Inline fuel filters + Seafoam = Bad Idea?

When I brought my VN750 in to a local mechanic for an engine pull/disassembly job to fix the balancers, I mentioned offhand how I had had problems with rust in the tank clogging my fuel hoses and carbs in an older bike and was interested in getting inline fuel filters. The problem is that the space there under the tank for adding such filters would be VERY tight, and I hadn't found any ones that I knew would fit under there.

Well, when I picked my bike back up last week, it seems he threw in a set of inline filters in the mix of work he did for me (which included epoxying some hairline cracks in the arm brackets of my fuel tank due to the formerly excessive vibration). Hot diggity!

It occurred to me though that this could complicate my current habit of adding about a 1/2 can of Seafoam every month or so to a fill-up while riding.

Seafoam is a cleanser, right? So there must be something caustic about it.

I add it to the fuel tank but it ultimately reaches the carbs and fuel jets, right? So it must be getting there through the fuel lines.

I've just added these filters between the tank and the carbs. Therefore, any Seafoam I add into the tank will pass through the filters. Is that going to eat the filters?

I'm not sure exactly what brand of filters they are (I just emailed him to ask), but I would think either it's a problem or it's not, it shouldn't matter as to the brand, right?

Shouldn't be a problem for you. I had inline fuel filters on my two KZ's and used seafoam routinely and never had a problem with them. I never put inline filters on the 750 because of the limited space, but, knock on wood, I never had a problem with the fuel system on it, more than likely because of my routine use of seafoam. You should be fine.

I've had inline filters on my bikes since I got them. No problems with Seafoam use, but the filter element is sintered brass, and I wouldn't expect any.

I'm keepin' all the left over parts. I'm gonna use 'em to build another bike!

There is nothihng "caustic" about Seafoam...it is just another petroleum based solvent just like gasoline. If the plastic fuel lines and parts in your carbs have not been distroyed by Seafoam, neither willl your plastic-safe for gasoline- fuel filters.

The only thing that I would be concerned about is if the filters will flow fuel fast enough to keep up with demand at full throttle-high speed traveling. Any filter that the stock size fuel lines fit on would have to be smaller in diameter than the lines themselves. The other concern might be heat from the motor, but other than the Vulcan....I have used inline filters before without problems.

Awhile back I had posted about some nice metal and filters that could be taken apart for cleaning....can not find the link now....

I would have to suggest that if you have rust in your tank that perhaps you need to address that by itself............


EDIT: I did find these, but they do not have the glass window...(click on accessories then fuel filters)

Yeah, I guess if it was something that would destroy the filter material while passing through, it would also likely damage the rubber fuel hoses themselves, so paranoia averted.

I don't have rust in this bike's tank, but I did have it (and still do) in another bike which now has completely stopped up carbs from it, and I have to wait until warmer weather to attempt to do something about it. So I figured I'd rather have filters to change than carbs to clean should anything similar happen in the future.

I have ridden the bike on the hwy without noticing a problem with the fuel flow, but I only took her up to around 65 MPH, it's not I was WOT. So hmm, food for thought there.

There should be no problem using Seafoam with inline fuel filters. I don't know how the mechanic installed the filters, but the clearance problem is easily solved by simply using longer fuel lines between the petcock and the carb. I would not use screw type hose clamps on fuel filters. My experience with screw drive hose clamps that small is that they go out of round when tightened, and they also look really clunky. I would either use the stock spring type clips, or nothing at all. I don't currently have any inline filters on my streetbikes, but have always used them on dirt bikes. Jerry.

I've had my bike up to 90 for short periods and cruised many miles at 75. Never experienced any fuel starvation problems due to the filters. If you think about it, the fuel lines are large enough to drain the Vulcan's tank in less than 20 minutes at full flow. Adding fuel filters would only reduce the flow slightly.

I'm keepin' all the left over parts. I'm gonna use 'em to build another bike!
