Wanted: fuel pressure regulator for an 1800E
 

Hi, can anyone help me get an 1800E running? The two pipe regulator (on the heater box) is faulty and does not hold at 30 psi. Cheers Keith

Two pipe is a description that is somewhat open to interpretation. If two pipe means one inlet and one discharge port as used up to 1971 then exact reproductions are no longer available. If you mean two inlet ports with the bottom discharge port as used the 1972 and later cars mounted in the middle of the fuel rail, it 'may' be available. A touch expensive.

Unfortunately it appears to be out of stock; but, if you search the part number 243129 you may find that a local Volvo shop sells it - at an even more egregious price.

The two inlet port regulator should substitute for the early single inlet port regulator just fine if you cap off one of the inlet ports with a suitable rubber pressure cap. 243129 appears to be a later part number equipped with threads around the bottom discharge port. I expect that the threads were added so that it could be used in the early bracket or just kind of hung from the middle of the fuel rail as in the later cars.

If you don't feel the need to have an exact reproduction you should be able to use just about any adjustable fuel pressure regulator that will work with a base fuel pressure of 30 psi. You should be able source one from any supplier of tuner parts for Asian cars. These regulators will have a port to connect the intake manifold to provide a pressure reference signal. Just leave this port vented to atmosphere for use on the D jet system.

When I was looking around earlier, I did find a particularly nice adjustable atmospheric referenced fuel pressure regulator from Delphi. It almost looks exactly like the original Bosch FPR and has the correct 8 mm hose barbs so no messing around with fittings. Its Delphi FP 10545.

As a bonus, its even cross listed to the 1800E in the product reference literature.

Thanks very much

As helpful and informative as yours (and some other people's replies to other requests/questions) are, when someone in the UK is looking for a part on a UK owners club forum just how useful is it to reference outlets on the other side of the Atlantic? Those suppliers are easy and convenient for people on that continent but usually a last resort if you live in Europe.

But all help is useful - even if it just gives one a lead to finding a suitable part.

Thanks 142 Guy as just ordered one from RockAuto

I merely linked the Rock Auto website because it had a nice picture of the fuel pressure regulator and demonstrated that the part is available as opposed to being out of production. You may not want to deal with them; but, Rock Auto has the great advantage that they actively maintain their on-line inventory records as opposed to some vendors who will take your order and then three days later send you an email cancelling your order because its NLA. With a little initiative, the Google search bar and the part number it should take you about 30 seconds to find out whether there are any vendors in the UK that stock the Delphi regulator. You could also use the Google search bar and the original Volvo part number to find out if there are any UK vendors of the OEM part; however, if CVI and Skandix list it as NLA that generally means it really is NLA.

As an observation, since the original fuel pressure regulator appears to be NLA, 'last resort' may be your only resort. I have had to use vendors on the continent (CVI, Scandcar, Skandix, GCP) when sourcing rare parts for my 142 E. Getting parts across the Atlantic isn't a particular impediment, just expensive. Its part of the vintage car ownership tax.

I have used Rock Auto before for some Lincoln parts and could not believe how quick and easy it was for them, I did not think about searching them for European car parts so thanks again :teeth_smile:

Keith and 142 Guy, this is a great example of how helpful this forum can be.
And Underdrive, as you say, “last resort” is exactly applicable in this case.

Ordered 28th, delivered 30th, fitted 1st October and all running fine. $70 all in so all good.
