I’ve read about them going bad, don’t recall what mileage or age.

Got ss running great , what flowmaster muffler would fit best, also what K-N air filter for stk airbox. TERRY

That is your update?

Why not spend a few words and tell us what fixed it?

One thread, one problem please.

I responded a few weeks ago that problem was the high pressure mechanical pump on engine, tank pump had 70 psi, HP pump only had 600 psi , nobody I talked to had ever seen one go bad [only 56k mi. how about [filter & muffler recommendations]

Open another thread.

You never said that you replaced it, just that nobody had heard of it going bad.

Glad you got it fixed, the K&N filter is listed online, you might need to wash it and lightly re oil it.
The muffler question is a matter of tastes, you want dual mufflers, FiremanGeorge has that set up with Flowmaster mufflers

No duals on mine. SSfan has the dual Flowmaster HP Shorties.

You have single Flowmaster?
