Carb Fitting
 

trying to mount a dual feed fuel line on a 4150 Holley ... where the fittings screw in to the carb. you cannot get enough bite with a wrench to tightenen the fitting... It is a 1" nut ... only thing I can see using would be a deep well thin wall socket ... the front fitting is almost 3" long. The rear is short. You can get it snug ..... But there is too great a chance of disaster with just a snug fitting ....

k-d tools makes a special thin wall wrench. it looks like a box wrench with a small section missing, similiar to an oxygen sensor wrench. it works very well.
