>>>where do i drill hole for diy vented gas cap<<<

[1BAD65]

CARB IS FLOODING AFTER REPLACING ALL FUEL LINES AND MECHANICAL FUEL PUMP

TANK HAS 2 LINES OUT AND VENT

PUMP ONLY HAS 2 LINES IN (FROM TANK) AND OUT (TO CARB)

BROTHER TEXTED ME TODAY SAYING CARB FLOODED BADLY - GAS EVERYWHERE

TOLD HIM TO CRACK OPEN THE GAS CAP UNTIL I CAN GET OUT THERE TOMORROW MORNING

I SEARCHED ON HERE AND FOUND ALLOT OF GUYS JUST DRILL A PINHOLE IN THE GAS CAP TO TRULY MAKE IT A VENTED GAS CAP BECAUSE THE STORE BOUGHT "VENTED GAS CAPS" DO NOT TRULY VENT BUT HOLD 3psi !

DOES ANYONE HAVE A PIC OR DIAGRAM SHOWING WHERE I AM SUPPOSED TO DRILL THE PINHOLE?

THANKS GUYS

I WILL CHECK BACK TOMORROW MORNING

If the carb is flooding, you more than likely have a sunk or stuck float. Randomly drilling holes in things isn't going to fix it, and get rid of the caps

Not shure on the gas cap drilling ..but I would check the carb float bowl and check that the needle is seated properly and adjusted right..

Yep x2 my slow spelling. .

I had a similar problem on my 67..
The cap installed by the PO was unable to vent adequate pressure, resulting in gas forcing itself into the carburetor and eventually into the crankcase.

I used a NAPA cap (p/n: BK 7031220) to remedy this. It worked like a charm! No more contaminated oil or carburetor flooding.

Hope this helps!
