I recently replaced the Bosch injection high pressure pump on my SD1 with a pattern part. It works OK, but doesn't seem to have a one way valve, and the fuel pressure drops off as soon as it stops. It would be easier to fit an external one, than to change the pump - even if I could find the correct one new.
Many of them say not suitable for ethanol Any recommendations?
One way valve.

Re: One way valve.
Not needed at all, and most will restrict overall flow.
If you really insist on having one, what actual fitment is on the outlet of your pump ? barb ? thread ? other ?
