I have a 97 four winns with a volvo 5.0. I have a fuel leak on some device right behind the intake manifold. The hard line from the pump/filter assembly goes into this thing. it has a upper housing and the gasket between the two halves is weeping pretty well. I tried snugging up the bolts around the top. It helped some but not enough. Any ideas what that thing is? I'll get a picture shortly. Hoping to find a replacement gasket or whatever I need. Thanks
