89lsiroc

Doing an ls1 swap in my 89 iroc, do I use my stock fuel line or do I have to change them? If I have to change them is there a kit I can buy? Thanks.

You will need several adapters and either run a 4th gen tank or get an in line fuel pressure regulator. What kind of set up are you going to run? Here is a link to the normal fittings people use.

That would go on the rail to connect to a female -6an, as well as the two connectors on the gas tank if you want to run the 4th gen tank/pump.

I think Hawks has a kit for a pressure regulator if your running tor 3rd gen tank, but just regular fittings and stuff I don't think there any kind of kit. I flared my hard lines and put -6an fittings on them.

You would still need one of those adapters for the rail and a adapter for the stock fuel fitting to a -6an to run that kit.

I'm using the stock third gen tank, I have the inline filter with the regulator, mostly what I'm wondering is what do I need to connect to the fuel rail on the ls1

This is what goes on the rail.

Then probably a -6an flex hose and something to connect it to the hard line up front.

If your running the vette filter you will need two more of those, something to get the feed to the stock feed line and also an adapter to connect to the hard lines on the car already. Or you could probably run a flex line all the way up front from the filter if you prefer.

That's the kit I bought, now I just need to know what I need to connect the fuel line to the fuel rail on the ls1

That kit will get you -6an male to connect back to your stock tank and a quick connect going to the front rail. None of this connects to the stock lines though. Are you planning on putting the filter in the stock location or up front? I ask because your normal return line goes all the way up to the throttle body.

I used nylon lines & fittings from the stock TPI lines to the vette reg/filter.
