Hi.

Oil pumps don't usually give trouble even if it's been laid up for some time.

Fresh oil, check the oil lines and you're probably good to go.

One thing you might want to consider is a precautionary oil pump bleed to get any accumulated air out?

There is a 10mm bolt on top of the pump just behind the tacho drive, remove that and watch for any air bubbles coming out with the oil. A slightly messy operation but worth it for the peace of mind.
CAREFUL with the bleed bolt, it's REVERSE THREADED so loosen it as if you were trying to tighten it if you know what I mean...

Its a good idea to flush the oil lines & make sure the check valves are working. The check valves are in the motor-side banjo bolts.
And take apart + clean the oil pump.

Those little plastic oil line washers are NLA. Stat-O-Seal washers are a popular modern alternative.
I get them from McMaster-Carr. They have reasonable prices but charge shipping.

Forum member bloop2 sells a T500/T250/T360/GT250 oil pump rebuild kit on eBay. It has all of the o-rings & oil seals.

Some members have a procedure to soften/rejuvenate the crank seals. They use a mixture of gas + diesel fuel, gas + Marvel Mystery Oil, or …
There are some forum posts about it.
