Fuel pressure regulator+fuel pump?

HiFlow5 0 · 03-14-2002, 07:51 PM

I'm not sure but I think my car is running too rich. At an idle it smells like gas pretty bad. I'm thinking of getting a bigger fuel pump, maybe 155LPH to replace the stocker. I'm also thinking of getting and adjustable fuel pressure regulator. would I benefit from these additions, and what would be a good place to set the fuel pressure at for my mods?

I'd say you should upgrade the fuel pump to a 155 at least or a 190 if you are going to do more mods later, like alum. heads and such. I'd highly recomend the Kirban adjustable fpr, it's a sharp looking unit, it's rebuildable and it's also only $70 at jdsperformance. I set mine at 34psi with the vaccuum line removed and my finger over the vaccuum tube and i was a little lean, I have it at 39psi now. But I'm running Edelbrock heads a TFS stage 1 cam and ported Cobra intake so I'm probably gonna need more fuel than you. Factory setting is 35psi i think but the only real way to know where it should be is to get your air/fuel ratio monitored like it is on a dyno.
I had the same problem on my baseline dyno before the head, cam and intake swap, the exhaust was so rich it made my eyes water. Don't have that problem now.

I've heard an adjustable fpr can be good for up to 10 hp. One of the best simple bolt ons I've done

That's more of a regulator problem than the fuel pump, IMO. The stock fuel pump is adequate for a stock setup, but i'd upgrade with ported heads a cam and intake. And an adj. fpr I've heard recomended even on bone stock motors. Like I said one of the best bolt ons I've done. But that's just my opinion.

That did sound like weird advice though didn't it.
