Welcome to the forum.
A great source for authentic Toyota parts at much better prices is Amayama.com. I use them regularly (in fact, just got some parts from them this week) and they are efficient and have much better prices than local Toyota dealers. These are their prices for the OEM Toyota fuel pump:

Personally, I've never found Amayama to have the parts I wanted in the UAE. I have always ordered from Japan or Australia. The listed price from Australia actually works out to be the most accurate by the time you add the postage costs to the listed price from Japan. Shipping in Australia would only be around $10-15 on top of the $468.98.
