Hy guys, recently replaced the lift pump and cleaned the fuel tank out. Rrplaced the wee hoses accross the injectors. Now she takes a bit of cranking before it fires up. I think fuel is seeping back down into tank when parked for a while.
Any ideas? Anyone fotted a non return valve to the fuel line?

Check the lift pump, there are some rubbish ones out there. And check pump connections.
I have a clear section of tube in the feed line just before the lift pump to check for air bubbles going either way after problems in the past.
Fitting a one way valve may just hide a problem for a while until it gets worse.
