I have used many brands over the years for these rigs...
I have mostly used the AC Delco pumps and buy them from RockAuto.com... they usually have been the cheapest prices for them.
I have used the Airtex pumps in the past (customer was on a tight budget) to only have to replace it a year or so later because the gauge issues continue to return and the pumps started to get noisy...
also... be prepared to have to change the electrical connector, as most of them for those years have a replacement eletrical plug that needs to be swapped out.
but all in all, with an empty tank it only takes about 30-60 minutes to replace...
