Hose clamp pressure limits.
What's a good rule of thumb for a pressure limit of a hose clamped onto a non-barbed nipple, like a cut hard fuel line? I'm using a cut hard metal fuel line as an example, with some rubber hose slid over it, clamped with a very standard hose clamp. Thanks for the help.

I've used this over the years and never had a problem. Have also read several professional articles suggesting this procedure.

The reason I ask, is because when I do this LT1 intake swap...I will be adding an inline fuel pump back by the tank. It'll be a TPI style pump, with just over 40 PSI of fuel pressure, regulated at the intake. I was wondering how to tap the fuel pump in the line, seeing as how the electric I have now is just held in with hose clamps. But, it's a 5-7 PSI pump.

Several companies including Russell make a compression fitting which will tighten over a round hard line and adapt it to AN fittings. It is a convenient way to transition without doing a 37 degree AN flare.
