fuel filter micron rating? Is it better to have a higher micron rating on the fuel filter? I am going to be replacing the stock fuel filter and have seen several filters with rating ranging from 10-100 microns. This is going into a pump gas car but will need to be able to flow enough for 800rwhp. Any ideas?
The higher the number the larger the particles it will allow to pass. Also the higher the number the less restrictive its going to be.
To handle HP you need to look at lb/hr or gal/hr ratings...
Multiply injector lb/hr rating by 8 = total lb/hr the filter should flow. If the filter is rated in gallons per hour, divide your total lb/hr rating by 6 and you have gal/hr.
Hope that helps

Very good question. I've been looking at finding a definite answer for for the proper inline filter when using intank pumps.
I've found the answers plenty of times for an inline pump with a pre/post filters.

Here in SW FL, the 93 octane I get weighs 6.2lbs per gallon and the 100 octane unleaded is heavier (just cant remember the actual weight)...
Ive seen weighed gallons from people up north who have weighed their 91 octane at over 7lbs... So if you want to be exact, get a precisely measured gallon of your preffered gas into a container and weigh it. Then of course weigh the container empty and subtract that from your total.

Ive never seen or heard of anyone using 6lbs as a weight number have problems, especially since you want more flow than neccessary rather than just enough.

I cant remember if the formula uses actual weight data, but if it does, using 6 will get you close. AFAIK, injector companies check flow with a solvent, not gasoline... And AFAIK, the solvent also weighs 6lbs.

I would think that this formula is in the stickies somewhere though.
