Only a few gas tanks will be the original. Your truck sounds like it had the tank swapped from a different year or possibly the entire bed with tank were changed out at one point. 11/77 or 02/78 would both be model year 1978.

I moved this tread into the 720 truck section. Maybe you'll get more eyes on it over here.

Changing the fluid itself is more important. If you have more time to invest and you want to be thorough, then of course go ahead and put a new filter in. In my cars with an auto, I just change the fluid more often than is necessary and don't change the filter out.

I will be there ,, probably camping.

This Wenatchee event is coming up THIS weekend. Only 5 more days to go

I run 10w-30 in L-series engines. I also run ProLong engine additive that helps with keeping the cam and rockers in good condition and lasting a long time. I run 170 deg thermostat just to be slightly on the cooler side for the radiator. You might want to do the same in a hot climate.

It would be great to meet you at the park on Saturday. As for the first weekend of June, it looks like there is a group activity already planned down at the south end of Washington. https://zccw.org/events-calendar/

You could tow it up there. The main parking lot always fills up and others park along the street. You could just tow it up across the street and move the Patrol to one of the street parking spots.

It probably will not fit. I have seen the VG30DETT in a 510. It was an incredibly right fit. The VQ/VR is physically larger
