So I have done some searching, and some asking, but still have a few points to clearify.

I have a set of Bosch 044 pumps, and a fuel cell(-10 lines) which fits in my original battery location. I have some Aeromotive filters(50 micron and 150) that I would like to use, but I really don't see many people filtering the fuel prior to the pump. Is it not a necessity? Or is after enough? I don't plan to fill my cell, as it is a track car only now. Thanks!

 

I filter mine before and after the pump

 

From what I have seen, that is more than most do. I was more wondering if it's a necessity, or just a precaution. I will be buying my fuel by the drum, and the cell is only 2gal. Are there any reasons race fuel will have more/less particles to filter out, thus negating the necessity of a pre pump filter?

 

Track car or not to be on the safe side why not pre filter your pumps? and I also filter right before the rail

 

My thought is: if I am only putting race fuel in it, do I really need a pretty filter?
My concern is: are there enough contaminants, in race fuel, that can ruin a pump/injector if in filtered fuel is used?

 

Filters are not necessary at all. Any car will run 100% fine without any fuel or air filters installed. You may even make more power without the air filter... So why run it? Because that's your engine insurance, right? It prevents anything from being sucked into the intake and potentially damaging the engine/turbo.

So why run a filter before your fuel pumps? Because it's your fuel pump insurance.

Why run a filter before your injectors? Injector insurance.

After you injest a loose strand of stainless seel braid, wreck your pump(s), and ruin your weekend - you'll no longer wonder, "why do I need fuel pump insurance?"

 

Don't get me wrong, I am learning every day, but by no means am I new to the scene. Thanks for the advise, but I am not too worried about "insurance" necessarily. More with,
"after pump filtering is enough for a race car, that sees only race fuel, filtered into the tank. But for a street car that just pumps it in, and goes, you will more than likely want one before and after the pumps".

Furthermore, from people who have done it with success in the situation. Thanks.

 

 

Just curious, why would filtering need to be any difference on a street car versus a track only car?

On a street car is there more of a chance of particles being in the fuel than on a race car?

 

That was my question, I guess. Are there more particles in pump gas versus individually barreled drums? There are arguments to be made in both, Im thinking. NO? I see many guys with no pre-filter on the 044 set-ups, and also some with. Why?

 

You'd have to ask all those guys why they are or aren't.

My guesses: (1) filters don't make power so it's the first place people skimp. (2) people think the internal 20 micron screen in 044's is adequate enough.

And if you subscribe to #2, keep in mind that your injectors have 7 micron inlet screens as well. So why not go filterless altogether?

The way it's supposed to work is so simple. Every step gets a finer strainer.

25 micron = pre pump
20 micron = strainer inside 044 (last line of pump defense, if you pick up dirt here, you lose flow)
10 micron = post-pump / pre-injector
7-8 micron = inlet screen of injector (last line of inj. defense, if you pick up dirt here, you lose flow)

And any particle smaller than 7-8 microns just flows right through everything.

 

There are just as many opportunities for the companies transporting the "race fuel" to contaminate it in their tanks or transfer to the pells etc. than any other type of fuel. Don't be fooled into thinking race gas is "pure". I filter heavy before pump, light after. If pumps fail it's bye bye motor. Also, everytime you open your fuel cell to put more fuel in, small particles of dust etc get in there as well as return fuel that gets recycled into the tank. Always a good idea to filter for protection.

Lots of guys bangin chicks without condums and not getting girls pregnant or not getting HIV. Safe right?

All the best man.
