Thread: V8 Fuel problems.

A stage 1 is horribly complex , so you will have to get the CDrom manual and a number of electronic measuring devices. NOT.

You appear to have fuel starvation.
New filter
clean the filter in the bottom of the Facet
maybe lag the fuel pipe in the engine bay
check that the fuel cap is venting properly
Facets usually work or don't , needing a stiff kick to start ticking again.

<span style="color:blue">hook up a fuel guage under the bonnet and run the guage up to the wiper
so you can see it as you drive.....


then drive it and see if you are running out of fuel pressure at high revs or not....


that would be the quickest and cheapest option of diagnosis....



if your pressure drops at high revs but is ok down at low revs....
it could be a simple blocked filter...or a fuel pump....

start there and let us know the results....
if fuel is ok....then we start to check the ignition sysytem....</span>

Sounds like a recipe for self-hypnosis if it's raining! :roll:

We put refilled/made sure there was fluid in the carbs and checked the diaphrams and they were both good.
I bought an autometer fuel pressure gauge off a mate (new $20 ) so i'll fit that and see what happens.

Thanks for the replys.

<span style="color:blue">carbys......?
i was thinking injected...... ops:


could simply be the float levels not right....
it wont let the needle drop enough to let the fuel into the bowl fast enough....
when you are on fast throttle...once you use up whats in the carby...
it could simply not be getting the fuel in fast enough....

ok below 2500rpm.......though.....but anything above.......</span>

People allways overlook the simple stuff first.
Have a look at the vacuum advance unit on the side of the dizzy , the diaphram can get ripped or weak after years of use and is the most common cause of engine faults in most of the cars I have worked on over the years.
Take the small pipe off the carbie , put the end in your gob and suck , if it is stuffed you will get no resistance , to be sure take of the dizzy cap and watch the base plate , if it moves when you suck it's ok if not it's stuffed.
and all you dirty mined buggers get out of the gutter :roll: .

Hope this helps mate :wink: .

I had a bug stuck in one of my fuel lines to the carby once. It only got worse the faster I went. The landy mechanic I saw could not stop laughing when he told me what was wrong. It happened when I reconned the motor and had the carbs off to do so. Bloody thing crawled inside the tube and died. Due to the motor being new I thought it was a prob with new motor.
It would run ok until u wanted speed then would not go until u slowed down.
Never mind we all learn from these little hassles
I can laugh now but it was a pain then

Hi Dave
Have you checked the pick up in the tank??????,its the first place to check for fuel starving.If it aint coming out of the tank fast enough,everything else downstream can be mistakenly blamed.
Goodluck
