Rustyv8 Posted February 7, 2016 Share Posted February 7, 2016 Hi all I've a 1986 90 that had a v8 retrofitted. IT has the plate on the chassis near the rear wheel with the electric fuel pump and filter housing mounted. I've purchased 2 different filter houses and the pipe that connects it to the pump. The pipe will fit the pump, but the other end won't fit either of the filter housings!! The threads seems to be different as if one is imperial and one metric. I've checked and double checked and both parts are correct as per the parts book (hence I bought the second filter housing in case the first one was just duff). But I can't see any other parts that would fit. Part numbers in question were nrc9786 and nrc7930. All help appreciated. Thanks Alan Quote Link to comment Share on other sites More sharing options...
western Posted February 7, 2016 Share Posted February 7, 2016 NRC9786 says in this link for twin carb V8 http://www.lrseries.com/shop/product/listing/9045/NRC9786-FUEL-FILTER.html do you know what the original engine was ? Quote Link to comment Share on other sites More sharing options...
neil110 Posted February 8, 2016 Share Posted February 8, 2016 The original petrol system on the early vehicles was all imperial, UNF I think. If you can find an imperial/metric male/female adaptor in something like the Goodridge catalogue or at a local branch of Pirtek, you could fit the imperaial end of the adaptor into the filter housing then the metric thread on the hose into the other end of the adaptor. I have always found Pirtek to be very knowledgeable and helpful Quote Link to comment Share on other sites More sharing options...
Rustyv8 Posted February 8, 2016 Author Share Posted February 8, 2016 Sorry Western, I should have stated that it's got a twin card v8 in it that came from a RRC...hence my confusion as it should theoretically be the right part... Quote Link to comment Share on other sites More sharing options...
Rustyv8 Posted February 8, 2016 Author Share Posted February 8, 2016 Thanks Neil110. I was thinking the same but the connecting pipe is rigid and curved so I think if I use an adaptor at one end then the other end won't mate up correctly. Or maybe i could use a spacer of some sort on the pump to move it out a few millimetres...... Quote Link to comment Share on other sites More sharing options...
neil110 Posted February 9, 2016 Share Posted February 9, 2016 Ah, sorry with you now. I wasn't paying proper attention earlier. I have an early 110 with a V8 in it, as with yours I have a chassis mounted pump and filter. That rigid pipe can be a trial getting it to fit when everything is in situ and firmly mounted. I think I fitted the pipe loosely to the filter head before fitting the unit to the mounting bracket (then had the fight with the fuel pump) when I changed mine back from Diesel The part Nos you have quoted are correct by the book but I wonder if at some stage during manufacture metric fittings were substituted for the original imperial? It has been so long since I last had mine apart I cannot remember whether that pipe has olives fitted or whether the ends of the pipe are formed, If it has olives it ought to be possible to slide the olives off and replace the brass fittings with imperial. If the latter possibly a local diesel specialist place could make you up a new pipe with imperial fittings, they would probably have the necessary tooling to swage the pipe ends Quote Link to comment Share on other sites More sharing options...
Rustyv8 Posted February 10, 2016 Author Share Posted February 10, 2016 Thanks Neill. Having now measured it seems one is imperial and one is metric. Seems as you said that they just changed it in the factory I guess! I didn't consider removing the olives and changing the end.....I'll try that. Thanks.
