Greeks Posted January 29, 2016 Share Posted January 29, 2016 Hi allI'm after an electric fuel pump to feed the SUs on BOB (worked Mk1 2500)... I believe I need something around 3psi. I see there are Facet red tops, and that the cube style are way cheaper. What do people recommend? Quote Link to comment Share on other sites More sharing options...
piman Posted January 29, 2016 Share Posted January 29, 2016 Hello Greeks, I'd select an S.U. pump myself, but that certainly is not the cheapest option.Alec Quote Link to comment Share on other sites More sharing options...
uksnatcher Posted January 29, 2016 Share Posted January 29, 2016 Facet Silver Red or Blue tops all shove out 6-8 psi.....great pumps but you will need a regulator to maintain 3 psihttp://www.glencoeltd.co.uk/facet-fuel-pumps/facet-cylindrical-pump-12v-24v/Cube or solid state pumps don't need a regulator as rated 3-4.5 psi...just ok for SU's with good gaskets on the float bowls 😉http://www.glencoeltd.co.uk/facet-fuel-pumps/facet-solid-state-pump-12v-24v/Don't forget its supply on demand and the Facets flow very well IE cope with vapour lock on a hot engine, compare that with a mechanical pump that maxes out at 2.5 psi and pap modern fuel that evaporates as you look at it I use a silver top and a regulator set at 3psi......no probs on a hot and sticky 1500 spit Quote Link to comment Share on other sites More sharing options...

uksnatcher Posted January 29, 2016 Share Posted January 29, 2016 Them links are just for info Greeks, as you will see some of the solid state pumps will offer way to much PSI for the SU's to handle. SU's are rated at around 4 psi max, my 5 psi silver top on max makes the float bowl gaskets leak, 4psi they 'sweat' with old gaskets....3psi no probsShop about and the solid state pumps designed for carbs are very affordable without extra expense of the regulator....I just wanted a bit of control of the fuel pressure hence the way I went Quote Link to comment Share on other sites More sharing options...

Why not stick with the mechanical one?Nick After 18 months of a continual problem (what seems to be fuel starvation in hot temperatures at high rpm and particularly when running up steep hills!) that I can't seem to rectify any other way, I figure it's the next option. My spare mechanical pumps are beyond economical repair and the electrical route seems as cheap as mechanical. Quote Link to comment Share on other sites More sharing options...
uksnatcher Posted January 29, 2016 Share Posted January 29, 2016 My prob was standing traffic/hot conditions no airflow past carbs coupled with low revs with the mechanical pump, also sartup from hot engine. Double skinned heat shield helped but still had to fit elec pump.Upgrading to an extractor/branch manifold created even more heat but i had fitted the elec pump, and happy days.....primes the carbs almost instantly, i assume the saloon has the same heat issues?

Nick Jones Posted January 29, 2016 Share Posted January 29, 2016 Is the problem affected by tank level at all - ie better with a full tank? Modern fuel, especially that containing ethanol, which seems to be most these days, is very prone to vaporisation and the tank outlet can be restrictive. Possibly the combination of temperature (worse in Oz than here!) and fuel volatility also cause cavitation in the valves of the mechanical pump, spoiling it's efficiency. Doubt it's vaporisation after the pump when running hard. It's not just running lean at the top end due to needle selection is it?Lot's of folks had vaporisation problems in the mountains on the 10CR 2013, which seemed to be related to crap fuel with lots of ethanol mixed with highish temps and high altitude.Nick Quote Link to comment Share on other sites More sharing options...
iggy Posted January 29, 2016 Share Posted January 29, 2016 hi ive fitted a facet posi flow 1.5 to 4psi model no 60104 in the boot of my mk2 2500 £30 ebay, admittedly i havnt driven it on the road yet as ive got more work to do. but it primes instantly no noise but you must use anti vibe mounts and fit it near the fuel tank, il see how it goes when the cars on the road Quote Link to comment Share on other sites More sharing options...

But, the worst it's been was yesterday when my wife had the problem at high temps at 2,500 rpm up a very steep hill ... and fuel light was flashing.I don't see how the needle selection would relate to heat and hills...?However, this talk of float bowls reminds me the gaskets could definitely be replaced. Could they be leaking on hills? Quote Link to comment Share on other sites More sharing options...
Nick Jones Posted January 29, 2016 Share Posted January 29, 2016 In the saloon the bottom of the tank is at a very similar level to the fuel pump, so when the tank is full the pump has hardly any work to do. Perhaps more importantly it doesn't have to suck at all which makes it much less likely that the fuel will turn to vapour. Also, warm fuel turns to vapour more easily than cool fuel.The needle comment isn't directly related and is probably a red herring if the car has previously run well with the same needles fitted.Nick Quote Link to comment Share on other sites More sharing options...
nang Posted January 30, 2016 Share Posted January 30, 2016 I fitted a Facet 60104 pump in a Mk5 Cortina (similar engine size.) I didn't fit it in the boot as recommended but low down in the engine compartment. No problems with it while I owned the car. Rubber mounting is essential though.Tony Quote Link to comment Share on other sites More sharing options...
don cook1 Posted January 30, 2016 Share Posted January 30, 2016 "...when my wife had the problem at high temps..." Hi Graham, get a new wife if that's all the problem is.I have a Hucco fitted to my GT6, fit and forget, no regulator required. Quote Link to comment Share on other sites More sharing options...
Greeks Posted January 30, 2016 Author Share Posted January 30, 2016 As ever Don your kind and insightful advice is amazingly ... erm ... insightful. However, whilst perfectly sound from a technical perspective (and i've run this past a few mechanical engineer friends, don't worry) my back of the envelope calculations, rough as they are, suggest that a ~$100 electronic fuel pump, or even a $500 carburettor overhaul and a solemn promise to pay more due attention to maintenance, is considerably cheaper than a replacement wife.Of course there's the exchange rate to consider, because it depends on where you source the new wife from, but regardless, what I discovered after perusing the normally closed books of the divorce courts, is that wives ... you won't believe this bit ... actually appreciate in value, rather than depreciate! And bizarrely, their value follows no normal economic rules. That is, when global commodity prices drop, spousal values actually remain exactly the same. When supply increases, no change. Incredible. Nope. I'm stuck with a wife that first saw my car before she saw me and made a huge assumption that i'd be worth meeting, and then, once ensnared, let me buy another the same as soon as I arrived in her country ... even though I had no proper job 😎 (And she's even potentially entertaining CV axle and hub upgrades - for the car of course, not her... or me.) PS - please send me your Huco - i'll PM my address to you.Quoted from Don Cook "...when my wife had the problem at high temps..."

Greeks Posted January 31, 2016 Author Share Posted January 31, 2016 So, interesting discovery today. One of the valves in the mechanical fuel pump was half in and half out. Will see if fixing that's going to make any difference. Quote Link to comment Share on other sites More sharing options...

Tim Bancroft Posted January 31, 2016 Share Posted January 31, 2016 Mr Reeks,I second Mr Cook's advice (about the Huco), bless him eh!Have a Huco on the Saloon and the GT6, no faffing around with regulators, no issues. The saloon's Huco is hung of the block, whilst the GT6's is hung of an engine bay valance. Both work very well, The Saloon romped up the Dolomites last 10CR!As I said on another thread, good to hear from you.BTW I understand Mr MacDonald is still on the planet!

32valves Posted January 31, 2016 Share Posted January 31, 2016 I've been using an FAI electric pump for the last 10yrs, on two different cars. Never a moments trouble with it. Unfortunately they don't seem to be widely available. Quote Link to comment Share on other sites More sharing options...
