Fuel tank question...

[CSIPSD]

Or fuel tanks so to speak...

Do the OBS trucks have the same mixing chambers as the superdutys? My caulker is telling me that his OBS truck (with 580k on it, never had anything done but a HPOP and rear axle!!!) is having a hard time with the front tank?

I've never dropped an OBS tank.

Mixing chamber? Like the one you remove in a SD tank when you do a hutch mod? If that's what you're talking about then no. All the obs has inside the tanks, front and rear is the pickup tube with the "umbrella" at the bottom.

The OBS pickups have a rubber valve in case the normal pickup gets clogged, if the rubber fails, then fuel cannot be drawn from the last 1/8 of the tank. Only other problem would be the selector valve has failed and does not transfer tanks.
