i just got done plumbing my fuel system on my 82 c10 and i used this russell adapter Russell Performance 640850 - Russell Fuel Rail Fitting Adapters - Overview - SummitRacing.com i ran new fuel lines and AN fittings it was not to bad. i would not reccomend to go cheap on the fuel system. for the hard line you cut you can use this Summit Racing SUM-2200075 - Summit Racing® AN to Tube Adapter Fittings - Overview - SummitRacing.com i had to use one and it seems to work well.
