A 45* fitting will do wonders... but if you didnt use that throttle cable set up it would fit.. I use that same one EDIT My bowl entries are on the pass side of the carb.. you might want to swap the bowls end for end to get them on the pass side...... never mind... I see thats for a regulator or a solenoid
A 45* will work, but if the designer took five minutes to test fit the bracket it could have been made to work with any fitting. Instead I have another $100 worth of junk on the shelf on my shop.
It would be great if everything worked with every combination of parts you may want to use, but it doesn't always work like that. The bracket has extra clearance to also work with 50cc pumps. If the line fit, but it wouldn't clear the pump arm, guys wouldn't like that either........LOL!!
