fuel filter location question

[shadango]

The fuel filter on my car was set up by someone to be in the line BEFORE the fuel pump.

To get her running thats where I installed the new one.

I know that the preference is to put it after the pump......before the carb.

What is the reasoning there?  Easier to push than pull?

I am reading 6.5-7 PSI pressure.

Thanks all.

First off, do you have an electric or mechanical fuel pump?

If mechanical, the only reason to have the filter before it, would be to stop it crap from getting in the valves of it. If you have a filter on your pick-up tube, I would just put your fuel filter between the pump and the carb like the rest of us.

Its a mechanical pump.

Just wanted to be sure that it wasn't causing a problem......

As it stands, I dont have any room left in the rubber line between the metal line and the carb.....I am installing a regulator now and space will pretty much be gone what with that and the pressure gauge.....I would have to shorten the metal line.......would prefer not to if the way I have it isnt an issue....

i run a filter pump before fuel pump,,,,,,

Whats a filter pump?

I have a filter before the pump too.  Didn't want to mess up that expensive vapor seperator...

I let the screen in the fuel tank do the work & place the inline filter between the pump & carb

Does this filter go between the pump and the carb: http://www.shopatron.com/products/productdetail/SS+Series+100-Micron+Fuel+Filter/part_number=12316/415.0.1.1.337.0.0.0.0?pp=48&sort_selection=price_low_high&

The factory put the filter between tthe pump and the carb.  The screen in the tank is enough to filter the large stuff out so it doesn't get in the pump.  The main filter is to catch the smaller particles so they don't get inside the carb.  You want the filter after the pump incase the pump deteriorates inside and starts losing small pieces of itself.

Your running a 318 aren't you?  I think 318's have always had the filter right after the pump located under the alternator.  The filter location changed on 340's. Some I've seen were located higher up ontop of the intake manifold and used a 2 piece fuel line.

the suction side of the pump is the weak link , you are far more likely to get stranded with a mildly dirty filter before the pump & trying to pull fuel through it , the filter is designed to have fuel pushed through

Why are you installing a fuel pressure regulator? Is your fuel pump a stock replacement or something much higher volume?

Typically, you don't need a regulator unless you've gone electric or really high flow mechanical, which would seem out of sorts with your combination.

It is a 360ci where the 318 used to be.  I'm replacing everything under the hood with a Carter mechanical fuel pump.  But had intended to install electric later.  I was thinking to install the fuel pressure regulator, gauge and filter at the same time, to get them out of the way.  Will this create a problem? backasswards approach?

When replacing the rest of the fuel system, do I need to adjust any of the my purchases [up] from the stock hardware because of the higher cubic inches?

unless you are going to a 408 stroker or the fuel system is in bad condition the rst of the fuel system should be fine as is
