Trumpy3 Posted May 1 Report Share Posted May 1 Regarding a collision switch, a number of members here use a switch from a LPG car system. They are relatively cheep and reliable, although you only find out it does not work when its to late. Brian Quote Link to post Share on other sites

Cheers Dave There is this one https://www.carbuilder.com/uk/inertia-safety-switch which needs the little plug you can see to the right on that page. Or do as Nick suggested get one from a scrap modern along with the bit of loom and plug to go with. Peugeot/Ford/Landrovers all have them. Stuart. Quote Link to post Share on other sites

Absolutely and to my mind an over engineered waste of time, plus with it breathing underbonnet you`ll get all the smell from it inside the car eventually. Stuart.

Re located battery I see you have a fuel pressure regulator similar to the one I have fitted but as yet need to connect. Did you have any problems that made you decide to fit one as I can see you have also an electric fuel pump fitted? Quote Link to post Share on other sites

Roy Thanks for that. I have fitted the filter/regulator as I may fit a pair of webers somewhere down the line. From what I have read it would require a regulator that can give about 3 psi with a high high flow rate on tick over with no less that 1.5 psi on high revs. (assuming I have read it right, if not then I have a fuel filter) Quote Link to post Share on other sites
roy53 Posted May 1 Report Share Posted May 1 This same system runs both 2" SU and twin 48 webers Quote Link to post Share on other sites
Drewmotty Posted May 1 Report Share Posted May 1 I generally run twin SUs but sometimes swop for twin 40s. Both run fine on the standard pump. If you want to fit an electric pump the newer Facet Posi Flo pumps are available with a low pressure output and save the complication of a pressure regulator. Quote Link to post Share on other sites

I am not sure what pump I have as under the floor. I will check on its spec. The regulator is bought fitted so I may as well finish off and pipe it up. I have all AN6 PTFE fittings and braided hose to do the job so hopefully no problem with ethanol. I will also replace the tubes at the rear, tank to pump and pump to steel tube with the PTFE braided hose Quote Link to post Share on other sites

Actual is 28.34mm. With precision Aldi caliper Thanks for that. I managed to remove my snorkel and get an inside calliper inside the hole to measure it, It came out at 1.125" and being an imperial size makes sense. I turned the plug adaptor at exactly 1.1254" and it was a nice interference fit when pressed in. The AN10 fitting I screwed in to it was 3/8NPT screwed into 3/8BSP so as the taper tightened into the plug it will slightly expand the aluminium it giving a better seal. I have yet to try it all out.. I just have to make a small bracket to lodge against the plug to ensure it doesn't come out with heat or vibration. Quote Link to post Share on other sites

The plug I made 1.125" diameter to fit into the hole in the block but just need an O ring to seal it and a retainer that I will make to stop it vibrating out. The plug I drilled and tapped 3/8 bsp (only because I have a set of taps that size) and screwed in an AN10 x 3/8 bsp fitting. The snorkel breather has been removed so I just need to fit it neatly then pipe up the fuel pressure regulator/filter I have also installed (I fitted this because the car now has an electric fuel pump) Interested to know why you went towards the back of the rocker cover and just half way up. Do you have a splash plate on the inside? Quote Link to post Share on other sites

Do you have a splash plate on the inside? No particular reason other than it worked well with the hoses, fittings and the position of the tank. There isn’t a splash plate as yet but if it needs one I will make one. Only trying out will determine that one. I needed to position the outlet so the screw heads wouldn’t interfere with the rockers inside. It’s in the middle instead of higher up because the cover is flat there but starts to curve as it gets higher up Quote Link to post Share on other sites
