Difference in Fuel Pump

[UniquE]

Hi all, im having issues with the fuel pump.
Mine has the „2310061080“ pump installed. Don’t know if it’s the right one or not. Because we are planing a trip to Morocco I wanted to get it changed and bought „2310061101“ which is also for the 3F engine.

Toyota just gave me a call that the pump fits but is smaller than the one which has been mounted before and they don’t know if the new one will deliver less fuel.

I’ve searched the internet but both pumps are for the 3F engine.
Does it really matter which size the housing has? One of the lines also has a larger ID.

Thanks for the help!

Don't know the differences, if any, but I'd go with the one that was on there and working.

Kyosan TP-705 is the OEM

** I looked at that 61100/61101 and it's listed for 3F FJ62 General Markets 4/87-8/87 so it will be probably be fine.

Hi, yes I ordered the bigger version which was mounted from factory.

Still wondering what the difference is.

Man thanks though
