut the fuel pump off If I ever do that, takes care of those lines. Fuel return near the bottom of the tank is my preference.

Been busy while waiting for the heads...

I think the tach location needs some work, but I'm not sure exactly what to do about it.

 

Luckily the original speaker hole was EXACTLY the same size as this tach, so I just modified it a little and got it to fit in there rather well.

 

The horns I built some simple brackets for (just thick sheet metal drilled with the right holes) and they fit good too. I actually saw a photo of a car in japan with horns installed like this too.

from memory isnt that where the original horn mounts

Does anyone have a spare "overflow limiter" from a later model Subaru? Its a tiny thing next in line to the little evap tank in the fuel system evap.

Steve, if you're having problems finding info for the car, I have a few of the FF1 FSMs at my house.

  • Author

I have all the FSM's. The "overflow limiter" is on the later cars instead of the little valve thing that is on the FF-1, which I obviously can't replicate properly. But with one of the limiters from the later cars, I can duplicate the system from those cars and it should work fine.

 

I think its just a two way valve. If I can figure out exactly what it is, maybe I can get something similar from Napa/Kragen/etc.?

Emergency!!!

 

I need a set of the 1400 Flywheel double washer thingies for locking down the flywheel! The 1100 ones don't match up, nor do the other 1600 ones I have!

 

I need them ASAP if anyone has a set! (4, one is slightly longer than the other 3)

Got back the camshaft and the cylinder heads :)

Yes, the heads are shaved 2mm to fit the Weber manifold!

^ drrooooool :slobber::slobber::slobber:. Man that looks nice! Did they port them at all for ya?

If no luck with the lock tabs, try loctite or if you are patiant make a set

Cheers Thierry

Hooray!!! Thanks again mark :)

 

Got the valves adjusted (I'm pretty sure correctly) and a few other small things done.

Had a small idea. What about reversing the oil filler tube?
