How do you get the regulator off the tank? The bolts just turn without coming out
So
I assume there are nuts on the inside

This is a VERY common problem with the ltr. The nuts are molded into the tank. The only way we have been able to remove them when this happens is to cut the head of the bolts off, the wedge a screw driver beside the nuts in the plastic and remove with vise grips.

You will probably have to epoxy the nuts back in the tank once this is done.

Well that sucks! Thanks for the info though.

Mine spun trying to take them off with a hand socket. Put the small impact on them and they backed right out. Just another option to try.

its a matter of properly diagnosing it. Some have, some have not fixed their problems after replacing it. Thats why i'm asking.

i read some articles of some bikes that were running real lean and it was either the fuel filter was dirty and/or the fuel pressure regulator was dirty. that you can just clean out the regulator b/c some times it get dirty.

the part that is cleaned up is #21 and not the swirl tank#14 or is it both?

If you have a gage that reads around 40 psi you can check it to see if it bad.

there really isn't ant thing to clean on it, the things that can go bad are the diaphragm and the seat.

no but if you have an air compressor and a gage you can test it off the bike.

T the gage to the inlet and plug the outlet, then apply a small amount of air to the inlet. it should bleed off any air until it reaches 37 psi and after that it shouldn't go ant higher. you may need to install a valve to regulate the air volume.

i'm thinking of going with this one


Its 4 port so it will have a bypass for the tank and a port for a gage if I want. $114.00

Or this one for only $41.00
Fuel Pressure Regulator - Adjustable - Blue 54% Off! | Fuel Pressure Regulator - Adjustable - Blue | Fuel System - Universal

bypass valve as well. The benefit to these is having a gage to verify pressure and also a larger diaphram for increased flow and longer life before cleaning. Oh ya, and they are rebuildable instead of replacing. Seems to be a better option vs the stock POS.
