Hay all

I now magnas seem to have a problem with cutting out on low fuel. So i was wondering by upgrading my fuel pump to a better quility pump would improve this cutting out. But do everything else as the stock pump would do. Wats everyones thoughts.?

Thanks Kurt

lol

If there is no fuel, there is no fuel.....upgraded pumps supply more fuel........:think:

My thoughts, Don't run your car till it cuts out?

lol i'm thinking he's talking about fuel starvation when going around a decent bend/corner with low fuel

probuley would need a surge tank of some sort
or maybe a ralliart tank?

pumps not the problem, its where the pick up is thats the problem
tank wasnt designed for people to throw the car into a corner

Yeah this one. Is there any aftermarket tanks that fit right in.? So replacing the stock tank with a better one will do nothing.?

You can replace your stock tank with a Ralliart tank which has baffling to prevent fuel starvation. Otherwise, you could get an aftermarket surge tank installed, which is basically a tiny extra fuel tank of say 5 liters (for example) which gets fed from your main fuel tank. The fuel system takes fuel from the smaller one to prevent fuel starvation.

before doing all the upgrades, is the pump pickup too short on the standard pump?

Does the AWD tank work any better?

the problem lies in the orientation of the pickup. even though it's centrally located, instead of being forward or rearward facing it faces the passenger side of the car. so when you take a right hand corner at speed, all the fuel rushes to the passenger side of the tank, away from the sucking fuel pump.

I have noticed fuel starvation with more than 1/2 a tank at turn 9 at Wakefield.

I think it's time to really investigate mounting a surge tank...

cheers,
.wook

I get bad cutout on lefties with the 2nd gen on anything under 1/4 tank, sucks really. may do a surge tank if i turbo...... but a very slim chance.

Yeah my old second gen was terrible for that lol

As Paul said, if there is no fuel, there is no fuel simple really

When yo have a low tank, you corner all the fuel goes to one side of the tank Magna's do have a swirl pot of sorts but is not the best thus your pick up will be sucking air. You could set up pumps off a 747 for all anyone cares, it will not coax the fuel to defy the forces from the sharp turn

A secondary issue can be the sock on the fuel pump has fallen off or is very dirty thus is not getting the fuel, if this is checked and deemed ok, simple resolution is to not let your tank get so dry which is also good to prevent pump damage and sedement being sucked up

Another thing to watch, I have seen the aftermath of a fuel pump going off like a hand granade when it was run dry and exploded due to a spark internally ignighting fuel vapour, the internal of the pump has metal rollers that rotate to pump the fuel

Surge tanks are a good idea, you replace your std fuel pump with a high volume lift pump, you then plumb your return line into the surge tank, have the return from the tank return back to where the original return went, what happens is all the fuel being returned from the engine goes into the surge tank, the lift pump also fills the tank. When it is full it returns fuel back to the main tank as normal

Ok. If i wanna get a surge tank fitted to my car were do i get the parts and were can i fit this thing.? I dont wanna be looking for a ralliart tank.

you'll need another fuel pump, associated wiring, plumbing and a small(ish) container which will serve as the tank.

there's not a retail option that will fit without serious modification, so you might as well make your own (or pay someone else to do it).

^^^can't just make it as it needs to be engineered with the car

ralliart option works out significantly cheaper after all that

Well finding one would be a headache i reckon. Plus i wouldnt wanna know how much one would be new.? I reckon going to a performance shop or something like that would make up one for not a bad price and fit it.

Anyone here made up an aftermarket surge tank.?

you planning to put your car on the track alot?

Yeah soon.?

Anyone running forced induction that doesnt have a method to stop this fuel starvation is just asking to cook Pistons.:)

There is truck loads of room under the LHS boot floor under the car.

There are many tanks commerically available to allow either vertical or horizontal mounting.

They are easy to make, get some 100mm exhaust tubing, if you can imagine the tank being mounted under the floor length wise, the feed to your main pump (that feeds the engine) comes out the back. From the front you need at the bottom the fuel return from the engine and the feed from the tank. At the top you need the return back to the tank.

MAKE SURE you do NOT use the std efi pump in the tank as the feed to the surge tank MUST be low pressure and high volume

Also ensure that any hose from your new efi pump to the metal main fuel line is efi pressure rated.

I've never experienced any problems in my car, even when it was extremely low!...

if you take corners really hard then you will.

Hmmm, maybe I have just been lucky so far! lol

You just sent me a PM saying you want one because you corner hard.:nuts: Just fill the tank up and you wont have an issue.:hmm:
