Rodbr Posted July 24, 2021 Report Share Posted July 24, 2021 Does anyone know off hand the correct dia for line to pump and pump to carbs. i.e what size for the AC pump inlet and outlet. I think 1/4 to carbs and 5/16th tank to pump Thanks. Rod Quote Link to post Share on other sites

BlueTR3A-5EKT Posted July 24, 2021 Report Share Posted July 24, 2021 Which car? Yes always 5/16” tank to pump via the petrol tap. For pump to carbs. Depending on inlet pipe types fitted to the float lids of the carbs. It can be either be 1/4” for all push-on connectors or 5/16” if you have banjo fittings.

mikej Posted July 25, 2021 Report Share Posted July 25, 2021 You may want to specify ethanol resistant SAE R9 hoses while you are about it, I think RTR sell it as probably do other suppliers. Quote Link to post Share on other sites

mikej Posted September 13, 2021 Report Share Posted September 13, 2021 Yes indeed if it's available but R9 is not withdrawnand still suitable. I'd realy like to know why some ancient fuel hoses with no specification marks at all are behaving realy well whilst others of the same vintage (ie., the ones on my wife's Mini), have gone all soggy.
