Please check notes in each part listing to ensure the Washer Pump Repair Kit is correct for your 1978 GMC K15 PICKUP with a 6.6L 400 4BBL OHV engine. ANCO & TRICO are competing brands, and each brand's Washer Pump Repair Kit may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Washer Pump Repair Kit fits only certain 1978 GMC K15 PICKUP models.

Clicking a "More Info" link will display a picture and/or other details about that Washer Pump Repair Kit in a separate window (you may need to turn off your pop-up-blocking software for this to work).

After choosing a Washer Pump Repair Kit, click the "Add Part" button. Shipping costs will be shown on the Shopping Cart page.
