Fuel Injectors 92 4R

SirJames · 08-19-2006, 10:07 AM

Lets have a Fire ?
OK so just for clairfication. If gas shoots out from arround the top of the fuel injector ( 92ish 4runner ) its that they (the injectors )are installed wrong and I have to remove all that crap off the top and realighn the fuel rails and injectors correctly ?
It would have nothing to do with presure is my question, can you have too much pressure to cause the gass to get past the oring in the injector? I tested it all when initally put togeather - the injectors move freely within the mounting rail...and still do. The seem too loose actually - could be crappy orings? these are new .

got a match ?

ok

Are you sure you tightened the fuel rail bolts back up? Also those washers under the fuel rail banjo bolts are suppost to be replaced any time you remove them.

Got good insurance?

It must be an assembly/O-ring issue.......you can't get enough pressure to leak like that

Yep had to disassemble it again - they said to put gas on the orings prior to insertion I did them dry -eek not good reassembled with new orings and added some lube- went in clean and no leaks this time.

thanks for the help
