Now I know this has been covered before from browsing other threads, but some of my questions have not been answered so I figured I would just make my own thread. Looking for answers and opinions.
I have one of those cool glass bowl pumps I see from the shop manual I read online that there used to be a magnetic filter that would sit in the bowl I'm guessing these are hard to come by. Does anyone have a source? I haven't taken mine off and really looked to see what sort of filter is actually in this bad boy
The plan is to take the pump of and check to see if it does have any sort of filtering device other than a screen still installed. No matter what I find I plan on plumbing an inline filter into the steel line before the pump Thoughts or comments?
I've been having an issue with the truck not being able to idle without the choke being on I haven't eliminated anything but it seems like its leaning out. I'm thinking lack of fuel pressure from the pump but once again I haven't tested any sort of fuel pressures It definitely happens once the truck has driven a moderate distance if I just put around then it seems to hold an idle ok, but if I ride the highway the 11 miles to home then I sure as hell better choke her at the stop sign at the bottom. Of the off ramp Any thoughts to this
Any thoughts or opinions would be greatly appreciated
There are 2 small flexible fuel lines, one under cab that connects fuel tank and one right before your pump, these can get pretty nasty. If you have fuel in your fuel bowl, i would check/ clean out the carb, maybe a float is stuck. If you have fuel in the fuel bowl, its probably not the pump
Already rebuilt the carb. Honestly after thinking about it and looking at pictures I'm thinking the only filtering device in this truck is a screen filter north of that glass fuel bowl. The magnetic filter assembly of sorts is not in the fuel bowl (far as I can see). I'm going to clean the carb again, blow out the lines, add an inline filter before the pump (because I don't think I'm going to find the filter that goes in the fuel bowl) and check out and clean the pump. Just won't be able to do that until wifes car is out of the shop so I don't have to drive the truck to work anymore.

Please, when asking questions, list ALL the pertinent info. We are not mind readers.
What year is the truck, what series, what engine?
The original filters installed in glass bowls were ceramic, I've owned several vehicles with these. I've never seen or heard of a magnetic fuel filter.

Sorry. It was late when I originally made this post and honestly yes, it appears I was looking for some mind readers now that I refer back to my original post. The truck is a 1960 F100 with the 223l6 motor. If you look at the page from the shop manual it refers to a magnetic piece as a magnetic filter. A cartridge filter sits on top of that. I haven't taken it apart so I don't know what is in there but the "magnetic filter" is defenetliy absent.
Have you looked in the tank? My had rust flakes that would clog the tube. Those fuel pumps are pretty cheap for an after market. Probably 40-60 bucks at autozone.
I had a similar issue with my truck. My tank had dirt in it. No sock filter on the pickup in the tank. So anything in there gets pulled in to the line. Another issue is you might be sucking air somewhere. At higher rpm's your pump can overcome it, but when you hit an idle you lose that extra motion. When you get off the highway is about the hottest time for the engine. You may be boiling the gas in the carb or steel line after the pump. Is the line close to a radiator hose or exhaust pipe?

No never heard an issue with that before. Drove it a bunch of times in 100 degree plus weather and it always drove like a champ. Something has built up along the way.
There are two types of filtering systems on this pump design. The one on the left just uses a strainer only and calls for an inline filter on the carb fuel line and the other has a bowl mounted filter(s).
This design(s) was meant for visual detection of debris as there was no tank filter. The screen only was meant for pump protection only and the style with the filter was designed for both pump and carb protection. You just need to decide what style you want to go with.
If adding a filter before the pump, it should be no more than 10 microns to prevent vapor lock/blend separation (IMO).
EDIT -
I was chasing pump info and stumbled across this older post.
The MAGNETIC FILTER (9360) was meant to collect rusted metal particles (rusty tank) before fouling the actual strainer (9365).
A fuel filter should not be used before a mechanical pump (other than a sock filter - 9A011) as it may cause vapor lock and/or blend separation. A pre-pump filter is only used on electric pumps (pusher) (100 micron).
