Ethanol In FRP Tanks Manufactured Pre March 2003
July 21, 2010 by Jennifer Davies
Questions have been asked regarding the suitability of FRP tanks built to originally to take unleaded fuel to handle ethanol blends.
The information that we have from our resin suppliers is that these tanks are capable to handle 10% ethanol blends subject to 1]the blend not containing more than 10% ethanol and 2] that there is no phase separation in the tank due to a high water content.
There is a possibility that ethanol blends over 10% and phase seperation will soften the resin in these FRP tanks which could lead to failure.
We have attached information below regarding this issue.
