I have a poly tank and a 350 SBC, has anybody increased the size of the fuel pickup? 350s are 3/8s and from what I can tell the poly tank is a 1/4.

Thanks,

I simply unscrewed the elbow from the top of the tank last night, looks like there was a 3/8 copper line soldered into the other end of the elbow

I will be replacing the elbow with a 3/8 barb / 1/4 npt elbow, pressing in a 3/8s fuel line and should be in much better shape,

the actual orifice size of the existing barb is even less then 1/4 :(

the fact my pickup tube was rotted in half and in the increased size do something better

to be a little more accurate a 3/16 drill bit does not fit in the orifice of the existing barb
