Unkel Kunkel Posted July 30 Report Share Posted July 30 I am considering a Huco electric pump as it seems that this is the one that one which tends to be recommended very widely in terms of dependability and it seems, very low noise. Regarding fitting it - I have seen pictures of them mounted horizontally and others vertically and yet have see some posts from folk that they should be horizontal. Are they ‘ universal’ in terms of mounting ? Have an inertia switch and wiring planned. Any views /pics would be most appreciated - about where an under-bonnet version is best suited ?

Iain T Posted July 31 Report Share Posted July 31 On my Vitesse I've fitted both vertically and horizontally with no difference in operation. On my Vitesse I currently have mine fitted horizontally on the shelf by the battery. Iain 1 Link to comment Share on other sites More sharing options...
dannyb Posted July 31 Report Share Posted July 31 I believe the Huco pump is best fitted virticle. I have fitted a Hardi - German Manufactured Electronic Fuel Pump which is very much like a huco but better made. Danny 1 Link to comment Share on other sites More sharing options...
Unkel Kunkel Posted August 1 Author Report Share Posted August 1 Thank you, guys. some say vertical, some say horizontal and looking on many other classic car sites such as MG and Elan etc with pics etc, there seem as many in each category,which makes me think it might not be critical. However, then I see some suppliers of Huco say horizontal … Link to comment Share on other sites More sharing options...
johny Posted August 1 Report Share Posted August 1 The Huco Gower & Lee web page shows them horizontal but doesnt specifically say that so might be best to ask via their enquiry form... Link to comment Share on other sites More sharing options...
Ian Foster Posted August 2 Report Share Posted August 2 On my GT6 I have fitted mine vertically, mounted off the front of the nearside suspension turret. I have a 8mm hard line routed across the bulkhead with a flexi to the pump and a final flexi to the carbs. This routing is to avoid having the fuel line immediately adjacent to the head (which I never quite understood). Ian 1 Link to comment Share on other sites More sharing options...
Unkel Kunkel Posted August 2 Author Report Share Posted August 2 (edited) The instructions with the Hüco aren’t very helpful There is ‘ top’ marked but does this mean the whole end of the pump should be ‘ Up’ ?-in which case this means mount it vertically or just the bit with ‘ Up’ should be uppermost - then that means it should be horizontal. Or… Maybe it doesn’t matter… Edited August 2 by Unkel Kunkel Link to comment Share on other sites More sharing options...
johny Posted August 3 Report Share Posted August 3 Looking at it logically the ideal is to have the discharge of any pump at the highest point and inlet at lowest so that air inside naturally tends to flow out and its easier to prime it. With the Huco that means horizontal mounting with the discharge port uppermost which corresponds with TOP plus arrow in the photo and then each connection nozzle can be rotated to suit the pipework in and out👍 I can imagine the worst orientation is vertical with the pipes coming up from below to connect at the top of the pump as this means you have the diaphragm chamber in a pocket of trapped air. However even with this set up the pump (especially when new) will probably have enough oomph to expel it.... Link to comment Share on other sites More sharing options...

Agree, It would seem then that if mounted horizontal, the outlet should be above the inlet. The Hardi, which dannyb refers to, which I think works in the same way to the Huco has instructions also suggests similar…. but then vertical is OK - I think Ill see where it fits easiest! 1 Link to comment Share on other sites More sharing options...
DaveH Posted August 3 Report Share Posted August 3 Not mine, but here’s one fitted next to the clutch master cylinder: Link to comment Share on other sites More sharing options...
johny Posted August 3 Report Share Posted August 3 Not bad but I think Id have it the other way round, connections at front and electrics at back. Course dont know if that model has the completely adjustable pipe connections like Unkels... Link to comment Share on other sites More sharing options...

I followed your advice - they responded very quickly to my query. They say horizontal with outlet upper most to avoid air lock. ‘When’ I get to fitting it, i’ll see how it can fit best… 1 Link to comment Share on other sites More sharing options...

johny Posted August 5 Report Share Posted August 5 That seems pretty low as the flow rate is up to 100l/h which is far more than even our cars can use😁 Link to comment Share on other sites More sharing options...
Iain T Posted August 5 Report Share Posted August 5 You can't trust some sellers websites! I agree even with spirited driving 20 gallons per hour should be fine. Iain Link to comment Share on other sites More sharing options...

Unkel Kunkel Posted August 13 Author Report Share Posted August 13 Learning a little bit, I think.. Huco, and the Hardi, appear to share some characteristics of the old SU pumps in that they pump until a certain pressure is reached then stop, then performing ‘ on demand.’ Quite a few others, including the cube type ‘Facet ‘ or one of the many Ebay look-alikes , ‘clack’ away continuously. Depending on the make, siting , mountings - and also the owner, it seems, these types can be noisy and quite intrusive, like having a resident maniacal woodpecker. The Hüco / Hardi option seems more appealing. Link to comment Share on other sites More sharing options...
dannyb Posted August 14 Report Share Posted August 14 I have a Hadi in the engine bay and Facet in the boot as a back up. I can switch between them. If the Hardi fails then I can switch to the Facet. Had to do this once when the Huco I had fitted failed. Danny Link to comment Share on other sites More sharing options...

Do you have the Facet / cube pump plumbed directly into the supply pipe- ‘ in series’ so to speak, or did you have to make a to make a branch/ ‘ parallel’ circuit?
