For all those that have the HSR installed, what things did you find you needed to complete the job. I know this has been asked but I want answers from everyone on everything they needed, The GMHTP HSR build up shows quite a few things but has anyone used more or less or different stuff? also, will i need to buy any O rings?

 

the only PITA i ran into what the fuel line routing....i have the engine out of the car now, so its giving me some down time to play around with new lines. before i just ran temp rubber lines

 

the fuel line routing is a concrn for me. Does the HSR have a fuel line setup directions? Is there more then 1 way to set up the rails and fuel lines? does the rails get fuel from the front or back?

 

Check the sticky at the top. I have the exact same questions as you. It appears the fuel lines connect in the rear for the HSR but I was told I could keep the stock lines intact and buy new fittings. I guess this would require running fuel lines from the new rear location to connect with the existing stock/front location.
Since it's not as clean I guess that's why many are cutting the stock lines at an ealier point and routing them sraight to the back.

 

I realy dont want to cut my fuel lines in case I decide to switch it out again in th future but I guess if it looks better I have no choice. I just want to be 100% sure that cutting the lines wont make any leaks down the road

 

It's not a bad idea to get new o-rings for the feed and return line - especially if the stock lines have been removed / loosened and tightened couple times there. I tried to get away with the old ones, but had a mild gas smell under the hood until I replaced them.

 

I addressed some of your questions in this thread in case you have not read it.
