Upgrade For Fuel Pump (KLZE)

Nd4SpdSe · Post by **Nd4SpdSe** » March 28th, 2005, 9:42 am

I remember talking to someone a while back about my KLZE swap, and that person asked me if I upgraded my fuel, pump. Now, I don't remember the specifics on why I should have done it, since it's not really mentioned by anyone who's done a KLZE swap, but it can't be a bad thing.

Now, I need to replace my gas tank (the new one should have arrived today) and I was thinking if I should replace the fuel pump at the same time, and fuel filter, since I've replaced neither since I've bought the car. I originally though that the fuel pump was located in the gas tank, making it hard to get to, but with some research it seems like there is access to it from under the rear seats.
It seems that the Walbro 255 is a common choise, my guess I would get the one designed for an Mx-6?

yeah get the 255lph walbro pump, the pump i think can be pulled right out from under the rear seat, you should buy the new pump according to the tank that it is going into, so buy it for the mx3.

go to http://www.autoperformanceengineering.com , then click applications under fuel pumps, go down till you see the mx3 in the list. the 255lph pump is 94 bucks.

Do i need anything else (like a fuel presure regulator) or is it just install-and-go?

Not to jack your thread Mike, but you're changing your fuel pump because of the new fuel tank I'm assuming. That makes me think of what the life span or expantancy of the original fuel pump should be. Should I at some point in time change mine as a preventative maintainance thing or change because of the ZE and IM mod or just wait til it gives out. Don't like the latter though.

I'm just changing it as a preventative maintenance for a 13yr old fuel pump that's at old as my rusting gas tank, supplying fuel to a bigger engine. New tank, might as well get a new pump, and since my old tank is rusting, I'm sure the pump has picked up the shite that's floating around inthe tank. With a new filler tube that went in last year, and new stainless fuel lines going in, might as well complete the package.

Outstanding, I love your perspective and preventative/precautionary measures, just good old sound judgement.

Hey, I love my Mx-3, and plan on keeping her for a long time, so it's only necessary; a maintainted car is a happy car

. Plus, I tend to have "high-demands" for my car, so keeping the car as mechanically sound as possible allows me to enjoy it to it's fullest, while keeping it reliable and functional. And one more posivite is that I'm not exactly "mechanically-inclined", especially this being my first car, so stuff like this really helps in the learning process. And another thing, might as well be doing it while I have the cash, things always like to break down at the worse times

i swapped mine out for a walbro 190 and it works well, i noticed a steadier power curve as compared with the stocker that was 12yrs old and 140k miles beaten. when u order the pump get teh one for a 93 mx-6/pgt it fits fine

Mikey, which one did you end up getting? The FPM 005 or FPM 006?
Was it one of these?

Did it look like one of these at the end?

Left pump is like 516, GSS242, GSS307, and GSS340
Middle pump is like GSS250, F20000141, GSS317, and GSS342
Right pump is like GSS278, GSS315, and GSS341
or

The new F20000169 fuel pump

Did you need this kit also?

The TCA 380
The TCA380 kit is specified for the following vehicles:
'92-'95 Mazda 323 1.6L
'92-'95 Mazda MX3 1.6L & 1.8L

Or did you not need or use any kit at all

There's no reason to upgrade for an N/A KL install at all, unless you just like to spend money for no reason. And even if you went to a turbo application, the 190 is PLENTY for up to 300+ HP. A 255 is just going to make more noise.

I always tell everyone, you WILL notice a difference when changing the fuel pump on a N/A car. I noticed on both my MX-6 and MX-3 the car seemed to react better when open her up.

And as everyone else said just get one for a Probe/Mx-6
