I never bothered with a return on my 1300 converted 1ltr.

You shouldn't really need one. A certain A-Reg (now rolling shell for £175) that was once a 1.0L doesn't have one, and that ran a 1300 with a 32/36 DGV Weber with standard mechanical pump. I know that the original Peirburgers often leaked like sieves when presented with a little fuel pressure, where the Weber was more than happy.

What carb are you using on the 1.2?

i have to do something as fuel comes out , at the moment ive put the return to a jerry can so i can move the car about.

yes its the peirburg single choke, the engine has done 27k proven

You need to bung up the return pipe from the carb. A bolt with a long shoulder and a jubilee clip should sort it.

Ugly, but effective

[mk1nova1.8]

what happens to the excess fuel ?

[C612DNM]

Nothing. theres a pressure build up in the carb. The standard pump can produce about 2-3psi tops from experience. Nothing to worry about.

[mk1nova1.8]

okay will give it go tomo , just cant be doing with it flooding and not starting and with it getting colder im hoping to get all the messing around sorted and get it mot'd.

[mk1nova1.8]

cheers for your help

some people have been known to tee it into the tank vent pipe, but i don't know how effective it is in the long run

[C612DNM]

Could work like that. Personally, I'd plug it.

[mk1nova1.8]

i did have a look at the vent and thought about that will bung it and see how that goes

[mowgli]

i'm not sure it will be effective. they fitted a return for a reason.

because it was easier than a pressure regulator on a p-berg, or worse : GM Varijet!!! They used to pour juice down the inlet if the return blocked.
