Is the hose clear? Sounds almost like you have a check valve in the line.
Did you make up the hose by putting on ends? If you made the hose or had
it made to length, there is a possibility that a "donut" has been cut out
of the hose side wall making a flapper valve. Happens when someone
doesn't use a mandrel.

The hose was from a mail-order racing parts supplier (Summit Racing, IIRC)..
It is one of their stock lengths. No idea if they use mandrels or not.
