buying all new fuel system, have ?ss

[taubr unit]

Time has come to redo my fuel system. Doin a 255 pump, filter 30lb injectors but what does everyone do about the regulator? My stocker has 100k on it so i want to change it out. I want all new parts on my fuel system. How many people use aftermarket/adj. regulators vs. a new stocker?

And when it comes down to tuning, whats the difference between using the reg. to up the fuel pressure as opposed to doing it with a tune?

You should be fine with another stock one. Get a racetronix system, that will give you room to grow (600hp).

I've got a Brand New Holley stock replacement... It has been installed on a set of rails but never any fuel through it... Nice shiny aluminum. Allows adjustability if you ever need it.
As far as tuning, you wont be tuning with the requlator... But it's nice to have the adjustability if you ever find yourself too high in the injector duty cycle and need to raise pressure to get your pulsewidths down.

PM me if you want this regulator... Ive got almost nothing into it, and its been around for a long time. Sittin in it's box ready to go.

i went with a aeromotive FPR. nice fit and looks good

HIJACK: I think I may have some higher rpm issues with my stock fuel system (probably injectors?). I'm thinking of upgrading my injectors to 30's or at least something better than the stock 24's. The car is a '96 w/ 115k miles, and the fuel system is all stock. I'm shooting for around 350~360hp (eventually after a H/C swap) and maybe use some N2O down the road to get to 400~420hp. I have the gut feeling that it'd be good to revamp the whole system but, my questions are:

1) What are some recommendations for my intentions?

2) Would anyone recommend AGAINST doing this piece by piece vs. all at once? If not, what would be the best order? I would like to do it all at once but, depends on my patience level in saving up the funds.

Also, I'm not necessarily looking for the cheapest stuff out there. I would prefer to spend more money when there's a reasonable benifit or feature involved. My main focus is to have reliability and consistancy. Thanks.

First off, what brings you to the assumption that it's the injectors? By my experience, the stock 24's are plenty for the power level you are speaking of. Unless you plan on a dry shot to get you to the higher levels.

You should put a fuel pressure gauge on it so that you can watch pressure through a full WOT pull. If it drops, you need more head (pump), if it does not then the next step is to get ACTUAL A/F readings and if you can injector duty cycle data. This is the only way I know of to determine a lack of injector.

Either way, an adjustable fuel pressure regulator should be enough to get more flow out of the injectors. And if you plan N20 in the future, a fuel pump upgrade is gonna be mandatory. But even at the 400ish HP level a simple intank Walbro 255 would be plenty.

Aeromotive adjustable regulator, and make sure you have a gauge at the rail! Been there done that, trust me!

It's not that I think I have a problem with the stock size of my injectors, but rather, I'm currently wondering if mine may be acting up. I've had a weird A/F issue thats very apparent on the dyno above 4500 rpm. Old motor and new motor do it. I have changed quite a few parts now that would be assumed culprits but, never thought about checking my fuel system (dee-dee-dee). I saw some of those youtube videos of bad injectors and it just got me thinking about it. I'm going to get mine checked out soon but, am wondering if its worth going to a little larger injector if I choose to get new ones. Even if I stay the same size, I'm sure there's got to be better technology put into todays injectors over what came on my car in 1996... yes/no???

Now for my dumb question, anybody have links to write ups or pictures of how you installed your fuel pressure gauges on the rails? Is that something you guys are leaving on there permanently or just temporary to check and make adjustments?

I've got a lack of knowledge on fuel system info and mod's even though I've been into this car for about 7-8 years. So, yeah, gotta start somewhere.
