Ok Guys I have a hard start problem when warm or hot so I thought I would try the Fuel check valve,I have a few questions.
Were is the old check valve does it have one?
Can I get this part at my local store or do I have to get it at BMA?
I sent BMA a email for a price and shipping cost to New Zealand.
What does this check valve do.
I had a look at http://www.bmwe34.net/e34main/trouble/535ihot_start.asp
Thanks
The fix kit from BMA is an inline valve that goes on the fuel line, under the access panel in the trunk
The valve keeps the fuel system pressurized so starts are a snap.
when that one fails you can use the inline as a replacement. The check valve keeps the line pressurized all the way from the fuel pump up to the injectors, this prevents vapor lock from ocurring since the boiling point of the fuel is much higher when its under 35 psi than at atmospheric.. So it serves 2 purposes , 1 to ensure that fuel is right at the injectors when you first crank it, and 2. to prevent vapor lock from occurring in the fuel line

I think the p/n is no longer up to date, latest one should be 16141179282.
Copy that. It might be and it is not the first time that local parts store will look at you funny when you ask for it.
I phoned BMW "sorry parts closed till monday"
So I phoned 4 part stores No No No No.
That number Shogun, can I use that at the BMW part store? 16141179282
That part number was given to me about 6 months ago from a guy in Germany. On 7er.com I do the tips and tricks corner and had posted the copy from BillR. So some people complained that they could not get the old p/n and someone mentioned this one. But I assume you can use any other check valve, as long as it lasts 3 bar.
Ok thank you :D
I Phoned BMW and the guy did not know what I was talking about,I said would a part number help he said "yes" so I gave it to him and he found it "Oh I have never seen one of those before Where did you get the part number" I reply from the internet (Thank's Shogun)
$92NZ 7-10day from germany.
BMA has them for $26USand$28US to deliver.
So they work out to be the same price all up so I will go with the stealer and will post when fitted.
