Clean, Clean, CLEAN!
Fuel contaminants like dirt, rust and scale are a primary cause
of in-tank fuel pump failure, and they can cause the replacement
pump to fail prematurely. For a successful installation, you
must keep everything totally clean--start to finish.
1. Clean accumulated road dirt from top of fuel tank, taking
special care around the pump access area. (Cover fuel inlet
tubes first.) Also clean tank filler pipe.
2. Inspect the fuel strainer for stains from rust, clogging
from dirt, and slime from water. (Some fuels contain up to 10%
alcohol, which attracts water that can accumulate in the tank.)
All tanks must be drained, flushed and dried before installing
the new pump. If the interior is rusted, the tank must be cleaned
and inside surface sealed, or it must be replaced.
3. Replace pump on a clean work table, or lintless shop towel.Electric
fuel pumps are made to extremely close tolerances, so are easily
damaged by the smallest contaminants.Keep your hands clean.
4. Keep replacement pump in its package until you're ready for
it, and leave caps on inlet and outlet fittings while installing
pump in hanger.
5. Install new strainer. Make sure its retaining clamp fits
snugly on the pump inlet to prevent contaminated fuel from bypassing
6. Discard the old tank seal and replace it with a new one any
time the lock ring is removed.
7. Protect filler neck and inlet/outlet openings from dirt when
reinstalling fuel tank in vehicle. Stuff shop towels in tank
openings and tape over fittings until ready to reconnect lines
