I'm getting ready to change my fuel filter on the 79 f350 with 460 in it. I have looked in the repair manuel for the locations but I cant find anything. I know there is the small one on the carb but is there an inline filter on the fuel line anywhere? I have not looked around really yet but I figure I would ask so I can go right to the spot it should be. I looked on the parts store websites and two of them show the carb filter and another one shows an inline filter so I bought the inline filter. The carb filter was clean.

 

Not sure if this applies to your truck, but I discovered a few months ago that my 73 390 is suppose to have an inline filter before the fuel pump, but a PO must have removed it. It would have been a metal canister with a removable paper element type filter inside. You can still buy the paper element filter refill at the auto stores. And I believe Dennis Carpenter sells the actual canister.

I run the filter at the carb and also a 'see through' inline filter before that.

 

Ok thanks. Well the one part store calls for an inline filter that is thin and metal, but the other two only show the carb filter so I was wondering if I got the right part or if there is more than the one small rock filter that goes in the Holly 4b carb.

This filter fits inside a canister that threads onto the fuel pump. Most people are unaware it's there, so it rarely gets changed.

PCSKIES...where was your inline fuel filter supposed to be? Looking for another besides on side of carb...Thanks...

 

You should check the entire fuel line all the way back to the tank, because regardless of what would have come from the factory, a previous owner could have spliced in an inline filter anywhere he saw fit.

 

Thanks! No filter other than on carb. And now brand new!

 

I know this is an old thread but just in case anyone finds this via a search, I want to see if numbers dummy and shed some light on part .C4AZ9365B. It looks like this should work on 73-79 fuel pumps, but my 75 swb fe360 f100's pump looks like this one which has no room for a filter: https://www.partsgeek.com/gbproducts...BoCmTYQAvD_BwE

I wonder if the fuel filter on the pump was only used with dual tanks on the long beds?

 

The original fuel pump was replaced at some point by one from a parts store. Some auto parts store replacements have no filter on the pump.

Original: D4TZ-9350-B .. Fuel Pump & Filter Assy / Obsolete = 1974/76 F100/350 360/390 // 1974/78 F500/750 with 330/361/391 FT engines.

 

To go with FMC's comment, yes the previous owner could have installed filters anywhere. I have a 75 460. I added large fuel filters on the suction side of the fuel lines going into the selector valve.

 

Interesting. Ive been reading those parts diagrams on f100central and they don't explicity show a diagram of the pump for the 360/390 (as they do on the 302/330 which was posted above).

The parts diagrams are however marginally good enough to show an unfiltered pump in the FE diagrams. Further, Rockauto seems to imply that (for the 360) you should only use a filtered pump with an in cab tank. Unless the flow rating is different, I'm inclined to believe that you could just slap a filtered pump on there and call it good.

 

I knew before I posted that pic that someone would comment about the caption.

This is the only fuel pump pic in the 1973/79 Ford 100/500 series Truck Parts Catalog.

The 302 pump is different, but the 330 FT used the same pump as the 360/390 FE

RockAuto is not FoMoCo. The cartridge filter fuel pumps were used from 1964 thru 1979 on myriad different car/truck engines.

Types of fuel tanks don't make a damn bit of difference!

 

I bought the fuel pump Bill listed above, earlier this year. I chose to zip tie a cutup piece of old radiator hose onto my existing radiator hose as the canister was rubbing on the back of the lower radiator hose.. Maybe I am just super cautious being an aviation guy, have seen way too much chaffing issues.

Previously I was going to install an inline fuel filter up on the frame rail but went with the cartridge fuel pump.

I do have a metal filter between the fuel pump and the carb but it will go away when I redo my metal line. I installed the metal inline before I installed the canister fuel pump.
