BrendanD Posted April 16, 2014 Share Posted April 16, 2014 A frustrating day....Planning on taking the GT6 Mk3 from London to Yorkshire for the Easter weekend. Went out to try and get the new exhaust mounts fitted, but failed (another story).. car died on the way home, started again after 20 mins fiddling.Died again after 10 mins, kept starting a bit then dropping off again. Tools out with help of a passing Vespa rider, dry plugs, spark. No fuel pumping... then a weak intermittent pulse. It was enough to get me home a mile though.This is the 2nd pump in 4 months, and it was a NOS one. The first one had a 'thin' actuating lever that kept falling off the cam, god knows whats up with this one, but I somehow need to get it fixed tomorrow whilst juggling work :-((( (we only have Triumphs and the Spitfire needs a new diff) Quote Link to comment Share on other sites More sharing options...
BrendanD Posted April 16, 2014 Author Share Posted April 16, 2014 OK, dismantled it. Its a NOS 'old EU' Italian one without a manual lever (I think Moprod).All is fine except the 'output' valve had fallen apart. The valves consist of just a plastic disc held by a small spring against a brass ring which is pushed into a hole in the body. The brass ring is not at all a tight fit...I've re-assembled it and had a tap at it with a hammer and screwdriver to try and burr it a bit, but its not something I want to rely on! Was there perhaps some glue that's been dissolved by bloody ethanol???Any ideas?And any suggestions for a decent mechanical pump? Quote Link to comment Share on other sites More sharing options...
nang Posted April 17, 2014 Share Posted April 17, 2014 If you're not too fussed on originality why not fit an electric pump ? Did this on my Cortina and hasn't missed a beat since also easier starting as carb is filled almost instantaneously.Tony. Quote Link to comment Share on other sites More sharing options...
CHRIS211083 Posted April 17, 2014 Share Posted April 17, 2014 Brendan, Ive just said this on another thread. I used a Huco low preasure pump designed for use with carbs. It fills the float bowls and then cuts out. Its nice as you can hear it prime when you turn the ignition on but cant hear it when the engine is running. It also sucks aswell as pushes so can be mounted anywhere. I had mine on in the engine bay and it never missed a beat. Really a great bit of kit. Some people have a second car but I just have the spit at the time and this was one of the things that made it so reliable. Chris. Quote Link to comment Share on other sites More sharing options...
toolmaker Posted April 17, 2014 Share Posted April 17, 2014 hi brendan, been reading your thread with interest, i have heard in the past that the italian pumps are not so good.one is fitted to my gt6, although i have not fired it up yet.the huco pump that chris suggests looks the boy for the job, i am not one for origonality so its one of them for me.just had a look they are about £55.hope you can sort it out brendan.

BrendanD Posted April 17, 2014 Author Share Posted April 17, 2014 Thanks GuysWell I've got a temporary fix for the weekend (600 mile trip planned), so hope it holds...For next week I've picked up a 'glass bowl' AC Delco pump as it has replaceable decent parts and you can see whats going on...I just don't feel comfortable with an electric pump...Funny for the first 22 years of driving triumphs I never had a single fuel pump problem, but they have let me down 4 times in two years now..

rotoflex Posted April 18, 2014 Share Posted April 18, 2014 You're having a run of bad luck. Throw a Facet cube pump & a few yards of zip cord into the trunk for insurance & peace of mind until it gets settled. Quote Link to comment Share on other sites More sharing options...
CHRIS211083 Posted April 18, 2014 Share Posted April 18, 2014 I agree with Rotoflex, you have a known problem so use the seven P's.Chris. Quote Link to comment Share on other sites More sharing options...
BrendanD Posted April 18, 2014 Author Share Posted April 18, 2014 Plan on doing pretty much the same. I'm putting a spare pump in the boot... Quote Link to comment Share on other sites More sharing options...
Tim Bancroft Posted April 18, 2014 Share Posted April 18, 2014 BrendanI use a Huco type on both the GT6 and my saloon. Excellent units, easy to wire in a inertia switch. Seriously, I was enjoying the same issues as you, no problems now!!! Quote Link to comment Share on other sites More sharing options...
BrendanD Posted May 4, 2014 Author Share Posted May 4, 2014 Hi, an update on this...As I had no opportunity to acquire a new pump I had to take the 'temporarily repaired' pump to the Yorkshire dales at Easter. Unfortunately (in spite of looking intact) it progressively failed to deliver at higher revs so we ended up doing the last 100 miles home courtesy of the RAC (disappointed)I now have a Facet electrical pump and all is well. except.... when the car gets hot (not engine temp, but generally) after a good run / in traffic, the pump starts making an awful 'clicking' racket that drives me bonkers... is this usual??

CHRIS211083 Posted May 4, 2014 Share Posted May 4, 2014 I've heard of them doing this from alot of people. Thats another reason I got the Huco pump. However I've never had one so see what others say.Chris. Quote Link to comment Share on other sites More sharing options...
