I have a boat with a fuel tank of 60gallons.
My engine is now reaching 1000hours and its a 2008.
Its running a little bit "rough". I want to clean up injectors and intake.
Instead of removing all injectors a guy suggested me to remove the main gas line and use a separate line connected in a 5gallons of gas mix with high concentrate injector cleaner like P.i. Performance Improver Gasoline Additive from Amsoil.
High concentrate = 5gallons for all the P.I bottle. (Amsoil suggest 20 gallons for one bottle of P.i)Do you see any problem running high concentrate injector cleaner through the gas pump ?
(I mean can it damage rubber seals, diaphragm etc...)
Its a Volvo Penta gas pump
Once the 5gallons is burned, I will reconnect the gas line to the main tank.
In parallel of that I will Seafoam it.
