Mass air flow sensor

(1991 Isuzu Pickup)
in Tulsa, OK on May 06, 2011
where is the mass air flow sensor located on a 1991 Isuzu 2.3L pickup engine? Picture if possible. New fuel pump and filter. New head and intake gaskets. Starts and runs for about a minute then dies and won't restart for 1/2 hour or so.

Left - front of engine compartment. It's between the air filter housing and intake manifold, in the intake hose. Unfortunately we can't post a picture here.

I really appreciate your response! Thanks, Bro. But my air filter housing doesn't have a hose to the intake man. It's carburated so maybe that makes the difference. Even the manuals don't show a pic of the M.A.F. sensor that I can find. but the parts people have a replacement part for that year but no idea where it goes. I've read online that this part will cause my prob if defective... but no one knows where it is. And yes I've had a pro mechanic look at it and he is the one that told me to replace the fuel pump. No easy task on that motor.

Carburated engines don't use a MAF sensor, it's for EFI engines. The Stormberg controlled air/fuel ratio carburetor incorporates a duty solenoid, to carefully maintain the air/fuel ratio in accordance with the ECM control.
Is this the part you are looking for? The DS Valve is part of the carburetor assembly, it replaceable however. I believe this is the only electrical part in it, beside the electrical choke.
If this is the part that you are looking for, let me know. I probably can give you more info.
