Basic Fuel question

sprintgtvgus · Post by **sprintgtvgus** » Mon Jun 22, 15 8:26 am

On my 440, should the fuel filter look full? It is a new one but appears to be only half full.

Just speculation as I have had the car cut-out a few times, sometimes on hills.

I do have a new fuel pump if needed (manual)

This Thursday I'm going for rolling road set-up and to measure afr etc, not sure that the carb or the timing is correct really.

Yes should only be half full

if i was you i would forget the rolling road and spend your money at Antons garage

Buy an AF set up and then you can se how it performs in real life situations.
Mine has been a great asset. Just tuning the carb for idle was straightforward as was swapping out jets etc and checking the different AF readings.
£150 and you have it there all the time as opposed to a one off rolling road tune. You might want to change things down the line ie fitting a 3/4" spacer leaned my car out nicely and the AF gauge showed that.

Thanks, good to know.

I am going to stick with the dyno now as they are going to set the timing and fuelling (I have a box of jets and springs) and they seemed to do a good job with my alfa.

Measuring the AFR under load and seeing what get's best power isn't a bad thing.

I don't have an exhaust lambda port yet, and frustratingly I sold an innovate wideband a year or so ago as I thought I wouldn't need it....!

If you can see the fuel in the fuel filter change it for one that's not made of glass or plastic.

How come glass or plastic filters are no good?

Significant fire risk, especially in crash. But great for seeing if you have fuel. Wish there was a safe way to achieve that, I looked a while back but didn't find anything practical (not much point right now

)

If they are anything like the ones made for Harleys they always leak.

Yes either type can crack and leak, not good. I've had a fuel fire and it ain't funny.
