Hi
My friends , Do you use any glue when replace diaphragm ( not for diaphragm side , other side - in between sandwich plate/middle plate and inlet filter side , when replace two gaskets )
And use glue when fix unions ? (Inlet , outlet )
Regards
Sandun .

I have never used glue / sealant anywhere on the fuel pump, anbd have not encountered any leaks.

I endorse simmitc's reply … no glue or sealant.

I will also support the none use of glue of any type for this application - the joints if made correctly will be self sealing.
Petrol can effect the glue and ultimately cause leaks which can be dangerous.

Referring to Burlen's diagram , see link
http://sucarb.co.uk/su-fuel-pumps-spare ... arity.html
There are
two gaskets that could be described as " diaphragm sized ".
The item No 38 , nearest the base has 6 x holes for the fixing screws plus a slot to match the casting of the base internally.
AUA4082X non asbestos version
The second gasket Item 25 is plain , with 6 holes around the perimeter.
AUB 809X non asbestos version
Because you purchased the gaskets on Ebay , I've no idea of the source of the Supplier's goods or it's quality.
Have you questioned the Ebay seller , if you are saying the material is too thin and not fit for purpose ?
Buying another ( 2nd / second ) cheaper gasket for the filter side AUA 4082X may be an option , if you don't wish
to purchase an original from Burlen.
It is possible to buy sheets of gaskets paper ( of different thicknesses and size ) from which you can make your own gaskets. A set of metal punches ( to accommodate different screw or bolts sizes ) with a sharp trim knife would produce a nice clean gasket.
