Carburettor fuel return line

[Dave A]

On my 1.3, with a pierburg, rally car there is a hose returning fuel to the tank. Given this is a competition only vehicle is it really needed? Can I do away with it without suffering any issues? Just about to replace all the fuel lines and I dont want to shell out on teflon hose and fittings for the return if I dont need too!

Where you planning on the returned fuel going? Pull it off the carb and see how much comes out...you will be surprised

[mowgli]

does the pierburg carb twin choke have a return? or is it a spare on the tank?

[mk1nova_rich]

Yep Pierburg has a return

[mowgli]

then bite the bullet & get some return pipe.

[mowgli]

oh, & re your sudden power loss issue that fixed itself, there is meant to be a small strainer where the fuel feed pipe joins the carb.

[Dave A]

Right so looks like it is needed then, thanks for the replies guys.

Mowgli yes aware of the strainer, but I think the blockage was upstream of that so simply not getting enough fuel into the carb.
