Well, when I open your link, I get posted with 7,99 GBP of postal charge, what is roundabout the same as the prize for the item. The political reason is sad enough 
.
In bad cases I will get charged german VAT (19%) on top, customs are usually negligible - if applicable at all for such small amounts of money. I know what I am talking about due to plenty of opportunity to learn about stuff like that from importing Corvette parts from the USA. Now the same kind of sh*t comes up for spare parts of my Spitfire.
But this is definitely not the point. I just explained (partwise in older parts of the thread) that for me (what is of course - as anything in public forums - only my personal opinion and preference):
If I had to suggest another "simple" (as mentioned, always a matter of inidvidual skills and preferences ...) way to overcome this, even a further mechanical relay would add a lot of safety here. Because with a stupid further mechanical relay, a coincidence of two faults would be necessary to cause a melted pump, instead of a single (!) fault as it is "state of the art" in E89.
The necessity of "OR"ing the two existing relays, forming a polarity reversing switch, to one additional switch for safety, persists in any case, unless you use two solid state relays (outputs in parallel) or two additional mechanical ones (same).

- it is technically second selection to use a solid state relay because of the considerable voltage drop
- it is technically second selection to use a simple N-FET (which is much cheaper, even two or three of them)
