Waterpump problem?

Oh and tomorrow they may want to pull the heads. Sounds like haggisgood experienced the same thing as I. Heats a bitch and so is a repair when you still owe 6k on an aging VX.

get this... when vehicle was in shop.. i asked them to replace my fuel filter w/ one i had already bought... as it was easy for them to access on a lift...ok if u read.. i have wierd hesitation issues.. so finally i decided to check the filter... yup.. installed w/ the flow arrow pointing towards the gas tank..lol..
i reversed it hoping it would "cure" the issue.. however as of a day later.. vehicle still does this... almost mostly within the first 5-10 mins of driving.. not nearly so bad after..
Q: is this fuel filter now damaged due to reverse flow for approx 700 miles of driving?
Q: the hesitation; around corners, when the engine rpm is low.. (10-15mph), she will hesitate.. then kick in... what is going on?... are plugs installed wrong or ??????
Might be selling her soon..... HATE to do that.. but its a possiblity..

id guess you killed the fuel pump by driving with it installed backwards

Yeah, that is crazy. Yet another reason why I try to do as much as I can myself.

Etl is probably right, fuel filter and pump might need replacing now.

I googled fuel filter direction and can't find out for sure why it's so bad to install it backwards. It possibly could restrict flow.

However, I think it was a mistake to reverse it after 700 miles. Some junk could possibly have been caught by the filter on the end towards the tank. Then if you turn it around, the end with the junk is now being back flushed towards your engine and injectors! I would change it again with a new one.

I'm on my fourth fuel filter and I always use a black magic marker to draw a BIG arrow on the filter so I don't mess it up.

Our fuel pump is in the fuel tank, so it most likely was not affected.
