GSL-SE fuel pump flow?

[PercentSevenC]

Anyone know what the GSL-SE fuel pump's flow rating is? To cut costs I was thinking of using one on my blow-through project for the time being.

[Jeff20B]

Don't they flow at least as much as a walbro 255lph? C'mon guys. Anyone know?

[WE3RX7]

I dont think they'd match the 255lph. I'd imagine they are closer to the S4 NA 13B pump which is less than 255 - I used to have a chart somewhere...

Either way, it wont do for much more than 6psi I'd imagine...

gsl-se pump will work fine for a blow through turbo they put out like a max of 40psi

[PercentSevenC]

It's not the pressure I'm concerned about; I know that will be plenty. I'm concerned about how much fuel it will flow at lower pressures, like around 15 PSI. I think it needs to be like 30-35 GPH at that pressure.

[Jeff20B]

Does anyone know? You might want to ask on the other forum. It's important because I found a GSL-SE pump for you. I'm working out price right now.

Well before i went turbo on my 12a i was told that that pump would be great for blow through. i couldn't find one so i got a msd 2225 works great.

[Jeff20B]

Thanks for the info.

[PercentSevenC]

Yeah, I was thinking about using a Summit-rebranded MSD 2225 as well. I think the GSL-SE pump should probably be enough for now, too, so it'll come down to what I can find when the time comes.

[BadAzz84]

Should work either way guess you could use a wolboro.

[Jeff20B]

You could use the GSL-SE pump while you're running 5 psi. You're looking for cheap solutions and this is it. :)

After research, I FINALLY found the answer to the original question:

Specifications:
Design: Intank
Flow: 160LPH
Minimum Voltage: 12V
Max Operating Pressure: 95 PSI
Part Number: SPPG-392

It is the same part for:

1986-1989 Acura Integra
1990-1992 Daihatsu Rocky
1984-1985 Mazda RX-7

I hope this helps you !

The GSL-SE pump is external. Your list states Intank.

Go to your local Dodge dealer and have a look at the fuel pump that they use for the viper. It’s a Bosche pump that is identical to the HKS upgrade pump. One of my guys picked one up and put it in his car and the pump only cost about $130. Check it out.

I ended up picking up an MSD pump for like $40. But, good to know. Is it an external pump?

yea....something doesnt add up

Mazda specifications for fuel pump and stock injectors.
Outlet pressure 350~500 kPa (49.8~71.1lb/in2)
Pressure reg no vac at control solinoid 260kPa - 36.97psi
vac at 200kPa - 28.44psi
injector volume 173+/-24cc/15sec.
Don't know if that might help someone figure it out.

Mazda doesn't give a fuel pump volume spec for the EFI cars as it does for carb models.

I never checked what an unrestricted pump puts out on the se, Do know that it really makes one hell of a mess if you do forget to hook it back up.

Since Mazda no longer sells the pump for the GSLSE the walpro seems to work alright on a flow ported motor and intake which passes IM240. Still working on my se although it does make some noise once and a while.
