Trim tab tubing options?

[Timangas]

My trim tab lines are leaking at the fittings and I am trying to figure out the most cost effective way of fixing them. I looked up the Bennett’s lines but am not trying to drop the $40 on them as I am saving up to get an edge rock carb. Will any other kind of tubing work for the trim tabs? I bought some 1/4 inch plastic vacuume lines from oriellys but the compression fittings don’t seem to fit on. Is there a special tool to crimp fittings? I’m lost. Thanks in advance

If they have not change the hose design, they use nylon rigid (hydraulic) tubing with ferrule type connecter

Would not be surprised if it’s not metric tubing. Pretty common stuff in the industry. Measure the od of the tubing

getting the correct bennett lines is the same price as buying stuff that wont work.

you literally are complaining about $40 and the difference by the time you are done will be less than $5 once you get the tubing, nuts and ferrules

however because you bought a bunch of stuff that wont work....... your repair will actually cost you more now as you go back and buy the right stuff.

no way a vacuum line from oreilys is going to hold the hydraulic pressure generated by the bennett pump

remember, that little pump can generate some serious pressure

I went through this a few years ago.
I wasn't trying to save money but I needed hose asap and the Bennett hose was going to take awhile to get.
I used Parker NBR-4-050 hose. It has a burst pressure of 2500 psi.
My notes show I might have been able to use NBR-4-035 with a burst pressure of 1700 psi but I'm not sure about that.
I went for the higher rating and wasn't concerned that the tabs might move slower.
