Engine/Transmission (1998.5 - 2002) Drilling Banjo Bolts

[Stroke This 24V]

Any of you guys drilling your stock banjo bolts out? If so what size are you getting away with or what is the recommended size. I just lost the second VP-44 in under a year. The guy @ the dealer said being he was going to be taking the banjo bolts out if I go him the size of the hole needed he would drill them before he reinstalled them.





I just want to get a little more miles out of Injection Pump Three.



Two Injection Pumps in 41,981 miles.

The banjo's from genos are drilled . 180 instead of the stock . 130. It said on the paperwork I got with mine to torque to 18ft/lbs. I know Ken Jones of Diesel Performance of Utah sells a fuel line upgrade kit that is pretty inexpensive. It gets rid of the banjo's. A fellow TDR member said he got 4 - 4. 5 psi increase just from these new hoses @ wot. http://dpofutah.tripod.com/





Hope this helps

stroke , you have all that power and stock banjos ???



i posted what i did somewhere on the site , don't know if its still here .



what i did was drill the small holes out to . a #8 drill , which is . 200 , the big holes is only 9/32 , the line internal is 5/16 , i drilled mine to 21/64 . the other restriction is the banjo fittings on the line between the lift pump and the filter ( 2000 - 2002), if you still have them they are less than 1/4 inch (if i remeber correctly , i want to say 3/16) , i just replaced that line , but i did modify a set and drilled them to 9/32 ( i think , i'd have to check ) doing this changed my WOT pressure from nothing to 3 psi , this was with the stock old spec lift pump and with it mounted on the engine .



this is a tedious task and takes time , i even modified the stock schraders , deburred everything and chamfered the small holes like they were stock . maybe i was a bit to cautious , but i was concerned with having missed a burr and it going into the VP44 ...



unless you are concerned with stock appearance i would completely ditch the banjo fittings all together ... i did ...

Try a ream instead, much easier holes will be straighter. The best way I think is to step ream the bolts, I took two steps and it worked great. 1 min. job on each bolt.
