Hi all Just bought one of these from VW Heritage. Needless to say it came without any instructions. I imagine fitting is simply putting it in the fuel line between pump and carbs but it came with the two brass connectors loose, and the hexagonal nut in the middle that is over the spring was loose too. The brass connectors are tapered and if I was doing plumbing at home I would use some PTFE tape to seal them and then screw tight. The hex nut has a white seal washer under it so that should be OK. Thing is, do I need to worry about torque on the hex nut or just tighten it? Also do I need a seal of some sort on the tapered brass fittings e.g. PTFE tape. I don't want to be leaking fuel any time soon (haven't got my Firetec yet apart from anything else!) Your thoughts appreciated ps I am fitting this as I now have twin DCNF webers (on a type 4 1800) and I think it is over fuelling.
TBH I had a lot of problems with Fuel pumps and regulators (See other threads), but in the end I stripped out the lot and just fitted a CB Performance electric fuel pump. I have twin carbs on a type4 engine and it runs sweeter than it ever did on the mechanical pump, and various faceut type electric pumps (the square ones). The pump is regulated itself so needs nothing else. I figured in the end based on all my bad experiences that the fewer connections I had in my fuel line the better. Cheers.
I've done a bit of googling and it appears that normal thread lock such as loctite 243 is the way to go. People do use PTFE tape but of threads break off they can block jets etc. Job jobbed hopefully. Cheers Phil
Thanks Zed I've got both so will have a play later. Interesting to see how the regulator affects things too.
I also had a bit of trouble with a fuel regulator (can't remember which make...Kingavon or something similar)...the problem stemmed from vibration as the original bracket was weedy...make sure you mount it solidly on a bulkhead or chassis as opposed to the engine or tinware
