FFredo - WHERE are you man? What's going in with your truck? Been watching awhile to see if you've gotten her back up and running.

Enquiring minds (not to mention nosy busy bodies!) want to know.

I know I'm late, but
I'm really sorry to hear that Fredo.
I also thought of the first one.
So does that mean (the first one) that original glass fuel filter that is Oh so cool is still safe to use?
I haven't heard anything bad about it, and it's the one I want to run.

[VWNate1]

Yes .

[Rufton]

I was lucky that my glass fuel filter w/ those cheapo plastic nipples took a leak when I was working under hood. Scared the crap out of me. I promptly replaced it.

[Dan in Pasadena]

Yada, yada, yada.....where's Fredo?

Sounds like "Where in the World is Carmen San Diego?"

[mechanixman]

So this is alright?
Up and away from the manifolds, and away from vibration

Yes , close ~

It should be as close to the carby as possible to prevent it from vibrating .

Use a short bit of hose , only the least amount possible .

Those " Take Apart " things are not really good ~ they tend to leak .

FWIW , I see you're getting a lot of seriously BAD ADVICE here from folks who clearly know nothing of what they speak .

You cannot get a gas fire by spilling raw gasoline onto the exhaust manifold failure to understand this means you weren't paying attention in 7th grade science class .

I see you still have a 216 C.I.D. BOWTIE Babbit Pounder ~ this is great , just remember to never run it on the freeway else you'll kill it in short order .

These sturdy , 1930's tech engines also like the thinnest oils you can find , 10W~ whatever , and use a fairly good bit of it leaked & burned , by design .

Why can't you just put the filter in the line half way between the tank and carb?
What's the differance compared to being at the carb?

I think the idea is don't use the glass filters at all.
They're subject to breakage. Hence, FIIIRE!

Ha ha I got the idea.
But my plan is to use this (i already had it) until I know for sure my fuel system is good and ready to go. THEN I'll run straight over to Oreillys and get the metal canister

Old thread but those pieces of junk have been listed as the cause of of a great number of engine fires on the net and elsewhere A lot of guys run them because they think they are cool looking and just as many be cause they think they like to see the fuel go through them. Others think they will be able to change the cartridge.

[Dan in Pasadena]

Your truck, your decision but it's DIRECTLY over the top of your exhaust manifold in the photo. Heat + gasoline? Uh....no thanks.

[mechanixman]

Ha ha yeah I got it.

[mknittle]

Those things are lick a hand grenade. every time you start the truck you pull the pin out a little bit farther.
If you like the replicable filter Jegs and Summit sell anodized aluminum ones.

[mechanixman]

There are 2 filters you're suppose to use; pre pump filters, and post pump filters.
We're talking about the post pump filters, or the filter that goes between the pump and the carb.

When I pulled glass filter I replaced w/ a larger pre pump filter and it works great. Now that you mention it, If the rubber breaks down after a decade or so debris could get into carb. Don't think I'll bother but it would be nice to have an additional last chance filter attached to carb.

"FWIW , I see you're getting a lot of seriously BAD ADVICE here from folks who clearly know nothing of what they speak .

Coconut-kid, I think your comment was a little bit condescending, and not correct either. Do you know what happens to gas when it is spilled on a hot surface? It becomes vapor which is highly flammable, even explosive. A spark from the alternator brushes or any other source will set it off. To say you can't get a gas fire by spilling gas on the exhaust manifold is wrong.

You might ask FFredo if a gas leak will cause a fire or not in case you didn't read the beginning of this thread.

'Ya think? I caught the patronizing, "...you're a bunch of dummies and I know better" attitude. But then I've written things I later thought better of myself so I didn't want to blast him. (Of course now that YOU brought it up, I apparently have no problem "dog-piling" on top, )

Anyway, speaking strictly for myself - why even take the chance? Why rely on your 7th grade science lesson (Coconut KID) to save your hard work and dollars spent? Just change the damn thing out and quite making everything a pi$$ing contest! ...Or don't and do not post when your friggin truck burns expecting sympathy.

Yes, big fire risk.

The hot manifold plus gasoline can cause the fire w/o any other spark because autoignition point of gasoline is roughly 500F.

[Coconut-kid]

Wow. Ok maybe I'm missing something. I was just trying to ask why the filter needed to be by the carb. Ill need to go back and read over everything.

@ russell ashley: The first part of my post was a quote from someone else.

Sorry for any misunderstanding.

I really wasn't trying to make a pi$$ing contest ~

I'm a Journeyman Mechanic and I take the job *very* seriously ~ I get to fix lots and lots of really weird problems that were caused by bad advice .

My GM Factory training and others , made a point if spraying gasoline of red hot (glowing red hot) exhaust manifolds whilst the engine was running to prove this point . the flash point of gasoline isn't 500° F .

Fuel filters are never supposed to be placed before the fuel pump , only after .

Some cheapo current aftermarket pump manufacturers have added B.S. instructions to add a pre pump filter , it's still wrong .

In the end , my advice is free , so it's no doubt worthless .

I had never heard this. I have been running filters between the tank and fuel pumps since getting a bad tank of gas in the 70's that caused a ton of residual problems.

Was it James Bond who said "Never say never?" Just funnin ya.

BTW........
Toyota ran the FF back on the frame rail near the tank for many years on carb'd PU trucks. Worked great.

That may fly on engines with fuel injection that I suspect you have had your GM training on for the past 25 years. That is most likely on late model FI units as I doubt GM has taught anything on Carburetors since 1990 when the last Carburetor ed 307 's rolled out of the factory.

I've put a filter in the line between the tank and pump on every car and truck I have put together since 1981 when on a road trip my fuel pump went out because I had left my gas cap on the fuel pump at the Grand Teton National park gas station. Ten miles east of Whitehall Montana my fuel pump failed because I had picked up fine gravel/course sand from driving on fresh gravel from road construction for who knows how many miles. I got it working good enough to get the truck over the hump and coasted downhill with the engine off and made it into a gas station in Whithall were a kid who was going in the Navy the next week sold me the pump he had saved back for his 55 chevy for 20.00 helped me put it on. We put a filter in front of the pump when we put the pump on and I made it on home. On my 71 I've plugged up who knows how many filters between the tank and pump because I had a tank with a lot of crud in it for a lot of miles and I got pretty good at changing filters on the side of the road. Those square body 76/80 Cad Sevilles have a nice filter setup up in front of the tank near the left rear wheel if a guy finds one in a wrecking yard The cover unscrews and you replace the filter and gasket and go again. It' the same Fram CG20 style filter that Cad used for years in the 70's.


On the sediment bowl/water separator that all too many guys think is the holy grail of traditional hot rod filters that they have fastened to their carbs. They aren't much of a filter but are used on a lot of farm equipment gas and diesel as a water trap/sediment bowl to catch the water in the fuel and catch the big chunks before the fuel actually goes through the fuel filter. New gaskets are readily available and you can find the glass bowls at farm equipment dealers parts counters.
