I'm going to add a FPR to my fuel rails and had a few questions.

1) Is this set up the correct way to do it on an 02 Camaro LS1?
2) Which FPR do you recommend?
3) Do I have to have a vacuum line connected to the FPR?

Any ideas or comments would be appreciated. Thanks

Anyone running an aftermarket fuel pressure regulator that can help with this?????

That will work. If you vac reference the fpr, you will have to change the injector flow rate to a constant value. Leave the vac port open, no change needed.

Ok thanks.

Anyone know of a good regulator that I should go with?

I have an Aeromotive that reads to 100 psi.
vacuum referenced.
Connected as your diagram.

I think that's the brand I'm gonna go with. So do I just leave the vacuum port open or do I close it off with a plug?

Mine is connected to a vacuum source.

you choose to not reference it, leave the port open to atmosphere...

A second thot... the old reg may still be in the picture. Only, it now has a longer return line on it?? I think I'd take it out, all together.

OK

I'm going to take the old one out and just plug that block.

Looks good. But, if you're going to run a new return line why don't you run a new feed line and use the factory feed as the return instead? That way, you can use a larger line like an -8an for the feed.

That's an awesome idea. I am definitely going to do that. Thanks

Should I just gut the stock fuel filter on the supply line that I will be using as a return?

You could do that, or cap off the side of the T that goes to the filter and use the factory return. Just remember to remove the in tank regulator.

Ok, will do. Thanks
