Hi - on my 87gt I have found for a while that the oil pressure gauge needle dances around and I am wondering what causes this and is there a fix.

any opinions are always welcomed

Thank you - I know the fierostore sells them - but does anyone have the ac delco part number - so that I maybe able to cross reference one and get it in the u.k? (trying to avoid paying too much shipping from fierostore)

thanks

I would highly recommend switching to the more reliable, less expensive, and more widely available '88 Fiero V6 sender while you're at it. The only down side is that swtching to the '88 sender will also require you to install a different connector. The Rock Auto web site is a good place to look up part numbers like this, even if you aren't planning to buy from them:

'88 Fiero V6 Oil Pressure "Switch": ACDelco #D1808A (GM #12555492, 19244501) $24.79
'88 Oil Pressure Switch Connector Pigtail: ACDelco #PT1951 (GM #88860506) $9.19

'87 Fiero V6: ACDelco/GM #10030963, 10045775 (per ACDelco ... may be discontinued)

right - so a 1988 sender will fit an 87? is it just a straight swap with the connectors?

thanks so far

The oil pressure sender and its connector changed in '88. Everything else remained the same. The threads are the same, etc.

The "old style" sending units (the large ones) are pricey even here in the United States, with some stores charging in the neighborhood of $50 USD. They're well over double the price of the '88 sending unit, and the '88 sending unit is much more reliable. They can be found cheaper by looking though.

I'm going to echo above and say I would forgo the time and effort to upgrade the unit with the '88 pigtail. Again not only is doing that cheaper overall, but will give you much better sending unit lifetime and readings.
