if your running out of fuel and the tank is full then a surge tank wont be the answer.

get rid of that carby pump to.

yeah, ive been running a VL turbo fuel pump with carby fuel tank forever. Works fine! Just drill a small hole in your fuel cap so it can release pressure. Otherwise it will surge and play funny buggers.

I too have been using a high pressure EFI pump on the standard carbie tank without any problems with exception to the odd surge - hole in the cap may have helped if I had have received this info a few years ago...

hole in the cap will do nothing different to actually running the Evap line into the Charcoal Canister.

although i think some people plumb the return into that for EFI conversions.

It has an EJ charcoal canister.

I'm not sure now which way the evap and return lines are connected, so I'll have to double check that. Might try ditching the ancient carby pump too.

Now it's just a matter of getting away from uni here in Kal so I can go and work on the car in Perth

I know that feeling and my car's not even that far away from me!!! Its just nothing but time...

If you have a surge tank between the EFI and the standard pump there's nothing to worry about in regards to the standard low pressure pump, if you have the standard pump and the EFI in line without a surge tank I'd def be ditching that low pressure (standard) pump!

Good thinking. My plan had the carby pump keeping the EFI pump primed, but that big EFI pump is probably trying to maintain a much higher flow rate than the little one, hence the surging.

I wanna go and play with my car!

That's how i hooked the Brumby up, but had all sorts of problems.
Deleted the carby pump and it was all good.
Give it a try.

What make/model did your efi tank come out of? Will they fit into a brumby?

L series EFI and EFI turbo vehicles.

It wouldn't be a direct bolt in job, as to wether you could get one to fit, that'd be open to speculation without looking at a standard brumby tank and the EFI L tank...

yeah efi L as mentioned above. i know little to nothing about brumbys but did they ever have any type of efi in the later years?

A bit of an update:

Removed the lift pump, so fuel is coming out of the tank through the standard filter to the HP pump, and she goes!

It took a few jump starts before working out the alternator needs an earth wire in order to charge the battery. And does the other wire (white red?) for the L series alt idiot light plug straight onto the other terminal on the EJ alt?

One odd thing i've noticed is that whenever the back end is lifted with the trolley jack centred under the diff, the right wheel stays on the ground until the left is a good 30mm or so in the air. What should one look at to fix this - bushes?

Jobs left:
-get the EJ header pipe joined up to the original exhaust
-rejig seat rails - the Lib seats are great, but too high, and my head hits the roof.
-replace pod filter with a box
-replace damaged LHF door
-finish central locking
-rego!
Should be done and on the road within a few weeks.

Nice. Good to hear she fired up ok. Was a good motor when I had it.

GOD · Post by **GOD** » Sun Nov 09, 2008 10:37 pm

On that note, roughly how many km has it done? Forgot to ask when I picked it up.

nice stuff mate- its always exciting to hear it start up for the first time

From memory I think it was around the 200 mark, assuming it is the original engine.
