    How to install strainer
    Asked on 1/26/2012 by Gilbert from Apopka, Florida

      You'll notice that the tank outlet is a larger round cover with a nozzle coming out of it. At the base of the nozzle (which you can't see too well with the hose attached), there is a hex head that's part of the nozzle. Using a 17 mm deep socket and ratchet or 17 mm wrench on the hex of the nozzle, turn counter-clockwise to remove the nozzle and strainer assembly. Make sure you have a container underneath the tank. The bottom of the strainer assembly is below the level of the nozzle so, some additional fuel (a small amount) will drain from the tank when the strainer is removed. When you get the strainer out, inspect the strainer for debris built up on the outside of the screen. You may find some debris at the base of the strainer which may be cleaned out using a small probe. However, be careful not to poke a hole in the strainer while you're cleaning that area. You may clean the strainer if it is clogged by backflushing fuel or carburetor and choke cleaner back through the nozzle. You may also blow low pressure (10 psig max) air back through the strainer nozzle to loosen debris from the screen. If you discover any holes in the screen during cleaning, the strainer should be replaced. Install a new O-ring seal on the strainer. Coat the seal with a small amount of moly grease to lubricate the seal. This will keep it from binding and getting cut or abraded during installation. Install strainer and tighten using 17mm wrench or deep socket. Attach the fuel line to the strainer nozzle and fuel pump and tighten hose clamps.
