Barry Kemp Posted June 12, 2020 Report Share Posted June 12, 2020 A quick question (well, two actually) about refurb of an original Herald AC fuel pump. The refurb kit doesn't include the fibre washer that sits under the spring retaining washer of the new diaphragm. It does contain a 'hat-shaped' rubber washer. Is this a replacement for the original flat washer - or for another type of pump? If it isn't a replacement how critical is the flat washer -should it be replaced? Also, prior to re-fitting the pump, is there a knack to aligning the curved arm of the pump back into the block - or is it blindingly obvious !? Many thanks.

Colin Lindsay Posted June 12, 2020 Report Share Posted June 12, 2020 I'm wondering if the 'catch' of the retaining arm is meant to sit down inside that hat-shaped washer; if you imagine it as a fibre washer with a bit added on it makes sense, so that the flat bottom sits in the same way as the original washer but it's now got a snazzy top-hat shaped bit into which the clip fits?

Pete Lewis Posted June 12, 2020 Report Share Posted June 12, 2020 the top hat is used as an oil seal on some pumps , no idea if its universal have some odd memory of the change from flat operating to round rod WSM is of no help very limited pump clues Pete Link to comment Share on other sites More sharing options...
