I smell gas and I don't know why ???
 

Okay so I have yet another new problem with the truck after I get done driving and I get out of the car I smell fuel, very strong smell not faint I know that the fuel line was cut and rigged by the previous owner and I am running a fuel filter that isn't meant to be used on my particular vehicle (it is cut and rigged right in front of the fuel filter) maybe about 5 inches in front of it anyways I also have some delay when starting my vehicle after it has sat for an hour or so it does start just takes it about 4-5 secs as opposed to when I get out for maybe 5 mins then come back and start it again it starts right up so I am not sure if that is related to the smell of fuel and the delay of starting after it has sat for a while. I am just curious how much do fuel lines cost and are they difficult to do or is it best to have a professional do it?

need more info is it cpi or tbi if its cpi do a leak down test or just pull the upper half of the intake off and look for fuel washing

I think it is cpi ... not even sure how to find out what it is but it is carburated so I am assuming it is cpi what is a leak down test? just look and see where fluid is leaking down from? sorry Im not more mechanically inclined

Are you talking about your '89?

In that case, it's TBI (you don't have a carb or CPI).

okay like I said I am not very mechanically inclined unless it is an oil change or minor stuff so there you have it serras it is tbi ... another question completely off topic but I figured better not to start another thread what is the stock tire size on my blazer? and also what is the biggest size tire I can fit at stock height I thought maybe I can squeeze some 30's in just a thought ...

you might be able to pull of 30's but there will be serious rubbing,might as well do a 3' body lift to get those suckers under there.

30's will work as i had some on my 91. you might have to crank the bars up a inch or so as mine was already up a inch before i put em on.

stock tire size is 235/75r15
should be on the sticker inside the drivers door jamb too

Instead of worrying about what tires you can fit on there... get that fuel problem fixed. necessities over accessories.

You dont have a carb on a 1989 and you dont have CPI either. CPI came out in late 92, you have TBI. Have you pulled the dip stick to see if their is gas in the bottom end?
