Hi Len, Addressing the fuel shutoff issue, I found that by putting a filter just as the fuel line comes out of the tank, or a solid state backup fuel pump near the tank, using rubber fuel line as connectors, if a fuel issue comes up, I simply use a needle nosed vise grip wrapped with some tape to squeeze off the rubber fuel line. That shuts off the fuel temporarily until repairs can be made. Just a thought.

John: Tempo (marine fitting) offers a brass fuel shutoff valve (# t-80 or T 80-A). The T-80 is an inline 1/'4" valve with male & female pipe ends. The T 80 A is 1/4" ball valve with 1/4" male pipe on one end & barb for 3/8' hose on other. You would have to use adapters for other sizes & an inline filter. Bill TC 4926

The resistance of the coil in an SU fuel pump was quoted as being 6 ohms a few weeks ago. I have measured four pumps and they range from 3.6 to 4.2 ohms, will these overheat in use?..... Bob. Wales UK. [Non-text portions of this message have been removed]

Any advise on sealants or tricks that can be used for the fuel pump. Was leaking tore it apart,cleaned installed a new gasket etc. Worked fine for about a day then started leaking again.

Thanks,

Mike

Mike, You haven't told us where the the leak was. Was it a brass based pump or a die cast pump? Peter

A die cast pump, It's hard to tell exactly where the leaks coming from but seems to be from the gasket flange and not the diaphram side.

Mike, Burlen supply two gaskets to be used with the die cast pump base. The first, it's obvious which one, goes between the two die cast parts. Before fitting this gasket ensure all the mating surfaces (including both side of the thinner die cast part and the base of the coil housing) are flat and burr free by rubbing on a sheet of fine grade wet and dry resting on a flat surface. The first few passes will witness if any of the mating faces are seriously distorted. This will also remove any remnants of the old gaskets and diaphragm. When reassembling the parts I never use any gasket compound and never use the gasket supplied to fit between the die cast base and the diaphragm. With the rubber diaphragm trapped between the base and the coil housing it seems to me to be superfluous and potentially provide another two interfaces that could eventually leak. There should be a washer that fits inside the cavity that closes the outlet connector and another that fits inside the filter housing. The inlet connector has an external washer between it and the die cast base. When tightening the six 2BA screws ensure you have a screw driver that fully engages with the slots in the screws. Progressively tighten the screws in turn as much as you can. I've never stripped a thread yet. That's it. The only other possible place a pump can leak is from the drain hole in the coil housing which should be orientated above the filter as the pump is assembled and vertically downwards as the pump is fitted onto the bulkhead. If it leaks from here you have a serious problem. The diaphragm is split. If you need more help and are located in the US contact Dave Dubois (http://homepages.donobi.net/sufuelpumps/). If you are on this side of the pond contact me again off list. Regards Peter

Not only that, but Mike's 1st. email (on the 9th.) never graced my inbox. In fact, there was only one email (from Steve Steirman) on the 9th. and none on the 8th.   In addition, I am STILL not getting copies of emails sent to the list, which is why, when I remember, they are Cc. to myself. I believe this happens to others on this list, and also on another I belong to. Any ideas???   cheers   Roger Devon
