It is a common swap for a lsx s10 but i wouldnt try it with forced induction, there is no way to raise fuel pressure with boost so your horsepower ceiling will be really low.

He's referring to the C5 filter that has a regulator built into it...

The Corvette regulator/filter combo maintains 58.5 psi at all throttle positions.

As was said, it should not be used with EFI because there is no way to reference the fuel pressure in accordance to boost.

Since when was boost reference mandatory... I cant speak for hp limits because I don't know but it will work just fine.
Its been years but I remember doing something like 550 whp or so through one without issues.

I bought the Wix iteration of the corvette filter/regulator and fitted it with the Russell OEM to AN fittings...



Corvette fuel filter/Regulator.

But I ended up going with the Aeromotive A1000.

What are you going to do with that Russell part that has the 2 factory looking line adapters on it? I have also wondered about using this for boosted applications. I think just for peace of mind though, I am going to just get an adjustable regulator.

That's going to be used to feed from my 255lph and 340lph fuel pumps.
If you want one, the part number is Russell 644163.

Wix is much cheaper than Gm, by about $50 thank you for posting that pic. My s10 build will be stock ls1 hp so this should work good.

However, In higher hp with boost.
What are you guy using for a fuel filter?

Thanks

Ive used the C5 filter/reg under boost and it did work, but wasnt ideal. Its supposed to be a fixed 58psi, but would actually fluctuate ~50-60. Not a big deal for most NA cars, but if your fuel system is on the edge, it can risk going lean at the wrong times. An external regulator like the aeromotive above is much safer

Mighty, you might want to rethink the 340 pump in your system. They overheat with extended use (street) and shut down. For a racecar, it wont see enough run time to matter, but be aware they support about as much as a walbro which wont shut down

Yikes! Thanks for the heads up. Better sell the 340 and get a second racetronix 255lph. I have a boost sensitive switch that was going to fire the second pump under 'x' boost.

i have the racetronix 340 in my s10 and i put tons and tons of street time on it and have never had a problem.
I have never heard of anyone having a problem with one, where have you seen people overheating them?

Google it, its NOT unique

Also, the kit is specced completely wrong. Non-submersible line, wrong style clamps. Stuff that matters

If you had great results, good for you. I had this:

To what kit are you referring ? I looked back thru the thread and didn't see a kit part number. Was it the kit you were using at the time it failed?
