I am looking for input on 1998 cars only. These cars had a metal fuel tank and I believe are setup differently than the 1999-2002 cars.

Now just to be clear I know that ALL LS1 from 98-02 had the fuel pressure regulator IN THE TANK. Please do not come in here trying to tell me it's on the fuel rail, thats a pulsator not a regulator. Again, the regulator is IN THE TANK!!

Now my question, is the fuel pressure regulator built in to the fuel pump itself? Or is it a seperate assembly in the tank?

I am replacing my fuel pump, but want to replace the fuel pressure regulator while I am in there.

This is the fuel pump I am thinking of buying

If you buy a Delphi (OE supplier) fuel pump module for a '98, you get the entire assembly, which includes the FPR (it's part of the module but not contained within the actual pump itself). I don't think any of the aftermarket upgrade pumps, including your link above, come as a complete assembly like that.

Thanks for the input.. i wouldn't mind ordering the fpr seperately if I order the fuel pump from my link (WS6store) ... question is what fpr do I order and from where?

Seems like alot of guys try to order from GMpartsdirect and they end up with adum pulsator -__-

I don't know if the FPR is orderable separately, at least not from GM. Delphi was the OE assembly line supplier for these pumps, and what you get if you order a replacement module from GM (or Delphi direct) includes the FPR. Often times, when they include an item like this as part of a greater assembly they don't also offer it as an independent part.

You could try some aftermarket sources though. I've never tried to get one separately myself, but I doubt GM will offer this.

I'm gonna go with the Delphi module w/ fpr included. Happen to have a link to where to buy it? I tried searching but didn't come up with anything.

Thanks again for all your help

The GM part number used to be 19179530, but since Delphi is now independent of GM, I'm not sure if GM continues to use the original OE module as their parts counter replacement for these 17 year old cars. There are cheaper brands/suppliers as well (such as Airtex), but their quality is not as great.

Having said that, if you want to be sure to get the original assembly line module, you can do so directly from any retailer that sells the Delphi brand. The Delphi part number is HP10038 for a '98, and that's the complete module.

I had to buy a new fuel pump assembly a few years ago from O'ReilleyS for $238. There were/are no aftermarket replacement pumps with fuel lever

In the 99+ cars they are like $100 for the assembly

$238 sounds too cheap for a Delphi complete assembly, did you go with an Airtex, Carter or some other brand?

The Delphi pump (HP10038) included the fuel level float, wiring harness, and everything else (complete assembly) as recently as the summer of 2012. A quick online image search seems to show that this assembly still comes complete but retails for more like $300-400 depending on the source.

Further investigation shows that O'Reilly doesn't recognize this Delphi part number, so that might explain why you couldn't find this complete assembly there.

At what point (power/mod wise) does one actually need the higher output (I'm talking about the Granatelli/Walbro/etc. level pumps NOT the 50 lbs. of boost, 900+ WHP level, Aeromotive Phantoms, etc.), NOT complete assembly, aftermarket pumps everyone on here swears you should put on even a MILD bolt-on car??

In other words, what are the Delphi complete assemblies good for as far as max power/mod levels go, since this is what was put in my tank 2 years ago??

Many people tend to campaign for the higher output aftermarket pumps as a matter of principle I think, arguing that it's a good preparation for future growth....though not everyone will ever pursue such growth. I've never seen the need for one at any sort of bolt-on level, and in my experience even mild heads/cam setups will be fine with the OE Delphi (assuming it's not worn out). As you mentioned, forced induction/N2O or very high fuel demand (meaning big cube/high rpm max effort) NA setups are obviously a different story, but personally, for a stockish/mild car, I'd rather get a completely new OE Delphi assembly.

Do you not recommend one of these? Do people have bad experiences with the aftermarket assemblies?

IMO, Carter and Airtex are a step below the OE-level Delphi quality-wise. They are also cheaper so that might be a motivator for some, but I'd rather have the Delphi.

Do you have any experience with those or have you heard of people with bad experiences?

I've needed new pumps in several different applications. My research showed much higher occurrence of premature failure with the cheaper brands, so I never bothered to buy them. I've been happy with the Delphi products though.

Ok I may have come up with a plan of action.. Use one of the Racetronix fuel pumps ($149) and buy one of these AC Delco OEM regulators for a '98 LS1 ($64) ! Just to be sure it really is the right regulator for a '98 .. I searched the part number, and Rockauto.com lists it as the right one for a '98 LS1 as well.
I hope it is. Thoughts?
