Lost Pressure with Walbro 255 Installed the Walbro 255 the other week, putting out just under 60psi, great. Well a couple of weeks later I just noticed its 20psi. Have been logging for a week or so, notice my fuel trinms were going like +25 in most cells, just heppened to look at the pressure guage today under the hood and notice I'm only getting 20psi, which would explain the fuel trims.
Has anyone else experience this?

Superb, I hope its just the hose in the tank then. I thought the hose I put on had a crazy PSI rating, like well over 100psi. Perhaps one of the hose clips is coming loose. I'll open the hatch and take a look at the weekend.
Thnks for your input.

I took a look in the tank, picture attached.
Sure was a hose clamp problem. thought I had that sucker tight. All reclamped and got over 60psi of pressure on the rails now, used to sit between 57 and 60psi, the guage says about 64psi. The hose is rated at 12 bar, which I guess is about 180psi, so I should be within spec there.
