Etech 100 psi fuel return valve

[raydurr]

Hello

Does anyone remember the part number for E7  ETech 100 psi fuel return valve?Goes on side of block near 4-5 injector. 
I am in need of a new higher pressure valve.

I know which valve you're talking about, but I can't find the part number for the 100 psi version. All the ones I can find are the 54 +/-7 PSI or lower. I'll see if I find anything, but hopefully someone else can chime in as well.

I was able to get a hold of a spec sheet that had parts going up to 80 PSI, nothing on a 100 PSI version. The 80 PSI option supersedes to 25501698, limited availability in Mack warehouses, but obtainable. No PAI cross that I could find.

They stopped using 100 PSI regs.. 80 is recommended...  100 can possibly blow out the E.U.P. o rings..

Yup they reduced this as Joey said ! As long as the fuel pressure doesn't drop off when the rpms are increased under load you should not be having power issues related TO FUEL PREASSURE !
