The pintle caps have no effect on performance. Their sole function is to keep the injector lower O ring from sliding off the injector and falling into the intake port. If the correct pintle caps are used, they do not have any effect on the injector spray pattern.
Fuel injector seal kits with 2 O rings and a pintle cap (Borg-Warner P/N 274081) are available at Pep Boys auto parts. Cost is about $2.74 per kit.. The following are listed at the Borg-Warner site ( http://www.borg-warner.com ) as being resellers of Borg-Warner parts:
http://www.partsplus.com/ or http://www.autovalue.com/ or http://www.pepboys.com/ or http://www.federatedautoparts.com/
Most of the links above have store locators for find a store in your area.
Use motor oil on the O rings when you re-assemble them & everything will slide into place. The gasoline will wash away any excess oil that gets in the wrong places and it will burn up in the combustion chamber.
The pintle caps fit either injectors with a pin sticking out the injector end or 4 with more tiny holes in the injector end
Heating the pintle caps in boiling water makes it much easier to install them.
