Inner side shields. May 01, 2022 02:32PM
On the inner side shields. My injection pump is offset so it sticks out a decent bit with fittings and all.
Can I cut out the part of the side shield where the pump is so I can make it more even and not stick out as far.
Or does it need to cover the pump also?

The way I read the Shielding rules on page 29 in the 2022 NTPA rule book the pump cannot act as part of shielding.
You can make a box that covers the pump,lines,etc that is part of the side shield so the rest of the shield can remain closer to the engine.

Thank you. I should have mentioned it’s ppl rules but I assume that part will be the same though.

PPL book is online

1. Shielding on v or y type engines must be from the base
of the head to two (2) inches below the crankshaft throw.
Frame may be used as all or part of the shield provided it is
solid and covers the required area.
2. Shielding on in-line engines will run from hood to two (2)
inches below crankshaft throw. Shield must be complete,
no holes accepted. Shielding must extend complete length
of block and be securely fastened.
3. All engines will have a deflection shield, running the
complete length of the block casting. Shield must be
securely fastened and must be .060 inch thick. Starters,
exhausts, fuel pumps, etc., will not be considered as part of
the shield.
