Spawn VII

anyways... i'm just wondering if any 2nd Gen RX-7 owners did a custom fuel filter? i'm thinking about moving the fuel filter from its original location (knowing how hard it is to reach by experience), and since i'm doing it, i might as well switch to a washable fuel filter (like K&N)... i saw someone with this on a 3rd Gen, but not a 2nd Gen... well have you guys done it? if so, which filter did you use??

hope i get some answers... *hint hint*

Ok you've got to have a TII cuz on the NAs the oil filter is sooooo damn easy to get to. Its fairly easy on the TIIs too as long as its not tightened super tight.

I retract my last statement. I thought you were talking about the oil filter. Now, I wonder what you see as being so difficult about the fuel filter though. It only takes a few minutes to change.

Dude, hell ya. That stock bastard is $30. Why can't we just plumb in anouther type of filter?

I can see it being a drag if you have to change the fuel filter every 3k but they usually last over 30k easily unless your tank is rusted out or gettin dirty gas.
You can relocate the fuel filter to the firewall, next to the brake booster or driver shock tower and just extend the rubber fuel hoses from the engine and tank side.

I run 2 aeromotive inline pumps, 100 micron ss mesh before the Eliminator pump, and 10 micron replaceable paper filter.
Each housing is around 85 bucks, but replacement of the paper fliter after that is much, MUCH cheaper.
I was just trying something new...

can you elaborate how you did that setup

i want to replace my fuel filter but i cant find it. It isnt in the gas tank is it? I have an 86 GXL.

scathcart

yep.
Sumped tank with 12 AN fitting leading to Aeromotive 12 AN ss filter, bolted directly to 1200 hp Eliminator pump, bolted directly to 10 AN filter, sent to 10 AN to twin 8 AN splitter, to fuel rails, to nitrous tap, to FPR, back to top of tank.
Filters are incased in red anodized aluminum housings, and the filters are removable.
All fuel lines are braided SS.

This setup is very expensive, especially on a car that is running a stock turbo and stock injectors, but I bought the system in lieu of the bigger and better things to come. I don't recommend it as a simple filter change, more of a complete fuel system.
As well, I wanted a pump and system that could supply enough fuel for my nitrous oxide setup.

Good lord man, you have enough fuel for a F-14 in burner

Yeah... I have PLENTY of Fuel... Now just think what would happen if I added a voltage stepper.... I could suppot 1500 hp easily.

Now all I need is a 1500 hp motor....

Ooogadaly googaly how many mpg do you get with that beast

scathcart

Fuel supply to the motor has nothing to do with mpg. Fuel is bled off by the FPR and then sent back to the tank. Only the fuel required by the motor is used.
The reason for such a big pump is when you are making a lot of horsepower, the engine will send less fuel back to them gas tank. When the engine is using enough fuel to lower the pressure in your lines, you run lean, and pop your motor.
I got such a big pump to use with my nitrous system, where plumbing of lines was an issue anyway, and so I wouldn't have to redo it all to support future modifications.

I get 450-500 km to a tank... so... 17-18.5 mpg. More is I lay out of boost and hop on the highway, less if I use the nitrous and go crazy left the right foot. My best is 22 mpg, driving like a bitch...
