Surge tank, commodore V6 conversion.

make sure you keep the dampener as close to the outlet of the pump.
My mate has got a 74 lancer with 2.6 efi turbo he kept burning out pumps because he wasnt using one.

The dampner is on the side of the plenum, guessingit can be moved as an inline item looking at the size of it?

Just remember keep the pump mounted as low as possible and electric fuel pumps push a whole lot better than they suck so keep it close to the fuel tank.

When you have a LP pump feeding a tank, feeding a HP pump, are the 2 pumps are wired up on the same circuit?

I have a Marks kit here unused. Will do it for $200. It includes the lift pump and happy to post.

The reason I have it is I didnt use it when I did my conversion. Mounted a VL pump mounted to the chassis. Did burn one pump out, but it was s/h when doing the conversion. As RUFF said if they get dry they burn themselves out very quickly.

Generally I leave th low pressure pump on as standard if it had a low pressure pump, or hook it to ignition on, the high pressure pump is controlled by the ECU

Here's a pic of how i've set up my surge tank and pumps. Tank is about 1.5lt made from 1.6mm stainless, the lift pump is a pierburg (upper) and a high press bosch main supply (lower).[/img]

I used the aluminium aircon receiver that I got from the commodore donor vehicle. I made a top for it out of 10mm ally plate and drilled and tapped it for the fuel fittings and got it welded on. I ran a dropper tube of copper silver soldered into the EFI pump pick up so it was about 35mm from the bottom and all the other lines were 1/4 inch and set up as dai-hard suggested. I mounted the surge tank up under the tray and the EFI pump down on the chassis so it was gravity fed. Worked well and cost very little.

That is a very neat looking idea aswell, I would have the same if not more room under my tray. It is good to see one mounted as I was having nightmares thinking about where I could put one in the upright position

Was the box custom made, does it have a cover, how well sealed is it and how does it clip on?

[dai-hard]

I like the box idea too.
gives it some protection from stones/mud and crap.
Ill start making mine tomorrow at work.
I also run a filter on the low pressure pump will put it in there to but keep my hi pressure pump in the engine bay.

Gday High n mighty, I'm a sheety so it was not too difficult to knock this box up. It does have a lid and is attached using some sash clamps that we use at work. It's not 100% sealed around the lid but facing it towards the rear seems to stop just about all the shite getting in. The lid does however fit into a slot at the front edge of the box sort of like how a butter containers lid fits and this also stops crap gettting in. I used threaded glands to seal around the fuel lines and work a treat. A fuel filter is used before the lift pump and another in the engine bay before the injector rail.

[high n mighty]

Well now I have a lift pump, VL external pump, pump bracket and surge tank on their way. All brand new

If I give you the dimensions of the surge tank when it arrives do you think you could knock me up a similar box Luxemburger

[pigletracing]

it all looks like alot of work for not much extra advantage's
I run a V6 in a comp truck,with 3/8 lines, 1 x VL pump,no surge tank,
& no problems,,I have had her on extreme angles:ie long winch stages up
vertical inclines,I think the trick is on the fule pickup line in the tank
I added some flexable rubber fule line (this allows your pickup to follow the fule around the inside of the tank,no matter what the angle) I then addae the same legnth to the return line,then cliped it to the pickup (this way any fule being returned is virtualy fed to the pickup,good luck PIGLET

It might be well worth putting the money from this project into running straight LPG, then you wont need any petrol tank or the BCM signal to the ECU as the injectors wont be required, the way petrol prices are going!

The engine will run on LPG without the Anti Theft signal and you don't need to start the V6 on petrol. I know, I've been running mine like that for 12 years.

If your worried about running out of gas with 1 tank, go for 2
