A couple of years ago I bought two of these filters.They are about 4 inches long and basically a glass tube with pretty chrome hex ends and hose fittings.Inside there are two rubber "O" rings that form a seal between the glass and fittings.They failed.The filter in the '36 was drawing air bubbles (filter before the pump). The filter on my '49 C****PU was squirting gas everywhere (filter after the pump).I tightened them up and stopped the leaks.A temporary fix at best.
Are there "O" rings out there that can stand up to today's gas?
BTW.... If any of you guys have one of these filters on your old Ford,you might want to check them out.They could leave you stranded and/or cause a fire.
 
I have found that if those glass tubes have sharp edges where they were cut to length, the sharp edges will literally cut into the O-RINGS causing a leak. Be sure and buy the filters that have the edges smoothed off like you did using a Bunsen burner in chemistry class. Also, use a drop of lube on the O RINGS and don't over tighten. Ace Hardware has a good selection of O-RINGS. I see where some of the newer filters are using "squared off edges" O-RINGS. Been using the same filters for past 10 years. Change O-Rings once a year to be on the safe side. One between tank and electric fuel pump and another in front of the carb. There was a thread about these type filters a few weeks ago warning about hazardous fires due to leaks.

I use these same fuel filters on my car. I've changed it many times and they have never failed.

The one I have is just before my electric fuel pump. I was little concerned that a rock my fly up and break the glass. To avoid this, I cut a piece of clear rubber tube and place it over the glass tube.

I also keep a spare in the trunk. Hopefully it will always remain there unused.
 
I just took one apart.The O rings/washers look as good as new.I'm sure I tightened them good enough when I installed them. Strange they would both start leaking at the same time after two years.Sorry Mr. Gasket.My fault. I apologize.
 
I have one on my 50 and it started leaking. I mean a serious leak. When I checked it, one of the ends was loose. They screw on so I thought I would just tighten it back up. Worked for now but, after reading comments from others, I'm going to change it for a solid metal filter. I had an engine fire many years ago and I can't afford another one.

Yes, nitrile o-rings can be had at hydraulic cylinder rebuild shops.
