MG TD TF 1500 - Aux fuel pump.

I would like to put a modern electric fuel pump in the line as an aux pump in case the MGB pump fails. Will the electric pump push fuel through the B pump if it is not working?? Thanks, JL

I dont know about a MGB but on the T car I think it will go thru the pump.

I have an electric pump in the back end of my TD. I can switch from one pump to the other with a flick of a switch. The rear pump will push through the front pump with no problem or damage to the front pump. It is very good insurance. Not having an MGB, I can not advise you on that matter, but see no reason for different results.

I added a mechanical pump (from a Morris Minor)in series with the electric (SU) pump on my AH-Sprite.
Again not an MGB but another SU

I have a low pressure FACET pump mounted between the tank and the SU pump on my MGB GT and have no problems passing fuel to the engine thru the SU.

James - See the article, Backup Fuel Pump in the SU Fuel Pump Articles section of my web site at: for instructions on installing a permanently installed back up pump. Cheers - Dave

PS. By the way, the SU fuel pump is just as modern as any other electric, pump on the market and can be had in an all electronic version.
