I am replacing the fuel pump on the wagon this weekend. It is a pump without a return line. I have been thinking of putting in a fuel pressure regulator. Is that a good idea without the return line? The reason for the fuel pressure regulator is to make sure I am not too high. The car runs good and smooth, fires right up, timed correctly, etc. but I still get alot of excess fuel smell even after stepping the Edelbrock carb 6% leaner. Any thoughts?

I did double-check my Malibu and it has the return line. That makes it much easier to put in the TPI set-up. Woo Hoo!!

Is this exhaust smell?

Yes.

It could be a fuel pressure/carb problem, however "exhaust smell" can come from too much advance at idle as well.

If you are using a manifold source for the distributer, try switching to the ported source, reset the idle mixture and speed, and see if it goes away. If not, look to the carb and fuel delivery.

And the answer to your question is yes, you can use a "deadhead" regulator.

Greybeard,
Thanks for the info. I am using the carb port for my distributor vacuum. I have reset the idle mixture and speed. This all previous to putting on a new fuel pump. I just got it on today and will work on tuning it again.
