YA your theory should totally work. Im going to do it next friday, that and replace the second filter on the carb line with another red aluminum "brass" filter.

Note that once you take the stock fuel pump and throw it far, far, far away, the fuel filter isn't really a problem anymore.

The fuel filter *is* a problem with the stock pump, because the stock pump is barely almost adequate, on a good day with a brand new clean filter.

Interesting point Peejay. I was assuming that the restriction was due to a fuel filter that couldn't handle the capacity, but maybe the true bottleneck is at the pump. I just installed my Carter today, so I guess I'll never know...

But I suppose in the mean time, this would still work for anybody stuck with the stock pump.

chedda_j

YA like me, but put much is a carter?

peejay

The problem is that the pump doesn't have enough excess capacity to deal with any significant pressure drop through the filter.

Put on a decent fuel pump and it doesn't mind having to pull through a less than ideal filter, it has sufficient excess capacity.

The nicest thing about getting a better fuel pump was that I didn't have to change the fuel filter every month. The pump paid for itself in the first year

Now, if you wanted to buff some turds, you could measure the line pressure (will be a vacuum) between the filter and the pump with the pump running, and check this against various other filters.

Cause glass filters are illegal for the street, and in any single racing class. You won't pass a tech inspection anywhere.

Just wondering how often do you guys find yourself changing your fule filters? The guys with the stock setup? Sorry for the thread hijack but this does pretain to what we are talking about here.

Kentetsu

Some people say to change it yearly. I can usually see a difference in power with a new filter after a few months. You probably won't see "problems" for about a year though.

OnlyOnThurs

well i do what you do i change mine every few months (probably every 3 to 4 months)

I change mine everytime I change the oil, but my gas tank is horrible!!

You thought that one dudes avatar was bad ill take a pic of mine coming up here in about 300 miles or so.

You would die if you saw my pintos filter

My avatar? lol

That was what the filter looked like when I first got the car, rusted gas tank, so bad that it leaked a river down my driveway the first time I filled to the top.

Goo now thats rusted.

My pinto gas tank is so rusted, that I have to change it every 500 miles, and when I drop the tank every 1500, I dump out 2 cups of crap. The worst thing, I can drop my tank in 2 minutes. only thing that holds it in place is 2 bolts with a strap.

haha ready for action

okay im using this pic as a refrence. Where the red fuel filter is, my line is just straight lined there is no filter there. Was that the previous owners doing? or did that line just go straight to the carb, the line beside it had the stock fuel filter and i dont know weather i should put a filter on the straight line

Kentetsu

The stock fuel filter should be located under the rear of the car, just forward of the gas tank.

85-GSL

anybody know about 13b's is there just the one rear filter? i bought a new fuel filter a few days ago but ive been majorly dragging my feet because my car is grounded because the starter is in the mail, im hoping for tuesday.

this makes me think, im going to unhook both ends of my fuel line and put a nice blast of air to make sure its clean.

hmm where can you find aftermart better fuel pumps?

That filter in the picture has been added, it was not a stock installation.

Any thoughts on this filter?

didnt know about the glass, dont race much. thanks. now i wont make
myself look so dumb in public.

another thread hijack, but for the nasty *** tank, empty all of the gas out and pull the tank. Get some chain links stick it in the tank and beat the **** out of it. Pressure wash let dry and pour red koat inside the tank. It will seal the tank and won't have anymore trouble. Let the **** sit completely open for a few days, have heard some horror stories of people replacing tanks to soon and clogging entire lines. Cheap, easy, effective. my .02cents

Specture isn't too bad they're a cheap rip off of the Russell stuff. They can be found in the States at Action Auto, and your local Shucks, Checker, Kargen. Don't know about auzzyland though.

It's purdy, but it will plug quickly if it is pre-pump. If you want one in the bay, hit the filter rack where they have the stock looking filters.

This setup might be easier!
Run a 10micron Quart Size Filter Berfore the Fuel Pump
(Mount it to the Left Rail) and then a Russel 10micron Filter before the Carb.
See Pics
I change out the Elements about every 15,000 miles in my 84GSL.
Original Cost =$42.00
Elements Cost=$9.00
