What's the easiest/most cost efficient way to increase fuel pressure??

[kna4977]

First off, I'm looking at purchasing a street chip from Eric at TurboTweak, but he told me that I will need to increase fuel pressure to get the most out of this chip without running into problems such as running lean/knocking. What's the easiest and cheapest way to do this? Do I just need to purchase an adjustable fuel pressure regulator? If so, where is the best place to get one? How capable and bullet proof is the stock fuel pump? Do I need to change out the stock injectors or can they handle all of this? What are their capabilities? Also, do I need to add another pump? If so, how hard is this to do, and can it be done outside of the tank without altering anything that appears stock? What is a hot wire fuel pump? thanks

you need a adjustable fuel pressure regulator,a hot wire kit is basically a relay with heavier guage wire comming straight from bat or alternator giving full voltage to youre fuel pump this kit uses youre original wirring to power new relay.i think every one is using the walbro in tank fuel pump i think they claim is enough to support 600 hp....iam no expert but youre in the right place this is the best site for info hope this helps

Thanks for the info. If I just add the adjustable fuel regulator, will that be of any benefit?

I just saw a new 340 and hot wire kit, still in the wrapper for $100 on turbobuick.com

What all is involved with the installation of the 340 and hot wire kit? Is the Kenne Bell Boost-A-Pump of any value?

Boost-A-Pump is a patch for something that was inadequate at the factory. Why try to cobble your weak factory 20+ year old pump along? Kenne Bell dropped all their Buick parts, anyway. They deal with the Ford crowd, now.

Just adding the regulator will not help fuel delivery. The volume isn't there to begin with. You need both pressure and volume improvements.

I suggest dropping the tank and doing it right to begin with. With the 'hot wire' added, you'll then have enough flow for 600 HP, as noted. Do it once, and do it right.

I am all about doing it right the first time............what do you specifically suggest a 340 and hot wire????

[Keller]

Amen.

That, plus an Accufab or generic adjustable regulator and you'll be set. :tup:

What is a hot wire? Which pump and regulator does he have?

[kna4977]

Is it possible to get in the low 13s mid to high 12s for $500 or less???

[kna4977]

Is the Walbro pump any good??? If so, how difficult is it to install? How difficult is it to install any fuel pump? Do they make external ones that are any good? If not, how much of a PITA is it to install the internal pump? Do I have to modify anything from stock or would it be a direct bolt-in? thankx

The pump involves dropping the tank .. it's not really that hard, but requires some effort. Installation article is in the Fuel System section of the Technical Articles on the site, I believe.

Low 13s/high 12s can be done for around $500 (not counting sticky tires). Pump, regulator, chip, CAI, exhaust dump.
