Hi,
a replacement pump can be had for not a lot of money - bought mine for 56 Eurobucks plus shipping, same unit as in all your pictures, seemingly the only pump you can get these days.
Vendor was tshopabs on e*ay, however it's listed they ship only to Europe. They do stock just the pumps without the whole plastic can/fuel level sender, as well, too, for around 30 Euros. IMO, ordering a whole new assembly makes more sense, you can mix and match too...if your preferred USA vendor doesn't have stock, maybe worth a try to shoot them an email?
BTW, I prefer a different layout
than what's shown here on page 5 - if you use just a little more hose and let it bend at a slight angle (most hoses come rolled-up, anyway), it will easily clear the outlet pipe as that moves downwards on installation. Main benefit this way is that the hose doesn't have to twist (the loop from the tee to the outlet) and there is no mechanical stress on the short hose connecting the tee and the pump as there would be if the tee and the pump touched (would stretch one side and kink the other since there is hardly any free length).
This also allows the hose not to have to twist at all - you'll know what I mean if you used the stiff PU tubing...a good thing, as any twisting will make it kink way more easily. The last pic is fully compressed, on the mechanical stop. IMO it doesn't compress that far on installation.
No need to cut anything much, I'm using a metal Tee instead of the plastic ones. Reason being, it's way shorter - and seals perfectly.
You can rotate the pump motor in the plastic can, as well - making it easier to align the hoses to your liking. Having the outlet at the right place makes things simpler.
Thanks for all the info, people! Made it dead simple to perform the mod...down to the exact tubing length
Now if I knew what relay to get, exactly...
Regards
