I was getting a bad petrol smell in my coupe over Christmas, couldn't find any external leaks in the lines either. Turned out to be a hairline crack in the tank right where the 3 pipe go in/out of the tank, located right under where you've put your relay. Every time I filled up the fuel was weeping down the side of the tank and into the car

Will check that out but im not getting any stink in the car only on start up really,
was thinking injector seals maybe?

Been replacing fuel lines this weekend, nothing like lying on your back sniffing vpower on a sunday afternoon
Got all the dodgy parts replaced but didint actually find any leaks so a bit confused to where the smell of fuel was coming from.

Today i thought i would fit the fuel pump relay mod as even if i get s new fuel pump it will benefit from having a better feed.

I started by removng fuel tank cover and carpets that were in the way.



checked out the wiring and had a wee peek under hatch to see what like the fuel pump change out will be.
I had a 30amp relay and some 1.5mm singles to switch the new relay from the old pump supply and used some hefty 4mm speaker cable for the new switched supply.
decided to leave all cables in original position to revert back if needed.



measured voltage across the pump at idle which was 13.4v
measured at battery 14.2v
Found a nice place to mount the relay (Red cube top corner) and soldered all conncetions on the relay tabs instead of crimps.
Used a cable gland shroud to cover the connections on the relay and bolted the relay to to a handy fixing.



Fitted my new pump negitive cable on the bolt of the relay and routed the 4mm supply cable through to the battery.
Still have to get a fuse holder sorted for the battery end so thought i would give it a quick check to make sure everything is ok......didint work
soon traced my error mixed up the polarity so my pump was sucking instead of pumping

final test 14volts at pump cant be bad

erm.. wasn't my big mate Donald was it? Black Evo, carbon bespoke body work, flat underside and the fastest saloon on the Scottish hills. Towed in by big 'the Vinyl Cut' van (pole dancer on the back doors)

...sounds like him.

It was a white Evo, just remember him using race fuel and a fuel tank like a 2ltr bottle of coke in the boot with a couple of fuel pumps
Got a wee vid of it somewhere.

cheers

Winner of the day was a evo 6 with 678hp

The torque curve behaves strangely at around 5200rpm, where it starts to climb again. Misfires or something?

If you look at post 91 you will see the RR results from another session on the same dyno/spec
Think she is only firing on four and the the RR Manny said it was running well lean so he had back off.
looking into a rough idle at the moment and one of my plugs is black after a run

New 3" downpipe has arrived from Prospeed

Very nice !!!

[sjw185]

Getting there Steve....fuel pump might be the answer to lean running ..fingers crossed

Yea going to sort the fuel lines and maybe relay the pump first.
Still chasing my ruff idle trying to remember where i left off.
changing pos channels tonight and going for a run

cheers
