bravo 35 Report post Posted June 2, 2008 No, the newer cars often had in-tank pumps. Some cars had a transfer pump aswell. You might find there are some common pumps, but as you've found out, they often differ. If the pump is of the same type, you can mix and match. Quote Share this post Link to post Share on other sites
hotwire 352 Report post Posted June 2, 2008 Your 86 only has one pump under floor in front of L/H rear wheel - right? Your 89 may also have one in the same place - if so, you can use that as it is also the high pressure pump - the pick up pump (low pressure) is in the tank in that car. If the 89 only has the one pump intank then that is a high pressure unit Quote Share this post Link to post Share on other sites

hotwire 352 Report post Posted June 3, 2008 Yep 86 should only have the one external. yes can put the 89 one in place of. Not designed as servicable - crimped together I can supply one if you wish - PM me if you want one Cheers Quote Share this post Link to post Share on other sites
