Yeah Ed I remember the whole saginaw thing no= w.  It was an odd thread and I could never find the exact fitting at t= he usual hydraulic supply places.  Someone mentioned the 10mmx1.0 work= ing so I tried them and they seemed to work.  Funny thing is when I we= nt out tonight no leak, ran the engine up to 3400rpm still no leak( well at= least not fuel )...

Thank you everyone for the info on your pumps.&= nbsp; I think I am going to try the GSL392's( http://www.summitracing.com/p= arts/VPN-GSL392/ ) as their spec's call for the 10x1.0 so they should seal = without too much problem...

Hi Scott,

Hi Sco= tt,

I have used the MDS inline fuel pump (very similar to the= =0Aones Tracy sells).  I have used them for over 10 years and never h= ad them =0Aleak.  They use (what used to be called "Saginaw fittings -= I think because =0Athey were metric and used in Automobile fuel systems" -= with the small "O" =0Aring.  In fact, it looks exactly like the summi= t racing part.  =0A There is always the possibility you got a def= ective fitting or an =0Aold  "O" ring.

I have inline fuel pumps from Tracy from a while =0A = back.  They were from Napa and were the 74028 flavor( http://www.summitracing.com/parts/= CRT-P74028/?rtype=3D10 =0A seems most like them currently ) Tracy = used to provide.

The fixed =0A hose barb side of course does no= t leak, but on the screw fitting side I =0A have a 10mmx1.0( http://www.summitracing.com/parts/RUS-670480/ =0A = ) with an o-ring and everytime I think I have the fuel drip fixed and = =0A start the pump without the engine it doesn't leak.  But, afte= r a =0A short engine run the drip returns. 

As I burned o= ut one of =0A the pumps already( important safety note make sure the f= uel selector valve =0A is not off while you have the pump turned on an= d are checking for leaks ) =0A and will need to replace it what other = inline pumps have folks been =0A using?  The 74028 flavor fuel pu= mps, the 10mm fits but does not =0A seal.  I did not use thread t= ape or other thread sealer.  And no =0A amount of tightening seem= s to keep it from leaking again.

Thoughts =0A on a fuel pump su= bstitute?  Way to seal that fitting to the existing =0A 74028 pum= p?
