--TECH-- USE A TRUSTED SOURCE FOR FUEL

Hey guys,

I know most of us use a quality gas station and one that you visit on a regular basis. Some of us however do not, and for those that visit the 'race fuel' pumps at the track please take note of the following.

This was removed from a 2009 Z06 track car. Customer uses a blend of street and track fuel but also picks up the fuel at the track. On the dyno with it and it was going lean, fuel pressure check showed an increasing drop in fuel pressure through the run to the point it was dropping below 40 psi at the engine. As you probably already know the filter is mounted inside the fuel tank, so replacement of this is not an easy task. While what I am showing you is off a Z06, your new Camaro's use a very similar setup with the filter inside the tank such as this.


FUEL PUMP ASSEMBLY



FUEL PICK UP



FUEL FILTER





For those of you that buy fuel at a race track that might not see much action or turn over on the fuel, I would suggest filtering the fuel before you pour it into the car.

I do not think you would find this from any quality normal street station that has a high turn over and constant fresh fuel in the tanks.

Be sure to use a trusted source for your fuel!

i always go to a place i like that has tons of ppl getting gas all day. fresh fuel .if they are truck putting fuel in the tanks i go to a diff place as it usally stirs up the dirt at the bottom. i do get gas alot in cans and stuff and i always look at the bottom of the can to see if dirt is in their after filling them. its a good way to see what in the tanks. great write up . and that is some nasty fuel .

This car only has 6400 miles on it, so it isn't a high mileage car either.

I get my 94 Sunoco at 2 busy stations and never use race fuel in either of my cars.

wow at 6400 miles . i figured way more just looking. he poured 5 gallons of race fuel in and 1 gallon dirt. a buddy told me to get a gas can so when i do run race fuel u can look at it and see what settled . because alot of ppl sell it and at the end of the year let it set till next year or use the same barrels over and over. makes sense after seeing this.

I don't want to say this was just track fuel per say that did this.....but at any rate he grabbed some fuel from an untrusted or old source at one point or another.

I don't get that they switch the filter being outside the pump so people can change them

I think they combined the filter, and return/regulator system to being inside the tank to reduce in vapor leaks and build up of heat in the fuel as it doesn't have to travel all the way to the engine and back in a traditional style return system. Why they can not have a simple external filter though...no clue.
