Fuel Pump

Post by Sally Carroll » Mon Jan 10, 2005 10:00 pm

Recently went out to start our TC and couldn't even get the fuel pump click. Decided it must be the battery. NO Sirs it was the ignition switch. . being dicey contact point on rotation was not making good connection. . . Some of the guys can tell you how to check the pump on place but out of system. . assuming the lines are clear and the 3 essentials are present. . .Fuel, Spark and Air. Sally

Steve The fuel pump should be self priming. Try disconnecting both fuel lines from the pump and connecting the pump to a battery. It should tick furiously. It if does, I'd suspect a line blockage, if not I'd suspect either incorrect polarity or a dud pump. Mark Jablonski Melbourne Australia

Well, I took the pump off the car hooked it directly to the battery and it made short buzz then nothing. I took my old pump (same exact model) and it ticked merrily away. Appears I have a bad pump so packed it up and sent it back to Moss for replacement. Put the old pump temporarily on the car and it pulled gas as well as identified a leak in the line. Two steps forward one step back. The saga continues. Steve Plath TC5731

Peter, Nothing, but the previous owner left the car sitting for years at a time so the fuel tank and carbs were full of sticky varnish. I boiled the tank and rebuilt the carbs. I also replaced all the fuel lines and the pump was just something else I thought should be replaced. Steve

G'day Steve, Not following this thread with due attention, therefore I presume this inoperative pump returned to Moss to be a new item? It's not uncommon for brand-new pumps to be non-functioning. The obvious check is to clean the protective wax off the points. I fitted a brand-new out-of-the-box spare pump to our 'V8GT by the roadside when the original 30 year-old unit cried enough. A shitty job on an MGB. Cleaned the points, fitted, didn't work. Remembered an old mechanic's advice... removed pump, dismantled, and 'flexed' the diaphragm... reassembled, fitted and it worked. Still is. It's not much fun to do this with B-doubles roaring past just metres away with dust and garbage swirling about, and petrol running up into your armpit. If you get a replacement from Moss, FWIW, pull it to bits and give the diaphragm a wake-up call before fitting... albeit an much easier job on a TC than a modern.

Gents the previous advice is valid regarding massaging the pump diaphragm, As a matter of fact the new pumps with points come with a letter advising you that you will not void warranty if you remove the cap and clean the points, also the diaphragms do stiffen up with age (and age varies). BUT in defense of Moss Motors they only sell the pump ( original equiptment) made by Burlen Fuel Systems, so the statement should have been to check any new pump regardless of supplier.

Fuel pump

Post by Len & Judy Bonnay » Fri Nov 09, 2007 2:02 pm

Group, I am looking for someone who has experienced the same thing! A friend has a totally restored TF. For the second time his SU fuel pump has sprung a leak. Upon disassembly he discovered that the rubber diaphram had softened to a goo-like consistency. We figured this to be due to our modern gas and the various additives such as ethanol. Two problems have surfaced: The first is - how does one remove the pump with a full tank of gas without losing it all over the floor? We wish to install a shut-off but cannot find the correct size for the stock pipe. The second problem- what can be done with regards to replacing the pump? We wish to remain original. This may seem like an MGTF problem but obviously could easily be an MGTC one as well. All suggestions appreciated. Len Bonnay (TC8154, TF6102) [Non-text portions of this message have been removed]

Len, Drain the tank via the drain plug situated in the bottom of the tank (if you have a drain plug fitted in your tank) Alternatively if no drain plug, syphon out the fuel using a plastic tube. Replace or rebuild the pump. You can get all the parts you require (or a complete pump) from Burlen Fuel Systems... http://www.burlen.co.uk/ Alan Webster Sutton Coldfield UK TA 3239 TF 2295

Len I am surprised that you are having a "Goo" problem I assume you are using new pumps if so these are made by Burlen Fuel systems in UK . I would assume that they are using the same material in TF pump diaphragms as in MGB, MG spridget , and I have had no problems with the ones I am selling. Is your pal using some sort of fuel additive? ? As for fuel shut off valves try a marine supply, or? place like Pegasus racing www.pegasusautoracing.com?they are in USA and may have what you want.

I've been looking for a motorcycle shut-off that would screw into the fuel tank, have a filter screen, and the fuel line would attach to the other threaded end. So far, no luck. You might be able to find a shut-off with compression fittings on both ends. 5/16" copper tubing was used for the fuel system. Stick a sharpened pencil into the end of the fuel line from the tank. So a little gets on the floor. Otherwise, drain the tank. John Seim Irvine, CA
