Fuel pump unit - is there a hose barb under here?

[danielschudel]

Just finished a smoke test and I found a good leak in the fuel evap system. Got a rotted tube on the fuel pump and housing unit. The tube seems to loop back withing the housing unit.

I don't want to jump into tearing apart my daily driver quite yet.

I'm guessing that the red arrows point to a hose barb under that hose. And getting the old hose off and new hose connecting the two hose barbs is the right plan.

But - can someone first confirm that there truly is a hose barb where the red arrows point?

The answer is "yes" - hose barbs at both ends. But for replacement hoses: 5/16" is a tad too tight and 3/8" is too loose.

8mm? 5/16 is 7.9mm 3/8 is 9.5mm
