petrol return pipe ?
as you know my meteor has an electric fuel pump,
I am thinking of returning it to the origional manual pump but there is a pipe plugged with a manifold stud and I dont know where it should be connected to.could it be a return pipe to the petrol tank ?
please see pictures.
capped off fuel pump with pipe in questionn
feed to electric pump with primer bulb added
connections to pump
obviously the old inlet pipe has been extended via the primer bulb to the electric pump then a pipe go's from the electric pump to the carb so where do's the blocked off pipe connect to ?
any help would be appreciated

what difference would it make if the flow and return pipes were swopped over .
the reason I ask is that after looking at the diagram way2go posted and this picture.
it would seem that the garage may have plugged the origional feed pipe as it seems to be the right length to go to the fuel pump ( black rubber with yellow writing) whereas the other (fabric ) pipe seems long enough to reach the carb suggesting it might origionally have been the return pipe.
also on the diagram it says the suction ( input ) pipe should have a yellow paint mark and the plugged pipe has yellow writing or is that just coincidence

If your suspicion is correct then the feed (old return) pipe now would not be filtered from the tank. However IIRC there is a built-in filter in the SU pump so this would not be a major problem.
BUT, if you look at the diagram, the end of the return pipe is higher in the tank than the feed so your usable petrol volume will be less as there will be a considerable volume that you cannot therefore access.

Yes I saw that, well the cars not running out of juice before it gets into the reserve
Do you know if the flow and return pipes are the same bore ? Both pipes have yellow writing on them one is citroen the other is another make.

had a little look around the carb today and now we can all play spot the difference.
Haynes manual showung flow and return pipe fitting at carb.
( bottom left pic 14:4)
and now my car
so there is no return pipe fitting on the carb, just a hole where it should be.
what affect will having no return pipe have on the car ,
I mean obviously excess petrol will not be able to return to the tank
but what else will this cause
( there is quite often a whiff of petrol on start up but no sign of any seepage or leak anywhere

/\ none. The return is for two reasons:
1 it's for emissions compliance, to get fumes back to the tank
2. if the float gets stuck down, then the fuel keeps pumping into the float chamber, and you might hope that it will go that way rather than every other way it can.
In the good old days, there never was a return from carb to tank.
EDIT: IMO that electric pump is a fire hazrd. If I were you:
(a) I'd check to see if the mechanical pump is working. Start the car to get the float chamber full, then switch off. Disconnect the feeds to/from the electric pump. Reconnect the feeds to/from the mechanical pump, with the output going to a petrol can. Keep a funnel handy to gravity top the float chamber up (if you want to play for several mins with the engine running), then start the engine to see if the mechanical pump works.
(b) if the mechanical pump works, take the carb off and clean it out. Then reconnect all the feeds to/from the carb.
Now you will have a proper 1.6 BX again. Take that electric pump to the forest on a full moon, and sacrifice it to the fire gods.

I meant to say, sorry if I ask a lot of what might seem "obvious " questions.
lack of self confidence is one trait of surviving P.T.S.D. I have never been able to shake.
