fuel starvation
sonic - 7/7/05 at 10:06 PM

If i corner fast in my MK with half a tank or less my engine dies until around the corner and then pics up and off she goes

Anybody else noticed this?
My mates pinto engined MK does the same

Any solution recommended!
Odviously a baffled tank would cure it but wondered if anything can be done to the standard one

Right or left hand bend, or both? How long? What engine?

very common on kit cars cus usually the feul tank is flat and wide. Mines got a center divider and a small surge chamber on the bottom but still does this on long corners with less than half a tank.

I'm thinking of changine to a column sender then just stuff a load of baffle foam in the tank.

Right hand bends
Depends on the length of the bend as to how long it lasts

16 valve Vauxhall running injection

The tank is ally and has a extension on the right bottom to catch feul to try and stop this but odviously it doesnt work

Don't know a lot about it but fitting a swirl pot might cure this.

You'll need a high volume, low pressure pump to fill it though!

HTH,

I think I'm right in saying that the high pressure fuel pumps used in injection systems are lubricated by the fuel, if you starve the pump it will wear very quickly. I'm with James on this one, fit an external swirl pot.

Sonic,

where did you get your tank from?


sonic - 8/7/05 at 07:28 PM

its a custom ally tank made by MK

I suppose the other cure is to keep the tank over half full !!!!

Cheers

Given the flow rate of high pressure pumps (C150 litre or 33 gal / hr) surely it would be OK to feed the swirl pot by gravity from the main tank and by the return from the HP pump. The swirl pot would need to 'overflow' back to the main tank.
Or have I missed something again.

I've seen swirl pots plumbed in between tank and feul pumps in several acations, but nearly always the swirl pot is below the level of the tank.

Mount it at floor level, can't see a problem there.
