Hi

I would like to know any problem may appear if using different fuel tube size. If we go for an engine with carburator running usually with 1/4 fuel tubing and got 2 wing tank :

System layout as follow
wing tank fuel pickup : on 1/4 tubing, goes into a 3/8 fuel filter
go into a 3/8 fuel pump
go into a 1/4 fuel selector
an 1/4 line up to the engine.

Basically, is a mix of 3/8 tubing and 1/4 can cause any issues ?

Thanks
