Hey guys, I've been reading these forums for a while now and this is my first real post.

I have recently done a 1.4 cvh to 1.6 cvh conversion, I replaced seals, bearings, checked for cam and crankshaft wear, generally replaced anything that was worn down. The 1.4 had a Weber 28/30 DFTM but I am currently putting a economical Weber 28/32 TLDM which was fitted to escorts after 86 as an option instead of fuel injection if i'm correct.

I'm lead to believe that this TLDM doesn't have a fuel return pipe attachment so I am supposed to use a 3 piped fuel pump (one of the pipes is for fuel return I guess) which I have already ordered.

My car is currently using the 1.4 carb, and it doesn't run very well with it so i'm borrowing a friend's car and not using it at the moment.

My question is, how important is the fuel return pipe? Should I just put my TLDM on there without the fuel return pump and use it for a while or will this cause some kind of fuel flooding in the carb/engine?

Thanks!

Hi , you can use a T SHAPED connector so you have a return flow to tank
the return may need a little restriction so the flow favours feeding the carb first
or else you will get starvation,
I have a T piece that has a drilled out carb jet in it, for the return flow
that's the sort of thing to overcome the problem
I think they made a T piece designed for that precise scenario,
if you have no jets , something , just to restrict return flow abit

Thanks for the fast reply. This is a good idea and will give it a go if the pump I have ordered doesn't seem to do the job, or if it takes a long time to arrive I'll put a T junction in there.

Just a quick question, would a Y junction be a good idea since the fuel going in one direction would find it easier to follow the path towards the carb rather than the fuel return path?

adding a slight restriction to tank return takes away the doubt good luck

ok thanks
