So I woke up today thinking I was going to replace the fuel filter on my '95 SC400. WRONG!

I've used almost an entire can of PB Blaster, wrench, even a pair of Vise Grips and a hammer....all to no avail. Those damn nuts are SEIZED!

Any suggestions that don't include cutting/breaking/replacing the hard lines?

Try using a piece of pipe over the end of the wrench/vise grips for extra leverage.

Go pick yourself up some flare wrenchs. They work great on brake and fuel lines as long as you havn't stripped the nut.

You guys are giving excellent advice, I had the same prob. The only way I got through it was a pair of vise grips and a line wrench, and yes the gas continues to run down your arm until your done, sweet.

True Story!

eeyeah... the fuel filter placement on the SC is by far the dumbest thing I have ever seen. Well, I take that back... My 4Runner had the fuel filter in close to the same spot, and it was a b**** too.

I ended up taking my SC to a mechanic to have it done, turns out the rear line needed to be replaced... Cost a little over $200 for the whole deal.

I used to be a Subaru fanatic, and most of their cars have the fuel filter right in the engine compartment. Takes like 5 minutes to replace. If there's one thing Subaru did right, it's that. How f-ing hard could it be to place the filter in a better location?

Anyway, /rant.

yyyyyeeeeeaaaaaahhhhhhh.........so I bought an assortment of flare nut wrenches...now both nuts are rounded off (yes, I used to correct size - 14mm).

I'm thinking about cutting the hard lines a few inches from the filter in each direction, getting short straight hard lines to put in the new filter and run high-grade rubber hose to connect the new and old hard lines.

Anyone think this is a bad idea?

Well you can forget that...no local parts stores have flare nuts and fuel lines in metric sizes

thats how my fuel filter was when i got my sc 400 .no not even .the guy who had it before did not even have one on the car .so i jus chopped the rubber hose he used and added a filter .works perfect to me

Found what I need at Oreillys and Pep Boys...bought two adapters into the fuel filter, two flare nuts+hard line, tube cutter, tubing flare kit, o rings, teflon tape, fuel injection hose, and clamps. Total bill was about $51 (ouch!) but worth it if it works!

Guys....I just had an epiphany...instead of going through all this trouble and spending $70 (in my case)....wouldn't it be just as good to use, say a 300ZX fuel filter (just like the OEM Toyota without the bracketry, but only like $10), cut+flare the factory hard lines, connect with fuel injection hose, and use some sort of cheap clamp to hold the filter to the body??????

Hrmmmmm.......

yes...that is a great idea. people do this all the time to add a second fuel pump in their original fuel line. make sure you flare the ends of the fuel line though and definately use fuel injection hose like you said. I would also recommend double clamping the fuel hose on the line.

^ Great, I knew I wasn't that stupid, lol! I tallied up my costs and I'm just going to go the route I've begun, but to someone who hasn't spent anything yet, DOOO EEEEEEEET!

'91-'96 (?) Nissan 300ZX Twin Turbo fuel filter $9-17 depending on brand. 5/16" or 3/8" fuel injection hose, 1'-2'. Clamps, flaring kit, tube cutter, and some sort of bracket to attach the filter to the chassis.

All done! Definitelly made an improvement - much quicker! I even have the speeding ticket to prove it! :P

You've never seen the filter placement on a 3rd gen RX-7 then, if you think the SC is bad. On the RX, they put the fuel filter ABOVE the rear differential. Its a total PITA to take that out. At least its easy to get to the SC's filter.
