Fuel filter to use with Summit 4bbl carb

[Neglected68]

Before I pull the trigger on buying the Summit 600cfm 4bbl carb, I have been trying to figure out what else I need to get the upgrade done. One major question left concerns the fuel filter. The online literature for the summit carb states that it has an AN fitting to the fuel line. I'm not sure what filter to use. Can I mount it directly to the carb fuel line? How do you guys have your fuel filter set up?

I like the idea of the glass filter that MarkStang described in a recent post. Are there any downsides (other than breaking when accidentally smacking it with a wrench) to a glass filter?

Thanks!

It's not smacking it with a wrench you have to worry so much about. It's having it vibrating against something and breaking that it the typical problem...and it's a very real concern. By the time you realize what has happened you have a very large fire being fed lots of gas under your hood.

That said, I've used them for 20+ year with no issues. Just make sure to install it safely if you go this way. I use them just for initial engine installs as it makes fuel supply verification pretty darn easy.

I use the standard wix inline filter can that has a 10-20 micron filter. At $3-4 each you can simply toss it away once a year.

Im using one of these

Bolted directly to the carb. The housing is a little expensive, but then you can just change the elements.

The filters for those are only 40micron at best.

I have the tank filter just like we all have. Then there is that space from the inside fender where the fuel line comes in. It is from this part of the fuel supply to the pump that I have the glass filter connected with 50 psi fuel rubber line. It sits in mid air with nothing around it but air. I have always had this type on my Mustangs so I can see the fuel more than clean it because Up by the carb I have another metal canister fuel filter. I could put another filter in the ca b like I have had before right where the fuel line goes in, that part that screws out I have seen can be integrated as a filter. But... no need. I know glass can break but it never has, the glass is pretty darn thick and if it did break the car would be out of fuel and cut off with gas flowing from the tank if you are down hill. Level I have almost no gas loss and I know this from my recent escapades on the side of the road. I still can not figure how it could break. I think if I hit it with a hammer it would bounce from the rubber suspended hose first.

Is the stock fuel pump strong enough to push gas through a 10 micron filter? I really don't want to replace the pump.

I don't know if I want to spend $$$ on a fuel filter unless I really need it. I see 40 micron filters in the summit catalog for less than $30, which is already 10 times the price of the stock filter for my 2 bbl carb.

Get the wix filter mentioned above (napa gold # is 3033 for the same filter). It works just fine, is a low micron filter, and is cheap.

That is how mine is too. If the glass did break, your supply to the pump is cut off, vice the pump being able to continue to push fuel onto the engine.
