It may explain why whenever I turned the electric pump off the pressure would drop to near zero for a couple seconds before recovering to the expected 4-5psi.

If we all changed to silico n for the coolant and SAE 30-R14 spec fuel hoses (or -R9 if you don =99t mind stiffer hoses) it would largely solve the problem of ethanol atta cking the fuel hoses. If the hoses are inspected carefully each annual for surface cracking or si gns of becoming =9Cstiff=9D I would personally be happy to go b eyond 5 years but that is clearly a decision for each owner and his inspect or in the UK.
