Another issue.
I have an external Wallbro-Wep11 6V petrol pump. It was New Old Stock. Before the summer I tried it and it did nothing. Upon opening I found the bellows completely gone ( to goo, and never contact with any petrol). I tried ordering a replacement bellows in a revision set, but do not get replies from the vendor. I decided that I will try to print them on a 3D printer and am therefore testing different filaments that are flexible and petrol resistent (ethanol and additives). They are now 8 weeks in petrol and I see no difference yet. I was told to also try teflon and maybe Viton ( if available in filament for 3D).
Any thoughts? Did somebody try this? What Alternatives? ( SU 6V to low pressure, maybe a Carter?)
I could replace the mechanical one but like the electric one beter as it primes)
Hope to hear
regards ( met vriendelijke groet)
