the scissor tool for the fuel filter is not bad, just takes some getting used to, and you will want new orings for the fuel filters, its cheap insurance, I have seen numerous times, ripped o rings, then leak. Also put a dab of oil on the new orings before install, that way you dont rip them

RE: injector install and fuel filter
ok thanks guys, i went to pep boys today and they only had the scissor type tool for the fuel lines so i just bought that. I bought a purolator fuel filter, its the only ones they had. As for o-rings, i had to buy 8 boxes of o-rings and they come with 2 rings in them each. It doesnt have that little cap for the bottom of the injector, just the rings. Is replacing that cap important? or just changing the 2 rings on each injector?

yes but its better if u get new ones... if youre sure the old o rings are ok tho its fine.
u need the fuel line tool for both getting to the rails and getting to the fuel filter

Just take the 4 8mm bolts out of the fuel rails and pull the rails. The injectors will come out with it. The new ones should have orings already. The fuel filter tool you want to get is the pack of a bunch of disc looking things that are black, red, white, blue and light blue. Don't get the sissor looking thing its garbage.

RE: injector install and fuel filter
does it matter mixing pink top injectors with orange top? one of my pink top injectors was still flowing good and i changed my other 7 with orange top that i bought used from a guy on this forum. He told me his injectors had 20k miles on them and flowed good but i didnt have a chance to check, i guess ill see what kind of gas mileage ill get. His injectors looked kinda crapy from the outside, they must have been sitting for a while cuz they were kinda rusty. I hope this doesn't cause a problem?

You need to stop what your doing. 1. you can not mix injector sizes. 2. you can not just put different size injectors in without tuning the computer for them. Your car is going to run lean and blow up if you put smaller injectors in. The way the computer works is it tries to stay at 14.7:1 A/F ratio it does that by reading how much air is coming in thru the MAF(along with a few other sensors which I'm not going to get into) and decides what pulse width the injectors should spray. The pulse width for the 2 injectors will stay the same but the orange top injectors will spray less fuel then the pink wich will lean out the engine and BOOM.
