Here is a repeat of the vent pics for "kirkhull"

I added some comments below.

--------------------

Yes the vent is at the top of the tank under the 

flange. One can use a swivel 90 deg fitting. Some 

have female threads so one has to use a close 

union In any event they are available. Check 

hydraulic supply houses. Check the car nut places 

like Earls. Attached is a couple of pics for an 

even easier way using AN fittings & a straight 

swivel from the hydraulics house + soft Al tubing.

PS, The hydraulic people only sell cad plated 

steel fittings with the AN 37 deg flare.

PPS, I used a 90 deg bulkhead hyd fitting for the 

fuel line where it penetrates the firewall. A 

good upgrade for fire protection wherein it replaces the kit aluminum one.

PPPS,

With regard to the original issue of unequal tank 

feed - Don is probably correct in that the 

partially blocked vent is not the problem. Having 

said that I sure would not want my vent line to 

have any issues which is why I used the 90 deg fitting and SAE vent hose.

Paul-

In my IV tanks, made in 1994, the vent opening 

is so close to the top flange of the tank that 

it would be impossible to use a 90° fitting, 

because you would not be able to rotate it. 

Where did you hear about "the preferred 90 

degree fitting"?...and what makes it preferable?
