2TG Fuel Pressure + Solex

[Noof]

Hi All,
Just wondering if one of those VL Commodore electric fuel pumps will have too much fuel pressure for my solex carbies? Or is it ok to get away with? Not going to be tracking the car., just street driving and nothing crazy.

If I need a regulator can someone advise which one and where to find one?
Cheers

turbosmart rising rate fuel pressure regulators are really good.... see how you go, id go get ahold of a fuel pressure gauge and test your car as is, put the pump in and test again.. then limit the fuel pressure with the regulator if the new fuel pressure is higher... but i think youll be right

[Noof]

Thanks,

Problem one is that the engine has no fuel pump and I am not sure it ever had one? I might just try the pump and see what happens! I believe that the 2TGs wanted somewhere near 3.5 PSI which I read somewhere on here.......

Can you regulate those pumps with the voltage with no ill effects?

A quick google tells me the high pressure VL pump is 40psi. That will be wayyyyyy too much. It needs to be around 4psi.

The low pressure VL pump is 3psi according to google.

Which one have you got?

[Noof]

Hmmmm Wish I knew!
Will test it when I get some fuel lines.

I am hoping that I have the low one. But I bet I have the high one!! Just murphey's law!

Is there a way to check easily.....other than pumping fuel?

Cheers

Does it have a part number on it? the 070 was the vl efi pump.

Do you know what the pump was from? The 6 cyl's were all the efi'd nissan engines so had high pressure pumps. Only the V8 (which was still carbied) would of had the low pressure pump. (I assume it had an electric pump which would be a low pressure one, but i always thought they were mechanical pumps)

As you already said you should be aiming for no higher than 3.5psi for carbs like solex's and webers. I've never tried it but I would think regulating 40 psi to around 3 psi wouldn't be the best idea. I imagine it wouldn't do much for the longevity of pump and regulator. Low pressure pumps are pretty cheap unless you go for something like a holly.

[Noof]

Hmmm I have the 40 PSI pump.... Doh!

Back to the wreckers I say! What a pain.

Should be able to swap it hopefully.
Will try to look for a carbied V8.... but dont really like my chances. What other fuel pumps provide about 3.5 PSI? Or should I get a new one?

Cheers all for the help.

[RA35GT]

I would get a new one. They can be pretty cheap.

Stay away from the facet pumps though. While they work pretty well, they are noisy as a mofo. (even when rubber mounted)

[Turdinator]

Whatever pump you get you'll still need a pressure regulator. Speco make a cheap one that you should be able to get at any parts store.

[RA35GT]

PS. If going second hand I would look at carbied japanese cars, They have sweet pumps which are fairly quiet, I had one from a mitsubishi something or rather on mine.

[RA35GT]

Some low pressure pumps are self regulating. The one from the mitsubishi i had was.

[Killa_Ta22]

I'm in the process of getting mine all running.

The car has a vl fuel pump, it was connected up to a 2tgeu.

just done a 2tg twin solex swap job, so i ordered one of those filter kings. built in filter, pressure reg and gauge. i think i may need to change to a lower pressure pump also since you guys mentioned that

[Noof]

That style of pump from the mitsy sounds good. Any idea which model?
Cheers
Nathan

[RA35GT]

Sadly no I don't know what it was from.

I will get the part number of it and try to look it up dood.

[Killa_Ta22]

Hey guys if it's any help to you's,

I just bought one of these off eBay,
its cheap and i chose the little bit higher pressure 4.5-6psi so i can set it right with my fuel reg!

Too easy

[RA35GT]

That looks identical to the facet ones.

How did you find the noise?

Mine was noisier then my engine.

[Killa_Ta22]

Not sure yet, just orderd it today, should have it tomorrow.

it shouldnt be too bad, i had a bosch 550hp pump and when it was a boiling hot day, the pump was nearly as loud as the bridgeport brappin. it was terrbile.

Then again it might be the new craze having a loud fuel pump like the big horsepowerd jap cars

[Noof]

Yeah I have a bead on the facet ones but wanted to see if I can find something a little quieter? I will probably just order a facet and box it? Maybe some egg cartons or carpet on the outside!

I might also head down to U pull it and see what I can find on the weekend too?

Cheers

Hey all,
The facet style pump works fine if you fit it at the rear of the car near the fuel tank, run the fuel line via an inline filter to the pump.
Then from the pump to the existing steel line to the engine bay,fit the pressure regulator at the end of the delivery line just under the carbys.
From the regulator connnect to the carbs and block off the return line to the tank.
I have mine running solex carbs on an 18RG and there is only a slight noise on start up as the pump builds up pressure.
The pressure regulator is set on 3 psi any lower than this and the carbys starve for fuel.
The only hassle is running a wire, via a relay,to the back of the car to the fuel pump,but for the extra effort you will be noise free.
I hope this helps.
Cheers Wheelie.
