MG TD TF 1500 - Use of HP Fuel Pump in TD

As mentioned in my earlier thread about the spring in 'the53's fuel pump, I've learned that it has a high pressure fuel pump. Thank you, Dave DuBois for leading me to the verification. Now the question is -- what to do with it? This is a car that I'm fixing up just to save it from being parted out and I need to minimize the out-of-pocket costs. What's the undesirable feature of operating with an HP pump rather than the standard LP pump? TIA. Bud

"What's the undesirable feature of operating with an HP pump rather than the standard LP pump?"

None - I purposefully installed a high pressure pump in our TD and used it for about a year to see what the effect would be. The bottom line is that there was no detrimental effect in the dirveability at all. Apparently there are carburetors that are extremely sensitive to the pressure of the fuel pump, but the SU carburetors are not in that group. I did not even have to change the level of the float in the carburetors when using the high pressure pump. As long as the pressure is below 4 PSI there is no apparent effect on the carburetors.
