C5 Corvette installation instructions

1) The tank modification

The windshield washer tank will need to be modified to deliver the fluid to the pump

assembly. The modification entails drilling a ¾ diameter hole in the bottom of the tank,

its lowest rear point, then installing the supplied bulkhead fitting. The fitting will be

installed as follows, the main body of the bulkhead and Teflon washer will be inserted

from the inside of the tank out, then once through, install stat-o-seal washer, then

stainless washer, then nut. Once nut is threaded.. tighten assembly. Some tips for

doing this are, if a small length of wire is fed from inlet to outlet, the fitting can be

slipped on to the wire and guided into place. Once the nut has been started, grabbing

inside of fitting with needle nose pliers to hold the thread, then use a wrench for

tightening the nut down. Lastly an inexpensive ¾ drill bit for making the hole is a

simple spade wood bit available at most hardware stores. Its only plastic. At this point

install 90 degree fitting pointing toward tank. The short length of –6 hose which is 18

inches will be attached at this point. It may be advisable to test the tank for leaks at

this point using water. Next is to drill hole into cap and install supplied vent. Drill a

smaller diameter hole, and press vent in. 3/8 should do it. Next is pull motor from tank

and install the supplied brass tank plug into rubber grommet. Motor can be used with

an external tank available separately. Also replace low level sender grommet with

supplied new one.
