View Full Version : Fuel filter Before or AFTER pump?
EC's 327 Dec 29th, 06, 05:02 PM I just bit teh bullit...I bought a new fuel tank, and after droping it...yeah the fuel lines are JUNK
So I went to Jegs today and bought all new lhrd line and braided hose and AN fittings (which add up quick btw!)
So my question is....I want to run a fuel filter....and a mechanical pump. Can I put the fuel filter between the pump and the tank? Ie suck thru? or should I have the pump push thru? The Heater core hose is kinda in the way and I could use the realestate.....

wiskeesour Dec 29th, 06, 05:27 PM filter should be between tank and trunk. keeps trash out of pump and along the length of the fuel line to the pump.
Dont they make an in-tank filter now?
sc68z28 Dec 29th, 06, 08:56 PM I use 2 filters. One 100 micron in the tank before the pump. Second 10 micron after the pump.
You say a new tank, stock type? If you are using a stock type pick up with a sock on it (a screen prefilter), then just use one after the pump.
And it does add up Quick, from tank to injectors I spent over $3k. ---Bill.

I could see that! Now it loks like my fuel system will be ALL new...the fuel pump I have is not gonna plumb the way I wan so I am going to get a new one...and I need some differnt fittings, a new pickup, a new filter, and I may bypas the heater hose to make it look cleaner...
My big decision now is weather to hard pipe up to near the carb (deamon dual inlet) then braided hose, or go braided all the way from the pump.
and how to fit in a guage, and a filter without makeing it look unkempt

BlackoutSteve Dec 30th, 06, 02:41 AM The pick-up in the tank should have a screen to stop most junk getting sucked up. Anything small that gets passed this "gauze" won't bother any pump.
And it's always best to have the in-line filter on the pressure side of the pump, which is what the factory did.
Filters create a restriction which when on the vacuum side, can help give you vapor lock.
67FamilyFun Dec 30th, 06, 07:53 AM I would offer that the in-tank pick-up is made of some nylon-type fabric and deteriorates over 38 years or so. I recently removed my pick-up and the stitching that held the thing together was gone...
That filter is sufficent for the tank side of the pump, but I'd be cautious about making any assumptions regarding it's effectiveness if it's original equipment...

EC's 327 Dec 30th, 06, 08:42 AM It will be new. ALL will be from the tank to the carbs now....
The old stuff is just in to bad of shape for my comfort...
I kinda have a theory...If the part is off the car...or close to being off, and its questionable and has to do with safety, I just replace it.
The main goal is to have it all braided hose or hard line...NO rubber hose. I just dont trust it.
I thought if an idea for clearing the heater hose, a Tee with a port for the gauge, then I can dump one coupling, But i cant find a Tee thats not in a kit...Alls I need it the Tee, Nothing else.
You think it would hurt the T if I drilled and tapped the side for a gauge port?
and Thanks Everybody! You have been TONS of help!

Agreed.
I run an Earls -6 inline filter just before the carb. There are pics on my website. This in addition to the in-carb filters.
EC's 327 Jan 3rd, 07, 06:16 PM Will the 69 3/8 fuel pick up/sending unit with a return line work in a 68 thank? I am thinking that if I am going to buy one...I may as well get the one with a return incase I need it later with upgrades....
Or am I stuck with a 68-69 returnless pickup?
Thanks!
