Is there a reason the return fuel lines have to be hose? What if they were hard piped in converting to AN or similar fittings? Seams like that would be just one less point of failure.

Excellent chemical resistance. Retains higher mechanical strength at elevated temperatures compared to PTFE. High resistance to stress cracking. Made from standard PFA resin (perfluoroalkoxy), Chemfluor® PFA Tubing is widely used in the semi-conductor, laboratory, environmental and pharmaceutical industries where ultrapure chemicals (including water) require precise quality control. Priced per foot; sold in full rolls only. Do not radiation sterilize. Working temp is -320° to 500°F. |
Howdy,don't know where you got that info, but i think it is wrong. the original hose is DIN73379 type B 4.0 x 9.0 mm
very hard to find in US, i buy mine in England 50 ft at a time.

You will have to replace all the fittings. A little costly up front, but then you have easy replacement if it ever needs it. Which (unless they get damaged somehow) will never happen.how do you push that on the barb fittings on a mep-802/3? as for the 4mm versus 3.5mm the 3.5 may be correct, but look at the end of a failed hose and it looks like it was no something to large. the 4mm is only .020" larger id but is still a tight fit so i think it may be a better choice anyway.
Which hose are you talking about ? All the hoses can be replaced with the DOT nylon hose as long as you replace the fittings. The injector return lines are probably a different story, but if you can take out the fittings that go into the injectors and they are NPT threads then you can go with the nylon hose there also.I think you guys are thinking of two different hose systems.
One is the return from the injectors, that's the 3.5-4mm hose.
The other is tank to pump to ip.
