The Check Valve (one way valve) is used to stop the fuel from draining back into the fuel tank because the original one in the fuel pump is old and leaks.
Easier to install external Check Valve than to change fuel pump and costs less.

Yes, it is an original BMW part. Part is $2.25USD from Steve Haygood in the US but should be able to find in Europe at BMW dealer or order from dealer.



it' s a retrofit part for a 1990 bmw 735 IL

P/N is 16149068988 Check Valve for Fuel Pump

Thanks on information.Not sure yet where is the problem.Today,chek air inteake manifold,ajust spark plug clearens...I think that the basic problem its idle speed...Actualy,I have couple of problems.I have install on my car LPG(Liquid Petrol Gas),and when the engine its on idle speed,sometimes just die,or start to go up and down from 600 to 1200 rpm.Maibe Idle valve its problem,not sure.

Try cleaning the throttle body, may also be your MAF.

?...I have this car 5 years,and from the begigning I install LPG becouse its half of price of gasoline.I go on the Job every day with my BMW.Its 90 km every working day.In one year its about 30.000km.In five years its 150.000 km.The engine its in great shape,and so far never have a problem with LPG.LPG its god for the engine,gives longer life, and for the nature also.So,my problem its not becouse I install LPG,definitly.
