Puel pump is on its way out. Diaphram pump fitted?

Fix it imediatly, otherwise you'll destroy your engine having petrol on the oil!

X2 fix it immediately it will destroy your engine. Do not drive the car.

Changing the pump over is a pretty straightforward job. Should only take 1/2 hour or so.

Also dont forget to change your oil and filter after you fit the new fuel pump, to remove the contaminated oil.

how dangerous is it to drive? got a feelin it may hav been like it a lil while and i got overseas friday and cant afford not to hav the car b4 i go.

How much will it cost for a mechanic to fix it?

also could the fuel pump bein gone the reason i get cr@p fuel eco?

Very bad, dont drive it. Any oil with petrol in it wont lubricate, i could spin a bearing, or damage cam, rockers etc.....

ahhh bugga.

How much u think it will cost to get fixed?

Post by **gorgie2006** » Wed Mar 12, 2008 10:23 am

also would it be worth up gradin it to a better performance pump?
if so any names?

Post by **Mike_1324** » Wed Mar 12, 2008 10:30 am

A pump, an oil filter, and oil is all it'll cost

Pump will probably be afound $40,-

Its worth fixing now rather than having a dead engine, i can tell you now which will cost more to repair....

Most new pumps have a little overflow tube that will leak if the diaphram breaks, rather that it flowing into the sump. Much better idea!

I'm not aware of a "performance" pump.

All pumps (factory included) have the overflow but these can become plugged.

Very possibly, if it has been leaking fuel into your motor instead of burning it. But if you have been loosing that much fuel (as a 42l tank in a zook that only gets 200km means more than 20l/100km) you would have had an overflowing sump, and would of most likley done some hideous damage to your bearings/rest of motor. That sort of fuel consuption for a standard (or near standard) sierra is pretty bad.

sorry i get 200km b4 it gets to the empty line. which means ive got 10L left so im only getting like 15L/100km.

Wen i first bought the car just after i got my Ps it was only gettin 100km b4 empty line then i got the carby redone.

Suzuki fuel guages are well known for being unreliable. Mine only ever reaches 3/4 and i can drive for over 100km after it has hit empty. The only way you're going to work out an accurate fuel usage is to:
- Fill the tank up full
- Take a 10L jerrycan along with you
- Drive till the car runs out of fuel and record km's
- Use jerrycan fuel to get to nearest servo
- Fill the car back up to full

Then figure out how many km you got out of xx Litres it took you to fill ya car back up with (-10L that you added from the jerrycan)

Then learn to drive off the odometer reading since you now know approximately how many km you can get before your run out of fuel.

Well thats how i do it, i've been stranded too many times for trusting the guage

umm i fill it and the petrol pump says i got to pay for 30Ls wen it clicks off and the OD says ive done round 200km.
So i think my eco is bout 15L/100km
well thats how i work out mine

Bit of a thread hijack but my fuel pump flogged out up at toolangi on a sunday recently and had to replace it with an electric pump as nowhere was open that sold the 1.3 mechanical pump. Wired it up to the coil and ran it through the stuffed pump so that we could still get a fuel return working back to the tank.

Question is if my pump being stuffed, will i be getting fuel flowing into my oil if the electric pump is still plumbed up through it? The pump was completely stuffed ie pumping but 0 pressure.

Post by **Mike_1324** » Thu Mar 13, 2008 6:08 am

Most probably.

The pumps are simple, they are a pair of pressure valves (like a heart), with a diaphram below, controlled by a rocker, driven by a push rod, off a cam lobe.

Pretty much only two things can go wrong..... a valve sticks, or the diaphram breaks..... if its the latter, you will probably get a bit of fuel down into the oil.

The other thing you need to be careful of is the pressure. The mechanical one supplies something like 3psi? The electric one may supply more? It will cause flooding and may help rupture the buggered pump more.

layto you right but for one thing..
it is a vitara not a sierra with a vit engine as written in the first post....
so i think vitara tanks were around 54 lt....... depending on swb or lwb....
still 200ks to a tank goes into the holy crap category...

cheers mark
