Title: Fuel Filter question
Post by: JackConrad on March 21, 2007, 03:13:52 PM

First, a little background. I have a small Racor fuel filter (I think it as a model 980908, Filter R12T) It has 4 threaded openings in the housing near the top. 2 have arrows indicating fuel IN and 2 have arrows indicating fuel OUT. In it's previous life it was on a generator, one fuel line in, 1 fuel line out, the other two openings were plugged. According to my manuals, my generator consumes a max of .8 gallon per hour at full load and the ProHeat uses .3 gallon per hour when running. OK, here is my question, Can I run a 1/4" or 3/8" fuel line in and 2 fuel lines out, 1 to my generator and 1 to my ProHeat? Thanks, Jack

I think I found the answer to my question, but would like any BTDT experiences. I found Racor (now Parker) website. They show 2 housings that use the R12T filter. Incidentally, the "T" means a 10 micron filter, "S" is 2 micron and "P" is 30 micron. Is 10 micron adequate or should I look for a 2 micron filter? Both housings have a maximum flow rate of 15 GPH. Since I will need approx. 1.1 GPH, I don't see any problems, But I have overlooked the obvious before. Thanks, Jack

A 10 micron fuel filter is what is used on the fule pumps in stations.
I have been in the fueling service business for 30 years, course I just sold that business and as soon as my house sells I will BE RETIRED AND FULL TIMMING it in my MCI 7 with the Harley and Jeep.

Hi Jack,

I have the same filter set up on my generator [12.5], I used one of the plugged taps for my ProHeat.

I ran a 1/4" line about 30' and the gen and ProHeat both work just fine.

Good Luck
Nick-

Jack,

Detroit fuel filters are 30 microns (nominal) for the primary and 10 microns (Nominal) for the secondary.

If you go finer than 10 microns, you may end up replacing a lot of fuel filters for no real reason.

You may want to consider installing shut-off and check valves in each line. Then, if you develop a problem, both systems are not down at once. It also helps in trouble shooting.

Thanks guys for the advise. Looks like I will install it with a shut-off valve on each line and stay with the 10 micron filter. Jack
