92 xj 4.0L
mr. haynes says the injector o-ring kit comes with 7 o-rings and 6 seals (extra o-ring for the regulator) one is color coded brown and the other black. went to DC and they only had kits of 2 o-rings of the same color for 9-10 dollars per 2! went to Salvo auot parts and they had jeep 4.0L MPI injector kits for 16 bucks. it has 13 thick black o-rings, 5 thin black o-rings, 7 white plastic spacers and a throttle body gasket and one larger thin o-ring. all have what looks to be the same I.D. except for the one larger thin o-ring.
1) anybody know exactly what I will need to replace injector 0-rings?
i thought I would need 13 o-rings total, 2 per injector plus one for the pressure regulator. Haynes says each injector needs an o-ring and a seal which is made of a different compound than the o-ring
2) extra stuff in this kit to replace fuel line fittings without using the quick connect replacement?
4) is the larger o-ring for the TPS/IAC?
thanks for any help
