Olds 403 6.6 Ltr Water standard duty water pump as found in the 77-79 Firebird TA series & many GM Vehicles sold in tighter USA emission states .

Comes with a gasket also.

The Olds is a "6.6 Litre" .. is often confused with the  6 ltr 400 Pontiac of the same years.

To help it.. the Olds has the Fuel pump on the RHS.. US Passenger Side ..  and the Starter on LHS..  

  The Pontiac has the Starter on the same LHS.. but the Fuel pump on the LHS.

This is for the Olds..   Its also has a pipe coming up from the water pump curving into the water neck outlet.

For cars originally with or still with air conditioning.

NOTE: Every belt driven water pump has a weep hole that might leak a little in the beginning. Some seepage from the weep hole is normal during the break-in period (about 10 minutes), and does not indicate a defect.
