In order to help our customers out, and offer the best options we can, i took home some brand new 99-02 fbody fuel pump modules last night. We now have 3 x 255lph kits done and 1 340 kit done and 1 495lph kit nearing completion.

Unlike quite a few kits out there, every one of these are different and exclusive to ws6store in that they are
Brand new
Drop in
Premodified
New fuel level sender and arm
No holes drilled
Use factory style sealed bucket for constant fuel supply
Tested to guarantee proper operation
AND THE BIGGEST OPTION
ALL HAVE VENTURI FUEL PUMPS
255, 340 AND 495

This means your pump module will always have a constant supply of fuel. There are other more expensive options on the market that just hang some generic pumps into the tank and really hope for the best, and everyone knows thats definitely not the best way to do things. Or we hear customer horror stories about how they drilled holes or cut the whole bottom of the module out and let it sit near the bottom of the tank supposedly. This completely defeats the idea behind both the bucket and the venturi system. So why not keep both and get a brand new module in the process?

We will be offering the 340 and 495 kits without internal fuel pressure regulators only. So you will need to find a solution there, either our C5 kit or an external adjustable fuel pressure regulator. For the 495 kit we HIGHLY recommend the racetronix fuel line kit complete with fuel pressure regulator. The stock lines really cannot handle the fuel capacity this pump can produce.

Speaking of the 495 unit, lets talk about it. It makes 495lph at 43.5 psi and 406lph at 60psi. The capability there is pretty incredible AND it only requires 18amps instead of the normal power hungry 450lph pumps out there needing 22-27 amps. So less current draw and way less heat buildup!

Pricing
For the 255 kit they are normally $420 shipped WITH new hotwire harness (subtract $60 if you already have the new flat style connector hotwire harness)
340 kits are $440 shipped again WITH Hotwire harness. Subtract $60 without.
Price on 495 kit will be posted tomorrow.

We had 3 255 kits available at the beginning of this post, and now we only have 2 left, so they are going SUPER fast.

They do come with new tank seal and a new flat body side harness pigtail in case you are just using the factory 255 as an upgrade but using factory harness. 340 and 495 kits definitely need the hotwire harness. 340 and 495 kits will have return fuel line already installed from the c5 kit also.

Ill have a somewhat detailed write up on install soon BUT there are literally 10+ styles of modules so they will be generic which does suck, but at least itll help!

Now some pics!!

thats what I did for mine.. bought a OEM Delphi fuel pump module and swapped in an Aeromotive 340 and didnt have to hack up the bucket or anything and its worked like a charm ever since I installed it.

 

Hey there,

I was just about to buy a Dual 255 (510lph) racetronix fuel pump. ($220) ? Should I wait for this pump instead? Will there be a "pump only" option like for the dual 255's? So basically, much cheaper than $4xx?

Or will this be sold exclusively with the whole kit?

Thanks,
Andy

 

That really depends on your power goals and setup. Let me know what build you are looking at i can help.

 

800whp via forced induction. (Procharger) on 91.

 

If youre going that high then stock lines arent going to feed that. So youll need the fuel line kit also which comes with a new regulator.
The 495 would be a good option there then.
We will likely have a drop in kit soon after some testing. Will keep everyone updated

 

Interested in pricing for the 495 pump.

Would it be possible to buy this without the hotwire kit since I already have that when I purchased your 340 pump? If so, how much?

Also, could I run this on stock fuel lines or is it mandatory to upgrade with the 495? I already have your C5 fuel filter and regulator upgrade kit installed.

 

Badass for guys that don't want to do this themselves and that's a killer price too considering what you get.

 

Great work there!

I'm definitely interested in the 340 perhaps the 495 drop in for my current 99 Camaro LS project. This is a V6 car that's getting a LS370 and I will needing to modify the entire fuel system because I think the fuel lines on the V6 car are not the same as the V8 cars. What other products do you offer?

 

Fuel line upgrade 100% necessary.

340 is fine for most applications when properly plumbed
Some 3800s are returnless but either way very little issue

 

98 pumps now available

How much rwhp can 3 of the 255's handle on E85?

 

I would not recommend 3 pumps. Really ever. You run into so many issues there. A dual 340 will ideally handle about 1200 when done properly. A dual hellcat about 1350 or so. Above that youll need a much different system and pump style.

There is a very easy calculation for all of that.
Find the fuel curve of your pump at 13.5v and check the voltage/amperage curve also. Make sure your charging system can handle that load without issue.

For the fuel curve, check your nominal fuel pressure and then check the flow at that pressure. convert that into lbs of gasoline per hour. Divide by 8.
Then use that number to calculate the fuel injector size you will need using one of the many calculators from DW, FIC, Witchhunter etc.
That will get you in the ballpark.

Also remember, this is ideally targeting an afr in the mid to high 11s for boost if using .6 or .65 bsfc normally from what ive seen. Ethanol fuels are usually in the .7 range. Some use .77 but that is due to them using an ethanol afr of 9.xx to 10.0 which is definitely not the way to tune ethanol equipped engines. Most of the more reputable tuners and fast lsx combos are targeting GAS afr meaning again mid to high 11s with 0 issue. Even on higher compression setups.

Keeping the fuel system as simple as possible is the best way to do it. Meaning the least amount of pumps, switches, wiring, etc. And the least amount of electrical load.

 

Heh I misread the initial post and saw “We had 3 255 kits available” and misread the “3” as being 3 pumps rather than 3 complete kits lol...

 

No problem!

 

Is there a simple "plug & play" replacement fuel line (and maybe rail) "kit" for us hardheads that already have (Hotwired) dual 340's, 1000cc injectors, and insisted on keeping the stock lines, and the hacked to death factory bucket? lol.

I'm "probably" making 600-ish or so to the tires, in a single 78/75 turbo setup, on straight E85, but already logging near 80%+ duty cycle.

 

You dont need dual pumps for 600 or 700.

But the best kit is here. Comes with everything needed and will work up to 1khp.
Racetronix complete fuel line kit

And our 340 single can handle that without issue.
Above that a single hellcat can do about 900 with that line kit or 750ish on stock lines BUT MAKE SURE you have a good alternator/charging system.
Even with a hotwire kit, if you aren't putting out 13.5v from the alternator at least and a good amt of current, bigger pumps wont make a difference. Our modules keep everything intact and so far are the best option for feeding the pump and keeping it cool and fed.

 

This kits with the a 340 pumps still available? Need some help figuring out what I need for my combo to run e85?
