Fuel Filter(s) ?

[SpidyJ]

No room between the petcock and T due to the solenoid.

Anybody install 2 filters after the T??

Maybe us some tiny ones?

the one in the tank is perfect. adding a filter reduces flow on a gravity feed system which also relies on the head pressure in the tank. u don't want to go lean at WOT or under heavy load esp when the tank has a low fuel level.

Hmmmm, good to know...thanks!

Don't add a filter.  I found out the hard way.

My belly tank has two with fine brass screens, one on the pump inlet one inline by the carbs. When I replaced them after 50-60k I took them apart and there was almost no sign of dirt.
The intank filter should be more than up to the task of keep dirt out of your carbs.

So did I. Even using a fairly large, 3/8" filter between the Pingel and the T, I ran into vapor lock issues during high speed riding in high ambient temperatures (roughly 110* heading down the highway at 85 into Las Vegas last year). It'd start dropping cylinders and act like it's running out of gas, despite having plenty of fuel. Slow down, and it'd run OK, but I couldn't go over about 55 that afternoon without it running like crap.

It was fine beforehand, and after, but it also wasn't that hot again. I tossed the filter, and the problem has not returned since, even in similar hot/fast riding conditions.

One of those things that "seems" like a good idea, but tends to cause more issues than it solves.

My '03 had a filter on it when I bought it in '16 so when It starting dying at high speeds I replaced the filter. Some problem, and the bike has to cool down before it will restart. I can understand the filter starving the carbs at high speed, but why won't it restart right away or shortly after?

Hmmm....hold on while I go out to the garage and tell my Phat Lady that according to all reports she's not supposed to be running, shouldn't have been doing so for the last 10-12 yrs. That's about as long as I've had an inline filter in conjunction with a manual Pingel petcock and Dan Marc shutoff. I've run at interstate speeds of 70-75+ for extended periods and take the fuel gauge down to under a 1/4 tank, which puts me just short of going to reserve.

The reason I use an inline filter is because I extended the intake tube on the Pingel to match the length of tube on the OEM petcock, thereby giving me equivalent reserve closely matching the OEM petcock. However, by extending the pickup tube it made it too long for the in tank filter that came with the Pingel when new. My setup works and has been trouble free for well over a decade.

I know that I do not have the extensive time or experience on the Valkyrie that many of you have,
but I put a dual outlet Pingle  and a dual inlet and outlet pingle inline fuel filter and took out the 1st Tee and ran directly to each fuel rail...I have had no issues running freeway speeds in the 90s (degrees that is)..maybe my problems are yet to come....no danmarc...I'm just religious about shutting the fuel off , if even for a 5 min. stop.

My fuel shutoff is the T, and I have a good sized large ID fuel filter in the 3/8th line and had no issues

But its tight now that I have larger coils in place..... not easy to find smaller filters with a large ID connection, most are really restrictive

then u only have one filter and not two filters. problems arise with two filters.

I doubt it was the filter itself.  If the fuel line is continuously downhill it has a tendency (accelerated by heat) to develop a bubble, an air block.  Adding a filter too often involves adding fuel line which results is some slight uphill portion.

Agreed, however the inline was in there for about 2 yrs. prior to changing over to the Pingel....a point I forgot to mention. The cover set I installed at the beginning only lasted about 2 yrs. and prompted me to then install the Pingel with the extended pickup tube. I wanted to remove the inline at that time but the Pingel filter no longer fit so I left the inline in place.  It works for me, guess I'll leave well enough alone.

I  have a filter on the Pingle in the tank and the double inlet/outlet filter...still working....not to mention the six little screens in the carbs.

Plus 1!
