Homelite pump

[topgut]

Picked up a water pump recently.
UT 01297
S# 32360222

Not marked with much lettering but I think its driven by an XL power head.

Anyone have info on these pumps like an IPL ?

Thanks

EDIT: I have found out its a XLS 1.54A or XL pump.

Anyone know when these were made?

I have the IPL that covers the XLS 1 1/2 series pumps and Vol 6 of the Homelite Shop Service Manual which covers the pump unit and the engine unit. PM me...
