Yes, but I won't need to do several fillups on diesel before my converted truck is back on the road, so the math doesn't favor buying a second set of goodies (FPHE/Racor/hoses/etc.), locating and buying a suitable tank, and doing the setup again...

Not to mention it would take way more time than simply changing my WP.

So, thanks for the advice, but I still think the test was worth it. Especially knowing it was going to be for a short period of time, and in summer.
