MG TD TF 1500 - TD Fuel Filter

I would welcome comments:
I have been doing some work on my '51 and decided to add a fuel filter, as suggested by a few locals. Plan to "splice" it in toward the rear, underneath, just forward of the petrol tank. Any pros or cons?

I'd suggest a good archive scan. Has been covered many times. IMHO, it's not a good idea for the sake of your fuel pump. Bud

Jerry, that d@#mned fuel filter is what occasioned my having to remove the head on my TD (see "Ominous Engine Rattle). If you install it, put it where you can easily see it and replace/clean it regularly. Dave Braun recommends againt the extra fuel filter but recommnds that if you insist on one, install it between the pump and the rear carb. I'll not be installing one. I'll just regularly check and clean the pump filter and the screens in the carb inlets.

What Jud is referring to is an aftermarket filter between the tank and the fuel pump. The SU fuel pump and the SU carburetors are very tolerant of fine debris and have filter screens that will stop any large chunks. Placing a modern, high efficiency, sub micron filter between the tank and the pump will trap any fine rust particles that might develop in the fuel tank and in a very short amount of time, will clog the filter, limiting or stopping fuel flow through it. This will cause the fuel pump (if it is a SU pump) to stall in a current on condition. If power is left on for any period of time with the pump stalled in a current on condition, the pump will quickly over heat and cause internal damage that can't be seen, but will cause excessive points erosion - See the article, SU Fuel Pumps Facts and Myths in the SU Fuel Pump Articles section of my Homepage at: Cheers - Dave

Sorry Dave D. I got the wrong Dave again - you're both very helpful. I'll try to do better in the future. Jud

Jud - "Sorry Dave D. I got the wrong Dave again" That's because there are too many Dave's on the forums. Not as bad as when I first went to work at the Trident submarine base when it first opened up. The office I was in at first had a total of 15 Dave's in it. If someone walked through the door and hollered "Dave" nearly every head in the office would swivel around. Cheers - Dave

My mother had three sisters. All four of them married Jims. Most of them named their first borns Jim (Thankfully, I was spared). Go to a family reunion and holler "Jim" and step aside for the stampede. Jud

Sorry Jerry, we can terminate this tangent or pursue it elsewhere. Nonetheless, I am a believer in Dave's advise regarding the inline fuel filter. Jud
