502 mag high pressure line
 

I have a need to extend the pressure lines from the cool fuel to the fuel rail .(cool fuel has to move)Does anyone make any type of 0-ring adapter fitting to go in to fuel rail as the stock fitting does. Has anyone tried cutting existing crimp off of the fitting and re-crimping new hose back on ..When someone is setting up a system with different pump and return style regulator, what is used for the high pressure hose...This is a 502 mag mpi #153???

This is the time to convert it, I wouldn't mess with the stock OE stuff. I used AN fittings and push lock hose on mine, high volume EFI pump, external bypass regulator at the end of the fuel rail and dump the excess back to the tank or filter head.

but how did you get the fuel into the rail without using the oem o-ring fitting? Was hoping someone knew of a merc o-ring to AN or pipe fitting.

I cant remember what the 502 mpi rail feed looked like, mine are 500 EFI intakes, can you post a pic ?? the may make an o-ring to inverted flare fitting

Use the OEM hoses with adapters to AN. Jegs sells them for like $4.

exactly ditch the cool fuel and run the return line to the tank. push locks are the easiest way to go.

and ditch the vts tank too while u r at it

Thank you very much .I think that is what I was looking for.

If you can make those work I'd like to see it please!
