Be a little more specific......... Do some looking around while you have the engine running and try and find where the smell is coming from

I didnt know they made a 283 for a 95 blazer

you got CPI? have you replaced it and nut kit?

also, do you 'top off' the tank when you fill up?

id bet money that ur cpi and/or nut kit is bad. can u tell wher the smell is coming from? mine had a strong gas smell in the intake and coming from the tail pipe. take off the IMTV, look for leaks and take a wif. if u can see clean areas or if there is a strong smell of gas in the monifold, the fuel regulator or nut kit is probably bad.

have you noticed a change in mpg ?

correction 4.3 liter.
it's hard to locate the soarce of smell,i can smell it at the rear of the truck and under the hood. this is my wifes car, but i drove it today , and the idle seems a little fast but it does drop back to normal sometimes. i don't know about milage as i don't drive it but maybe 3 times a year and she doesn't keep up w/ that sort of thing.

the longer u drive like that, the more damage is being done. tell her to start keep track of the mpg (miles gone on tank/gallons put in). if it winds up getting about 10mpg, strongly consider a cpi/nut kit replacement, which is like $300 in parts so i would suggest removing the upper manifold (takes all of 10min) to visually inspect the parts. if u see any clean areas, u probably have a leak. turn the key on to pressurize the system and u should be able to spot any leaks. hope this helps u.
