Over the past few months I've had issues with the 72 Notch.
Mostly fuel related.
This week I put the tank back in after cleaning it and the filter in the outlet.
Last night I put in a new fuel pump.
This morning when I got it started and running, as soon as I switched the ignition off fuel started trickling into the carbs then flowing which flooded them.
I've had an issue with starting the motor after it has sat for a few minutes after switching off for a while now, so it seems like it must have been happening with both previous fuel pumps as well.
The Gregorys manual mentions a shut off valve in the fuel pump or carb. As this is not the original dismantlable pump that would have come with the car would I have to put a fuel shutoff valve in the line from the pump to the carbs? Or is there a problem with the carbs?

There is two different pump rods you can get - a long one and a short one.
There could be a possible problem if you're getting too much pressure with the long one?
I'm hoping that makes some sense to you..

shut off valves are normally in the carby.....

check the needle and seats in the carbies

Would that be the "electro-magnetic pilot jet shut off valve"?
If there is no connection to them both would that be the problem? Guess I'll have to check that they are working.
Any tips on how to test them

turn ignition on and pull the lead on and off you will here the solenoid clicking in n out

but that don't have anything to do with fuel flow


is that china pump you have installed might not have the check valve in that sitting properly

Solenoids are working.
Pump box is labelled Brazillian. A Brosol. Does this type have a check valve?

they all have a check valve to stop flow

are you parking he car flat and level

It's up on jack stands at the moment but is level.
Fuel even runs in with the line off the pump and a bung in the end. Tried the old worn pump and it does the same.
Will probably decide to give the carbs a good overhaul before long anyway. Will leave it for now.
Just needs a lot of cranking to clear the fuel before it starts.

check the gasket spacer under the needle n seat valve or add extra spacer this will lower the float level and ensure the seat stop the fuel flow

take the fuel inlet line to carbies of the pump and fill with fuel after you have adjusted the float level and hold up above the carby level high so gravity allows fuel flow to carbies this will determine if the are leaking or not

if not leaking then something wrong with the pump

Cool. Will follow that up. Thanks

Sometimes when all else fails to make the 50 yr old stuff act like new no matter how much you try, other methods might be considered.
Like an inline LPG-style fuel cut-off solenoid just after the fuel pump.........

I have had a few fuel related issues with a few cars of late. Have you only idled the car or have you driven it?

A friend and I were working on my ghia 36hp and it idled beautifully for a short time before flooding. Checked the float level and that was okay so worked out we were getting too much fuel pressure, added another gasket to the fuel pump and hey presto!

My daughters '73 fastback has also had a lot of fuel issues in that it is using a lot of fuel and has a horrible fuel smell but no obvious leaking. Pulled the carbs off and where the two faces meet was noticeably warped and buckled so have acquired two replacement carbs and now getting them re-kitted before trying again.

PS: I am also looking for the rubber spilltray and outer seal that goes where the fuel filler and fuel flap is for her car and the outer rubber seal. Boris has the spill tray but no seal and ISP West has neither - any leads?

Try VVDS

Got the old fuel pump out last night, the one that was on the car when we got it, that I changed early in the year. I'm going to give that one a try today before I pull the carbs off.
I have tried taking the outlet pipe from the fuel pump off as soon as I turned the motor off to see if the fuel still runs into the carbs with no fuel pump pressure. It does still run in.

Ok so if fuel still running from pump the check valve in the pump is stuffed

Pulled both carbs out Yesterday. Crap in right carb needle and seat (see photo). Nothing visible in left carb but cleaned out anyway. Haven't altered anything settings wise but will adjust once I get a couple of rebuild kits.

That will do it every time

Looks like you need an in line filter before the pump

Its got an in line filter after the tank, tucked up in the space near the auto trans. There is also the mesh filter in the tank. I'm tipping this has got in the line when the fuel pump has been disconnected to prime the line when the old pump was not working properly, or when the fuel pump has been changed.
Have to put some fuel in the car to see if the flooding has stopped. Will get on to that tomorrow.
