HSR Fuel lines

I am about to do a HSR swap and I know you have to do changes to the plumbing and on stealthram.com, they have a kit for this, but the link doesn't work anymore, so is there another place that sells the lines or do I need to pick and match parts from other resources? Thanks.

email stealthram.com and tell them the link dont work and ask for the kit info. I cut my stock lines and replaced with new ones when I had HSR.

I used part of the stock TPI hard line that attached to the rubber line and had a shop weld a -6an end on it and just ran braided lines to the HSR

So I can just buy some braided fuel lines and get a -6 AN part welded onto the stock line? Seems a little too good to be true. Thanks for the help.

Yep.
The shop that did it charged me a total of $20, parts and labor.
They do make adaptor fittings, but I couldn't find any and Jegs didn't have any instock. The adaptors are basically the same as what I had made up.

Are there any other online stores that would sell these adapters? Also, since we are on the subject, what problems did you encounter during the installation and is there anything I should look out for? Thanks.

It is really easy. Just cut the connectors off of the body's hard lines and flare on some new connectors. Use braided 6AN line to go to the fuel rails and then use the supplied connectors that came with the fuel rail kit.

Most people will install the adjustable regulator backwards so that the adjustment and vacuum line are facing away from the distributor, makes it easier to adjust and put the vacuum line on.

Yep, no welding needed...

Thanks for all the help guys. I'm pretty new to the plumbing of the car, so I'm not sure what these adapters look like or where to buy these and the braided lines. Pics would be great. Thanks again.

an Industrial Hydraulic Line shop should have all the fittings, Hoses and adaptors.

Was this swap pretty straight forward or did you run into some problems? I'm going to be using my stock throttle body and I've heard of some issues with that. Any heads up would be greatly appreciated.

Re: HSR Fuel lines
