This DIY is to be preformed with a very high level of safety. you are dealing with fuel. DO NOT preform this in any area where open spark or flame is present. wear SAFETY EQUIP such as masks (to prevent from inhaling fumes), gloves (because you will get fuel on you), and eye protection. Before doing this DIY you should have not driven your cb7 for at least 3 hours as a safety precaution. I am also not responsible if you fuck up anything on your car. preform this DIY if you feel that you are competent and skilled enough to preform this.
1st off lets look at the tools that we will use
Prep work.
remove gas cap to release any pressure that may still be present and replace immediately afterward.
have the caps on the last thread so they will be easy to remove because initially they are on there good. and when you remove your old filter, fuel will go everywhere slowly and you will want to throw it on asap. (in the pict is my old filter so thats y it looks all junky)
ok now that all of the prep work is taken care of now we can tackle the beast.
zoom
ok so here is the area and objects we are concerned with.
go ahead and remove your intake which should take about 2 minutes. If you have a stock air box you know the drill.
next are these lil 10mm bolts. the one closest to the passenger fender is a beech to get to and you might possibly drop your bolt. just try your best. (it also helps to put rags underneath the box so if you do drop the bolt then it will catch it. you are going to have to put the rags under your filter n e wais so you might as well do it ahead of time to prevent some headache.)
ok after you remove both of the bolts just move the box off to the side or top or something so that you can access the 3 bolts in the next picture. it is not necessary to remove the box and its actually more of a pain than what its worth cause its really not int he way.
start by placing rags all underneath the filter. be very generous because it will soak through one layer very quickly.
next begin by removing the 17mm bolt. this one was a beast on my car and i had to use a cheater pipe. be careful to not use all of your body weight and pry it off cause its held on by flimsy bolts attached to the firewall. I pushed on the ratchet and pulled on the whole filter itself. Be patient this bolt is the hardest to remove (at least on my car)
next move on to the 14mm bolt. this bolt required a wrench to tackle. preferably a flare wrench to initially loosen and finally tighten it. you may use a normal wrench in between these processes. this is to protect the bolt so you dont strip the shit out of it.
once you take this 14mm bolt of. fuel will begin to slowly drip. DO NOT BE ALARMED. you didnt break anything. it will continue to drip until you put this bolt back on the other filter.
quickly remove the 10mm bolt which holds the entire filter on.
lift the filter while moving the 14mm out of your way.
quickly set the new filter in place and begin threading the 14mm with your fingers. you will see that the hole where the 17mm bolt came out of is beginning to fill. this is normal. after you start the 14mm replace the 10mm bolt as to secure the filter. finish up the 14mm and tighten appropriately.
Last up is the 17mm again but BEFORE you put it back on make sure you replace the 2 metal rings that should have come with the fuel filter. Retighten the beastly 17mm bolt. Replace the vacuume box and be sure to remove the gas tainted rags (all of them).
replace intake and your done.
I would suggest letting your car sit for a few hours as to let the remaining gas that has spilled evaporate. (maybe its just me cause im so paranoid)
you may reopen you gas cap to check for pressure. i actually had alot when i reopened it. so all is well
This is my contribution to cb7tuner.com. hope this helps some people. This should be replace at LEAST once every 2 years. Im sure it will help you with MPG. feel free to email me with any corrections or comments that you feel are important to edit this post. thanks.
