HP Crossover line question

[tucker0104]

I recently bought a HP oil Crossover line for my 1997 f-250 7.3L. Just bought another one and am going to sell the old one. Does anyone know the part number for the plug and seals that you take out to screw the HP oil crossover line in too? Thanks for the help.

Factory numbers:

Plug: F4TZ-9K024-A, $5.75 list price, $3.80 at Tousley Ford Parts
O-Ring: F4TZ-9N693-A, $3.16 list price, $2.08 at Tousley Ford Parts

Cheers!

Kind of off topic, but I think the OP already got what he was looking for.


I got new injectors a few months ago, and I was looking into the HP crossovers. Are they beneficial to the life of the injectors? Some people say it can just be one more place for a possible oil leak. I know #8? injector can starve for oil, this won't harm it will it?

I dont know how beneficial they are but it really smoothed out how my truck runs. If you do it, get a good quality one either from Tymar or a solid line one from someone. And KEEP the plugs in the glove box with a wrench just incase you would possibly have to remove the line

Yep I have the solid ss tubing one from riffraff it really does help

I had one of the early prototypes from Riffraff on my E99. I didn't notice much change other than it idled a wee bit smoother. IMO, not a mod that has enough gains to justify the cost.

My dad owns a hydraulic shop. They are o-ring boss fitting I think? is there any reason I can't just crimp up a line? be fairly cheap..just the cost of the fitting and hose.

Maybe chaffing will be an issue?

[Patrick Feeley]

You will need to make sure that it does not get near the turbo. You will also need to ensure that the hose will be rated for the correct pressure AT the correct temperature. Most hose manufacturers will have a burst pressure rated at a specific temperature (say 4000 psi at 250F). As the temperature goes up from there the pressure rating will go down. Cheers!

I should expect to see 3000 +-, and what for EOT? 190?

Eliminate the spring checks behind your HPO lines at your HPOP, does the same thing as the HPX. Just make sure you have some spare orings when you remove the fittings.
