Paul Amey Posted February 23, 2022 Report Share Posted February 23, 2022 I'm thinking about fuel pumps now. My Vitesse came with a very noisey electric fuel pump on it. I have a spare pump. But I'm wondering should I revert it back to a mechanical pump like it had when it left the factory? Link to comment Share on other sites More sharing options...
68vitesse Posted February 23, 2022 Report Share Posted February 23, 2022 I thought about converting to electric after breaking two mechanical fuel pumps, there are early and late ones for the Vitesse, but stuck with a rebuilt mechanical original. Some threads on here about the quality of the repro ones, also I would have wanted to wire in some sort of auto shut-off for an electrical one,such as wiring involving the oil pressure switch or alternator warning light for example.

daverclasper Posted February 24, 2022 Report Share Posted February 24, 2022 If buying repro mechanical and pressure too high, apparently a 3mm gasket, to space it, has cured the issue (can't remember where I read about, I'm afraid) Link to comment Share on other sites More sharing options...
Pete Lewis Posted February 24, 2022 Report Share Posted February 24, 2022 it would be on here theres a good few posts about spacer ,thick gaskets, cutting down the spring use the old spring are the main options Pete Link to comment Share on other sites More sharing options...
johny Posted February 24, 2022 Report Share Posted February 24, 2022 yes its in the Triumph workshop manual so applied to replacement pumps even back in the day! Link to comment Share on other sites More sharing options...

rogerguzzi Posted February 25, 2022 Report Share Posted February 25, 2022 Hello All I had one on Spitty before EFI they are good as you can fill the floats before engauging the starter(I know about the oil bit but a good filter on a good engine is no problem!) I am fitting one to the Vitesse and getting rid of the noisey one that pumps all the time and needs a regulator. Plus they come with a 5 year warranty Roger ps do fit a cut out switch though.

Paul Amey Posted February 25, 2022 Author Report Share Posted February 25, 2022 Quote Right, thanks. Those wiring diagrams are really helpful. I think having read all that info, I'll got with electric pump on a cut out. Link to comment Share on other sites More sharing options...
DerekS Posted March 16, 2022 Report Share Posted March 16, 2022 Evening all, I'm going to fit one to my 1500 Spit, in the engine bay. The very basic instructions dont show the orientation. The supplier reckons mount it vertically with the pipework on the top but this would leave the manufacturer's label upside down, which seems strange. Also, where EXACTLY have you fitted yours? Any advice would, as always, be very much appreciated! Derek. Link to comment Share on other sites More sharing options...
NonMember Posted March 16, 2022 Report Share Posted March 16, 2022 What make and model is it? Most electric pumps are not designed to pull fuel along the pipes and need to be fitted in the boot, by the tank. My Spitfire has a Facet pump fitted to the rear axle saddle below the tank.

rogerguzzi Posted March 16, 2022 Report Share Posted March 16, 2022 Hello All Huco do both types a pusher and a sucker. I had a sucker on Spitty mounted on the baulkhead and worked perfectly Roger Link to comment Share on other sites More sharing options...
DerekS Posted March 16, 2022 Report Share Posted March 16, 2022 Sorry guys, it's a Huco 133010 suction type. Sorry about that... Link to comment Share on other sites More sharing options...

Iain T Posted March 17, 2022 Report Share Posted March 17, 2022 I fitted mine vertically on rubber mounts bolted to a galv cover plate. The plate covers the hole where the old pump was. That way I used the existing copper pipe with new hose ends. Iain Link to comment Share on other sites More sharing options...
Wagger Posted March 17, 2022 Report Share Posted March 17, 2022 My car was fitted with an Airtex E8016 pump with a fillter. I have reverted to the glass bowl mechanical one as this had no shut off and pumped at 4psi. However, it will lift fuel at least half a metre above the level in the tank. and will suck through the valves on the mechanical pump. I have used it to prime the system and drain the tank. I have left it in situ in the engine bay so that it can be connected up within ten minutes, having suffered a few delivery problems of late. If you fit one in the boot, the whole system after the pump will be pressurised, so you need to ensure all pipework can cope. Link to comment Share on other sites More sharing options...

DerekS Posted March 18, 2022 Report Share Posted March 18, 2022 Thanks for that guys, as I say I would have thought that there would have been more comprehensive instructions included with the pump. Cheers. Derek. Link to comment Share on other sites More sharing options...
rogerguzzi Posted March 18, 2022 Report Share Posted March 18, 2022 Hello Derek I think it can be mounted at any angle except vertically with the wires at the bottom! I am pretty sure I read that some where! Roger Link to comment Share on other sites More sharing options...
Wagger Posted March 18, 2022 Report Share Posted March 18, 2022 The Airtex one works in any orientation. I plumbed it 'After' the mechanical one so that it can pump directly to the carbs. It has been permanently 'Plumbed in' like this in the past. Connecting it to the ignition fuse in an emergency has proved very useful as a 'Get me home' measure. The mechanical one wil deliver 1.5lb at the carbs via this, and the Airtex will make 3psi sucking through the mechanical one. If the priming arm is tied up, the mechanical pump is disabled and acts as a filter. I can see the fuel in the bowl. It has been a very useful set up for fault diagnosis and draining the system. Not too much of a 'Faff' either. Link to comment Share on other sites More sharing options...
Paul H Posted March 18, 2022 Report Share Posted March 18, 2022 I like the tell tale clicking of the electric pump Paul Link to comment Share on other sites More sharing options...

I can see the fuel in the bowl. It has been a very useful set up for fault diagnosis and draining the system. Never thought of that when I fitted an electric pump as a pusher in the boot I could have avoided having to find unusual fittings/unions with the right threads to remove the mech pump but use its suction and delivery male screw in union pipework. I had to go to an old contractor who I used to use for Instrumentation & process control work & rummage thro his odd ball stock for the bits BUT I did also source a couple of old stock brass oil damped 3in pressure gauges Budenberg not Chinese sh*t with the range 0/100psi and a 0/10psi, handy for checking Overdrive operating pressure (mates making an electric motored jig for?) and fuel pump delivery pressure, plus chewed the fat for a couple of hours about old times and absent friends!

Wagger Posted March 18, 2022 Report Share Posted March 18, 2022 My Airtex pump works in any orientation. I am pretty sure that it is a solenoid with a non return valve. If it ever fails, then I will cut it open to find out. It seems reliable and has been used to pump fuel from tank into cans, and the other way too. I have used it in the past when plumbed in series to prime the system by connecting it in parallel with the starter motor. That way it only runs when turning the key. Takes about half as long as using the mechanical one only when the car has stood for more than two weeks. Since replacing carb bits and fitting new gaskets to the float bowls, this has not been necessary. Link to comment Share on other sites More sharing options...
DerekS Posted March 18, 2022 Report Share Posted March 18, 2022 Roger, when I asked the supplier, they said to mount it with the pipe connections at the top and the wiring at the bottom, but that would leave the manufacturer's "label" upside down! The label is etched in to the surface, for want of a better description, not stuck on, that tells me what you say is correct. Derek. Link to comment Share on other sites More sharing options...
