2011 Peterbilt 389 fuel won’t stay equal

[Lonestar10]

its against DOT regs unless your truck is diesel. to many trucks hit stuff on the roads and dumped their fuel everywhere so i high recommend not even giving the thought another eyeota of time.


went read it i guess diesel tanks are exempt....ok but here it is.

Drains and bottom fittings.

(i) Drains or other bottom fittings must not extend more than three-fourths of an inch below the lowest part of the fuel tank or sump.

(ii) Drains or other bottom fittings must be protected against damage from impact.

(iii) If a fuel tank has drains the drain fittings must permit substantially complete drainage of the tank.

(iv) Drains or other bottom fittings must be installed in a flange or spud designed to accommodate it.

so if you can keep your fittings under 3/4 inch when measure from tank bottom to bottom of fitting then i guess it can be done.
