Honestly Eddie no I dont mate.

Follow the fuel line from the carb down over. You will come to the pump.

You could always take off the line at the pump that comes from the tank and see if there is plenty fuel there. That way you can isolate where the problem is.

Yeah Dave, Old pumps and tanks are an invite to aggravation. (especially here where they put too much lead in the fuel during the "old days" then it accumulated and released in chunks over time).

So if I find fuel in the line from the pump up to the filter then then problem is with the filter and needs to be replaced or cleaned if possible...is it the case she was choking due to being starved of fuel?

I hope this is the case, if it turns out to be just the filter or the pump or worst case the tank, I wont be too upset as it will be educational for me so I dont mind, I just cant bear the thought of doing some serious damage to the block or box ya know!!

gday wayne how well do 383s go i have heard a few contradictory reports some saying they are an awesome engine with a bit of work another fellow told me his /6 valiant was faster than his 383 superbee do they come with different performance levels? i have not had a 383 & have no idea how they perform so ithought you may be able to shed some light on the subject
cheers ian

Well when she aint sick she goes like stink mate..very quick.

I think the guy in the UK Tony had her set up for street drag racing, he put a new rpm gauge down on the console in front of the shifter as well!!

The 383 is 3x more powerful than the /6 tune for tune.

Wayne. Listen to what I am saying now.

Check that you have fuel from the tank to the pump. Forget about from the pump to the filter for now. 90% chance you have a dead fuel pump so don't waste your time.

If you find fuel both sides of the pump crank the engine a little and see if the pump shoots fuel into a bucket.

Ok Dave I will try that, thanks...

..by the way any news on the status with the noggin...I need to put your ass on a plane and fly you here for a weekend lad!!

I will not be allowed to fly until at least March next year.

They just cut my wages to half (to match my hours) so I have some strong incentive to get back to full time work. If it doesn't kill me that is.

I know the feeling.

Ok Guys,
Once again I think you have solved the problem for me.

I started the car and there was no problem, I only ran it for a couple of mins and all was fine so I looked under the hood and low and behold the was fuel in the filter 2/3 full like Dave said it should be all the time, now note that it was dry as a bone the day I had the problem.

So I was just about to jack up the car and get under to check the line like Dave said when I noticed a shimmer from the line from the filter down...Upon closer inspection the shimmer was fuel..I looked closer and realised the line itself has become cracked and was leaking fuel...

This is my theory based on what Dave said re Heat on the line...

When she is cold the fuel is in liquid form but after a while when the system heats up ie (the exhaust) the fuel vapourises in the line and escapes via the heat expanded line (where the cracks are)up to the filter(which is why it was dry the last time I checked the day of the problem.)

So as suggested she is spluttering and coughing due to lack of fuel to the carb.

I replaced the fuel line from the filter to the carb a number of months back because of the same problem, its just the other day when the problem occured I lost the daylight and couldnt see the problem with the fuel line. I will replace the fuel line when the parts store opens.

Does my theory sound plausable guys??

If so Im getting all mechanical...If not then Im a no good uneducated jackass!!

Thanks lads...I will update when I replace the fuel line.

The crack in the fuel line was probably opening up with heat from the engine.

Glad you found the problem and it was a simple one.

You see? You just have to use your eyes and a bit of logic. Saves you a fortune.

Thanks Dave...hopefully when I replace the line the problems will stop..Keep ya posted!!

Good to hear it Wayne!
