<div dir="auto"><br></div><div dir="auto"><div dir="auto"><font face="sans-serif">Several years ago on an evening club drive in the Catoctin Mts of Maryland my TR4 developed running/ hesitation issues. Then it got dark & started to rain. Could not drive the car steady over 45mph. Typical fuel flow clogging issue symptoms. Fortunately we made it into Fredericksburg and a Motel.</font></div><div dir="auto"><font face="sans-serif"><br></font></div><div dir="auto"><font face="sans-serif">Next morning, still raining, the issue was apparent: in the bottom of the Glass fuel bowl- a pile of 'rust dust'. Cleaned the bowl & nursed the car home 30 miles, but it kept dying. Fortunately a Jag club friend came by and got his trailer & towed me home.</font></div><div dir="auto"><font face="sans-serif"><br></font></div><div dir="auto"><font face="sans-serif">Further examination determined sediment also in the CD carbs fuel bowls. So much for the fuel pump 'screen' being 'effective'.</font></div><div dir="auto"><font face="sans-serif"><br></font></div><div dir="auto"><font face="sans-serif">Also examination of the fuel pump (original) revealed a weak diaphragm, so while working on the carbs, ordered a new pump from TRF. </font></div><div dir="auto"><font face="sans-serif"><br></font></div><div dir="auto"><font face="sans-serif">A few months later got everything back together. The engine started right up & ran fine. But no matter how I tried to seal the threads on fuel feed of the original curved pipe inlet 'nut' to the new pump ( pipe dope, teflon tape, rtv) the leak wouldn't stop. </font></div><div dir="auto"><font face="sans-serif"><br></font></div><div dir="auto"><font face="sans-serif">Magnifying glass exam of the original Triumph Male pipe 'nut' and the female threaded bore of the new TRF pump revealed a slight thread mismatch - Chinese machining. It was not Metric either. </font></div><div dir="auto"><font face="sans-serif"><br></font></div><div dir="auto"><font face="sans-serif">So after talking with TRF, I decided to forget the mechanical pump and install an electric pump, ala Jaguar V12s & Jensen Healey / GTs (Lotus 907).</font></div><div dir="auto"><font face="sans-serif"><br></font></div><div dir="auto"><font face="sans-serif">Well, I installed a couple of different new electric pumps adjacent to the mechanical pump.</font></div><div dir="auto"><font face="sans-serif"><br></font></div><div dir="auto"><font face="sans-serif">They would never 'self prime'. </font></div><div dir="auto"><font face="sans-serif"><br></font></div><div dir="auto"><font face="sans-serif">Now, returning to the project. I removed the mechanical pump, & DRAINED the tank of the old fuel. It seems that the gravity feed when the tank is less than 1/2 full requires the elec pump to be very low ( like the original input height of the original pump, to receive fuel. </font></div><div dir="auto"><font face="sans-serif"><br></font></div><div dir="auto"><font face="sans-serif">So I am redetailing the frame (cleaning & new paint) and securing the new fuel line, inline glass Filter & elec pump right on the frame. This allows the steel feed line from the tank ( after Dremel Tool cutting) to match the new location of the electric pump.</font></div><div dir="auto"><font face="sans-serif"><br></font></div><div dir="auto"><font face="sans-serif">Next will be modifying a new copper fuel line ( semblance of originality) to meet the elec pump feed right behind & adjacent to the Water pump. The original copper pipe mated to the back of the mechanical pump , ran up and forward along the engine at the cylinder head level to the front of the engine & then across to the carburetor feeds.</font></div><div dir="auto"><font face="sans-serif"><br></font></div><div dir="auto"><font face="sans-serif">Finally hope this resolves the fuel delivery issue.</font></div><div dir="auto"><font face="sans-serif"><br></font></div><div dir="auto"><font face="sans-serif">I wanted to share a warning about the TRF pump supplier manufacturing glitch. So others can not waste years getting their TRs back to Roadworthy status.</font></div><div dir="auto"><font face="sans-serif"><br></font></div><div dir="auto"><font face="sans-serif">Obviously not going to drive a car with weeping fuel near a hot engine. At least on the TR4 & 6s, ( unlike Jaguar 6s ( have 2) or V12s ( have 3), Jensen GTs ( have 3) ; the exhaust Manifolds are on the opposite side of the engine. </font></div><div dir="auto"><font face="sans-serif"><br></font></div><div dir="auto">Sherman D Taffel </div><div dir="auto">Columbia MD and Goldvein VA </div><div dir="auto">65 TR4 CT 50054L</div><div dir="auto">( per VTR the last known TR4 produced & shipped to USA)</div><div dir="auto"><br></div><div dir="auto"><br></div><div dir="auto" id="gmail-m_513921397614640008composer_signature"><div dir="auto" style="font-size:85%;color:rgb(87,87,87)">Sent via the Samsung Galaxy S10, an AT&T 5G Evolution capable smartphone</div></div><div dir="auto"></div></div><div dir="auto"><br></div><div dir="auto"><br></div><div dir="auto" id="gmail-m_513921397614640008composer_signature"><div dir="auto" style="font-size:85%;color:rgb(87,87,87)">Sent via the Samsung Galaxy S10, an AT&T 5G Evolution capable smartphone</div></div><div dir="auto"><br></div></div>** <a href="mailto:triumphs@autox.team.net">triumphs@autox.team.net</a> **<br>
