The Stovebolt Site Forums The Shop Area General Truck Talk 1941 216 engine - Fuel Filter Location

I have a '41 pickup with 216 engine. I see a lot of pictures where people have added an inline fuel filter just ahead of the carburetor. That seems like a good idea, but I was thinking of adding one ahead of the fuel pump and glass bowl filter instead. I would think filtering the fuel before it goes through the fuel pump would be good. Can anyone see why this would NOT be a good location? Thanks.

Sounds logical to me.

Im am sure not an expert on this issue,however I would say it would be OK anywhere before the fuel goes to thev carb.

I'd use it before the pump if you can, then dirt won't mess with the check valves on the pump.

Or better yet just use a fuel pump with the built in glass bowl filter, then looks original and in my experience works just as well as an added on filter. No need to cut the fuel lines either.

If your fuel pump is marginal with respect to PSI, there is a rare chance that you might get fuel starved with the filter on the inlet side of the pump. SUPPOSEDLY, the pump pushes better than it sucks.

I found this out two summers ago, when I was fuel starved in a dual carburetor set-up. I was instructed to put the fuel filter on the "push side" of the fuel pump (I had tried two new fuel pumps). This solved my problem.

I'm with what Tim says, the pumps do push better than pull, and the fuel tank positioning provides some gravity feed help - which is most of the reason that later tanks positioned low and far back in the frame started having pumps in the tank where all they have to do is push

in addition I think it's a bad idea to have a filter where it's not very visible and easy to forget about - if you have such a sediment problem that you need 2 filters, it's time to tend to the primary problem, the deteriorating tank, especially if you're getting bits of crud big enough to plug the pump valves, which of course would also plug the filter to give the same end effect, fuel starvation

In my case I have added a bigger engine and moved the tank location to the back of the frame. Coming out of the tank I have added a 100 Micron filter and a provision for a second pump in case the engine pump will not pull the fuel up to the carb which has its own filter. The 100 Micron Filter has a removeable screen to clean it.

I dunno, I put a modern in-line filter just aft of the pump five years ago and have no adverse issues with it. <CLICK>

I'm with Tiny, I've got an inline filter just before the fuel pump and a glass bowl filter just before the carbs. Been that way for several years with no problems.

Regardless of where I put the filter I try to put it in a place I can get change it without using my sunday school words!
I'm running a V8 in my 52Panel with a new gas tank and I put a filter right where it comes out of the tank and I can get to easily. Maybe this will help you in some way.

Alvin,

That is one of the reasons that I wanted to try placing the filter aft of the fuel pump (no go, in my case). Hoping to let any drips hit the ground.

I have fuel filters right off the fuel tank on (3) motors that use mechanical fuel pumps and have not had any problems.

I've put mine prior to the pump, no problem.
