fuel presure gauge

[speedfreak]

Hi team,

Looking at putting a analog fuel presure gauge in the rally car but cant really find a kit that id be happy to put in.

Anyone installed a guage like this/know where i can get one?

Hook up a sensor to the ecu?

You shouldn't be worrying about gauges when your rallying anyway. Safer to leave that to the electrickery wizards in the ecu imo.

Chat to Tony at RDL perforamance in Hornby, he has almost finished the setup on my track car..Should have it running before Koom

haha yeah thats why its going in front of the ballast seat, err sorry co-driver

i would hook it to the ECU however i run a possum link so dont think i have any extra inputs or anything

do you know what you ran into the cab at all?

What sort of gauges have you looked at?

I reckon an a/f ratio gauge would be more useful (as an "oh look, the #*&&$ has hit the fan already) if you want something for the left seat driver to entertain themselves with. Something like the ngk or innovate gauges?

Im having issues with the car cutting out intermittently so im trying to use it for fault finding, see if the pressure is dropping causing the car to cut out, or if the car cuts but i still have pressure i can look else-ware. i have a laptop coming to hookup to the possum-link during runs to log what is going on to see if i can see a sensor or something that is dieing, but need to know if fuel pressure is there to start with

Good old fuel surge?

I used to have an odd issue with the Possumlink at trackdays, where it would go into a "safe mode" after half a lap then come right after another or two. Never figured that one out.

But if your using a factory fuel tank and pickup for the pump (and no surge tank), it's good old fuel surge. Mine would surge even with over half a tank of fuel.

has surge tank usually, feels very much like fuel surge, but was happening with the tank, without the tank etc. ive replaced lift pump to make sure the pump sure tank is getting enough fuel, but this is why i want the guage, so i can see the pressure drop to confirm or if its cutting with no pressure drop then its something else....

this fault was very strange, does seem to be load related as went the whole way up ashley forest no drama on the last run, but then cut out after the dipper and after the finish.

im rewiring for dedicated feeds for the in tank and external pumps, i have a laptop to log all the stuff off the ECU to see if i can see an error with any sensors like a dodgy TPS or something, so the only thing i cant see is the fuel presure. im hoping the new lift pump and wiring will solve
