Fuel Filter

MMNineInchNails · #1 (**permalink**) 08-13-03, 02:24 AM

Sorry about the repeat. I accidently posted this in the electrical section. I was looking for my fuel filter and cant find it. Is it built into the side of the carb?

If it's a Q-Jet carb, it's right in the front of the carb where the fuel line attaches.
Here's a picture. The circle is around the filter housing.

That's where i thought it was if it weren't hidden somewhere else. Damn fuel lines in the way so i can't get open that part. I'll have to take off the carb or something.

1" line wrench on the filter housing, and a 5/8" line wrench on the fuel line breaks it loose. Then pull fuel line out of the way (it's tight but it CAN be done) and unscrew the filter housing. Be careful not to lose the spring behind the filter or (and this is IMPORTANT) the thin plastic seal that goes around the end of the filter housing (this is the only actual seal for the housing). The seal "clicks" in place on the end of the housing.
IMPORTANT TIP: DO NOT USE TEFLON TAPE ON ANY OF THE THREADS. (line or housing)

Is it bad if there is no spring in there? What will it do with no spring? I pulled it off and there was no spring inside.

BS!
The Q-Jet is great when you know how to set it up.
And YES, it DOES matter about the spring missing. That's what keeps the filter seated against the housing. Without the spring, you get no filtering.

Looks like I'm going for the universal one seen in the link below. I'm not going to waste any money on a new filter if it wont work.

Not sure what you meant by universal one but you COULD just install an inline one and it would actually do a better job.

Anyone know the cfm output of a q-jet off the top of your head? Just curious.

I don't know if you CHECKED your link but it only takes you to the Parts America home page.

There were different size Q-jets.

Just wanted to add to that post about the Q-Jet airflow ratings. I had to wait until I got to work to look up the exact sizes.

There are 2:
1-3/32" venturi (primary) = 750cfm
1-7/32" Venturi (primary) = 800cfm
As I recall, your car has the larger one but a simple measurment can nail it down for you.
