Help getting these fuel fittings apart

[sed6]

My fuel hose from the PT to the filter is cracked and needs replaced. I couldn't get it off the filter so I took the whole thing off and brought it home to work on my bench. I've put about 150lbs of torque on the fuel line fitting but it won't come loose from the 90 degree elbow. I've soaked it for an hour in PB Blaster and still no luck. I'm concerned I might break elbow if I apply too much torque. Should I try a torch to heat the elbow? Other ideas?

And while I'm at it, suggestions on getting the canister off the head? Strap wrench? Other?

Thanks!

As for the canister, I've always just used a 3/4" box wrench. Never had a problem.

The canister is held on by a long metal bolt through the top lid in the middle. Sometimes a 50/50 mix of acetone and dexron does wonders but it might need to soak more than an hour....

Just take it to the hydraulic shop with you and ask them to remove it they should have line wrenches that size and not damage anything.

Got it! My friend recommended CRC freeze off. That and a breaker bar got it off. Going to take the hose to a local shop in he AM and have a new one made. You can see the cracks in this one if you look closely.
