Pressure to tighten down fuel hose clamps

[argniest]

Some of my near term projects will be to reinstall my gas tank, it is being cleaned boiled, acid washed, sealed, etc. Very soon now I will have it back. And then I have a new bosch fuel pump to install, new inline fuel screen between tank and pump (because the one inside the gas tank got eaten up by the acid I am sure), install new fuel filter, and new injectors too.

I also purchased new replacement fuel and fuel injectioon class hoses for the rear of car and engine compartment. I also plan on carefully taking off the fuel rail and soaking it with carb cleaner before sticking in new injectors.

My gas tank was totally polluted with a LOT of rust. Im talking about 1/2 deep of it. And there was some other rusty areas like the top of it. Although it was not a terrible amount that was seen on the top of the tank with the snake camera.

But it was still bad enough though to require the acid wash.

And in the first place, it took like 30 minutes to rinse all that rust out, once I got the tank off the car and could spray it out with pressurized water sprayer. That was step 1 before I dropped it off to be restored.

Soooooo to the point of all this: something I do not understand is how do I know how hard to tighten down all the fuel hose clamps. I will just replace them one by one.

I would rather not guess at this, but use the correct pressure. There must be a tool for this right? I dont want to screw around with leaking fuel, like ever! So I would rather do it once and do it right, since I will have new hoses. And I dont want to tighten too much either and ruin the hoses. They dont grow on trees and have taken me a while to secure.

Go to a plumbing supply house, they sell the band clamp torque wrenches.

I just tighten until the clamp presses into the rubber by the thickness of the band. I don't know if that's a good guideline, but I've never had any problems.

And for those who like numbers:

Tightening torque of fuel hose clamps:

... 0.10 to 0.15 kg-m

(0.72 to 1.1 ft-lb)

Yeah, but that's with a Datsun-styled clamp, not with a worm-gear type band clamp.
