Has anybody had to replace their fuel pumps? I have had recurring leak issues on the copper washers (against the pump houssing), annealing them or replacing several times. The issue appears to be the small sealing surface on the pump housing itself. While I managed to get one pump more or less leak free, I stripped the housing thread on  the second one trying to snug in on a brand new washer that was still leaking.

I believe these are Bosch or Bosch clone pumps but wonder if someone else has tried something new.

Hi John 

Very careful with pumps , Amperes go high over 10A , beside leaking . I use bosch 044 very good.
Prefilter inox net , outlet 12 mm , you found that to racing shops.
Oil filter Mahle OC 309

UL supplies M&D stamped pumps with 2 numbers but can’t find any details or cross reference even on their website. I’ll have to suck up the extra cost and delays in shipping to get a replacement from Wicks. 

How about a picture of your setup, sound very interesting. 

Regards, Joe
